Sample 2010 TSAP Invitation Letter
Sample Invitation Letter to Tribe:
FROM THE DIRECTOR
U.S. CENSUS BUREAU
REGIONAL CENSUS CENTER
Dear Tribal Chair:
On behalf of the U.S. Census Bureau, I invite your tribal government to work with us to
identify and delineate tribal census tracts, tribal block groups, and census designated
places (CDPs) for your American Indian Reservation (AIR) and/or off-reservation trust
lands (ORTLs) as part of our Tribal Statistical Areas Program (TSAP). The Census
Bureau will tabulate data from the 2010 Census for your statistical areas, and post-2010
we will tabulate data for the same areas from the American Community Survey (ACS).
In addition, you are also invited to suggest census block boundaries as part of our Block
Definition Program (BDP). Statistical data from the 2010 Census and the ACS can
provide your tribe with a meaningful tool to help make informed decisions and plan for
services such as education, health, and housing.
Your tribe is eligible to delineate tribal census tracts, tribal block groups, and CDPs, and
to suggest census block boundaries through the BDP. Your eligibility to delineate these
statistical areas is based upon population data from Census 2000 for people living on
your AIR and/or ORTL. In accordance with TSAP criteria, an AIR and/or ORTL must
have population equal to or greater than 2,400 to delineate more than one tribal census
tract and equal to or greater than 1,200 to delineate more than one tribal block group.
These population thresholds apply to all people on the AIR and/or ORTL – not just tribal
members – and do not include tribal members that live off the AIR and/or ORTL.
Statistical data for your tribe can be found on the Census Bureau’s American Factfinder
website (http://factfinder.census.gov). Proposed delineation criteria for these statistical
areas were published in the April 1, 2008 Federal Register Notice (http://www.census.
gov/geo/www/tsap2010/e8-6665.pdf).
While participation in the TSAP is voluntary, this program provides your tribe the
opportunity to use local knowledge to update and/or delineate your statistical areas (in
accordance with Census Bureau guidelines) for the 2010 Census. In late 2008, the
Census Bureau will send materials to participants and you will have the option of
updating and/or delineating your tribal statistical areas using either paper maps or Census
Bureau provided Geographic Information System tools and shapefiles. (ESRI ArcGIS
version 9.2 or higher is required for this application.) We will also provide you with
detailed guidelines and criteria regarding how to delineate these statistical areas, and
Census Bureau staff will be available to answer questions and lend assistance. You will
have 120 calendar days from the date you receive your TSAP materials to complete your
review and submit your tribal census tract, tribal block group, and CDP delineations, and
block boundary suggestions to the Census Bureau for processing. A final copy of your

updated boundaries will be made available to you in late calendar year 2009 and you will
then have the opportunity to verify boundaries and to discuss any changes made by the
Census Bureau with our Geography staff.
We request that you review and complete the attached TSAP participant information
sheet within two weeks. You may return the information sheet by mail using the postage
paid envelope provided, or by fax at the number below. You may also provide the
information by calling or e-mailing Census Bureau Geography staff at the telephone
number and e-mail address provided below. If you decline participation in the TSAP, the
update of your tribal statistical areas will default to Census Bureau staff who will conduct
the review and delineation for the 2010 Census.
Additional information about the 2010 TSAP is available at:
http://www.census.gov/geo/www/tsap2010/tsap2010.html
If you have any questions regarding the 2010 TSAP, please contact the Regional Census
Center by telephone at XXX-XXX-XXXX, by fax at XXX-XXX-XXXX, or via e-mail at
[email protected].
We look forward to working with you.
Sincerely,

Sample Invitation Letter to State Liaison:
Mr. Benjamin Moreira,
Planning and Economic Development Specialist
771 South Lawrence Street, Suite 106
Montgomery, Alabama 36130
Dear Mr. Moreira:
The Governor’s Office of Alabama has informed the U.S. Census Bureau that you will be our
liaison for the 2010 Census geographic programs for state-recognized American Indian tribes.
This letter serves both to invite you to participate in these important programs and to confirm that
the inventory of state and federal tribes in our database is correct.
Geographic programs for state-recognized tribes include the State Reservation Program (SRP)
and the Tribal Statistical Areas Program (TSAP). The SRP seeks to determine the current
inventory and legally defined boundaries of state American Indian Reservations. As part of
TSAP, you will have the opportunity to work with state-recognized tribes in Alabama that do not
have a reservation or trust lands in order to update or to define State Designated Tribal Statistical
Areas (SDTSAs). SDTSAs generally encompass a compact and contiguous area in which there is
structured or organized tribal activity and a concentration of individuals who identify with a
specific state-recognized American Indian tribe. (SDTSAs were called State Designated
American Indian Statistical Areas [SDAISAs] during Census 2000.) Proposed criteria for the
update or delineation of State Reservations and SDTSAs for the 2010 Census were published in
the April 1, 2008 Federal Register Notice (http://www.census.gov/geo/www/tsap2010/e86665.pdf). Your participation provides an opportunity to use local knowledge in the
update/delineation process.
The Census Bureau will tabulate statistical data from the 2010 Census for State Reservations and
SDTSAs, and post-2010 we will be tabulating data for the same areas from the American
Community Survey (ACS). Meaningful statistical data from the 2010 Census and the ACS can
provide both states and state-recognized tribes with a tool to help make informed decisions and
plan for services such as education, health, and housing.
Our records show that the state of Alabama has granted recognition to the tribes listed below.
State- recognized tribes that have reservations or that had SDTSAs delineated during Census
2000 are listed with the names of their reservations or statistical areas. Please review the list for
accuracy and return any updates or corrections on the 2010 Census State Geographic Programs
Participant Information Sheet attached.
State Recognized Tribes
MOWA Band of Choctaw Indians - MOWA Choctaw (state) Reservation
Cherokees of Southeast Alabama - Cherokees of Southeast Alabama SDAISA
Cherokee Tribe of Northeast Alabama - Cherokee Tribe of Northeast Alabama SDAISA
Echota Cherokee Tribe - Echota Cherokee SDAISA
MaChis Lower Creek Tribe - Machis Lower Creek SDAISA
Star Clan of Muscogee Creeks - Star Musckogee Creek SDAISA
Piqua Shawnee Tribe
United Cherokee Ani-Yun-Wiya Nation

Additionally, we are including below a list of tribes in Alabama that have been recognized by the
federal government. While the Census Bureau works directly with federally recognized tribes,
we ask that you review the list for accuracy and note any corrections in the appropriate space on
the Participant Information Sheet.
Federal Tribes
Poarch Band of Creek Indians - Poarch Creek Reservation
In late 2008, the Census Bureau will send you all of the materials needed for updating and/or
delineating state-recognized tribal boundaries using either paper maps or Census Bureau provided
Geographic Information System tools and shapefiles. (ESRI ArcGIS version 9.2 or higher is
required for this ESRI ArcGIS extension.) You will also be provided with detailed guidelines and
criteria regarding how to report state reservation boundaries and update or delineate SDTSAs.
Census Bureau staff will be available to answer questions and lend assistance as needed. We
encourage you to work with the tribes in your state to optimize the results for all stakeholders and
data users.
You will have 120 calendar days from the date you receive the materials to complete your review
and submit your delineations and/or updates to the Census Bureau for processing. A final copy of
your updated boundaries will be made available to you in late 2009. You will have the
opportunity to verify the boundaries and discuss any changes that may have been made by the
Census Bureau with our Geography Staff.
We request that you complete the 2010 Census State Geographic Programs Participant
Information Sheet within two weeks of receipt. You may return the Information Sheet by mail
using the postage paid envelope provided, or by fax at the number below. You may also provide
the required information by calling or e-mailing the Census Bureau Geography staff at the
telephone number and e-mail address provided below.
Additional information regarding the 2010 TSAP program is available at:
http://www.census.gov/geo/www/tsap2010/tsap2010.html
If you have any questions regarding the 2010 State Reservation or SDTSA Programs, please
contact the Atlanta Regional Census Center by telephone at 404-332-2721, by fax at , or via email at [email protected].
We look forward to working with you.

Introduction to the Tribal Statistical Area Program materials
The U.S. Census Bureau would like to thank your tribal government for considering participation
in the Tribal Statistical Areas Program (TSAP), a geographic program conducted prior to the
2010 Census. As noted in the invitation letter you should have received earlier this fall, through
the TSAP your tribe is eligible to delineate and/or update tribal census tracts, tribal block groups,
and census designated places, and to suggest census block boundaries through the block
definition project. Because you indicated an interest in the program or we did not receive a
response, we have enclosed the materials to accomplish your statistical area delineations. If you
do not wish to participate or if you have no changes to your tribal statistical areas, please fill out
and return the form below to the Census Bureau’s Regional Census Center (RCC) by mail with
the enclosed self addressed stamped envelope or by fax (XXX-XXX-XXXX).
You have the option of using paper maps or an ESRI® ArcMap™ GIS (version 9.2 or 9.3)
software extension to accomplish your delineation work and the materials and guidelines for each
option are enclosed with this letter. Participants using paper maps may return their submission
with the attached Business Reply Mail label that will cover the return mailing costs. The ESRI
ArcMap GIS software extension, in the form of an executable installation file and geospatial data
(in shapefile format) are found on an enclosed CD. Also on the CD are the Guidelines for Digital
Submission (a pdf document) which includes software installation instructions, descriptions of the
tools included with the extension, and guidance in the delineation of your eligible statistical areas.
Participants choosing digital submission will use the internet to upload their digital delineations.
From the date you receive this package, you will have 120 calendar days to complete either a
paper map or digital GIS submission for your tribal statistical areas. At any point in the process
please do not hesitate to contact ###staff name contact### at the RCC for additional guidance,
help, or any questions regarding your delineation project work. The U.S. Census Bureau looks
forward to working with you to delineate your 2010 Census tribal statistical areas.

1.0 Introduction
The U.S. Census Bureau is the premier source of information about the American people and the
economy. The U.S. Constitution mandates that a census be taken every 10 years in order to reapportion
the House of Representatives. The data gathered by the decennial census and other Census Bureau
programs are used for several other purposes, including the allocation and distribution of funds to state,
local and tribal governments. Census information shapes important policy decisions that in turn shape
the nation’s social and economic conditions. While best known for the decennial census, the Census
Bureau conducts numerous surveys and censuses that measure changing individual and household
demographics and the entire economic condition of the nation.
Census data help tribal elders and leaders understand what their communities need. Many tribal
communities use census information to attract new business and plan for growth. In fact, many tribes
and tribal organizations use census data to plan new facilities and programs for the communities they
serve.
The Tribal Statistical Areas Program (TSAP) is part of an ongoing effort to enhance the reporting of
meaningful statistical data for American Indian and Alaska Native areas. Through this program tribes
have the opportunity to identify and delineate the statistical areas and block boundaries from which the
Census Bureau will tabulate data for the 2010 Census and the subsequently occurring American
Community Survey (ACS). Meaningful statistical data from the 2010 Census and the ACS can provide
tribes and other data users with tools to help make informed decisions, and plan for services such as
education, transportation, health, and housing.
Tribes and states should strongly consider participating in the TSAP for the 2010 Census. The program
offers federally recognized tribes and designated state officials for state-recognized tribes greater control
and improved flexibility to identify and propose changes to the boundaries of American Indian and
Alaska Native statistical areas. Nonetheless, participation in the TSAP is voluntary. If your tribe or
state chooses not to participate, the Census Bureau may revise the boundary of an existing area or
delineate a new area in accordance with published criteria and guidelines. TSAP includes the following
statistical areas:
ƒ
ƒ
ƒ
ƒ
ƒ
ƒ

Alaska Native village statistical areas (ANVSAs)
Oklahoma tribal statistical areas (OTSAs) and tribal subdivisions on OTSAs
state designated tribal statistical areas (SDTSAs)
tribal designated statistical areas (TDSAs)
tribal census tracts and tribal block groups – on American Indian reservations (AIRs) and/or offreservation trust lands (ORTLs)
census designated places (CDPs)

In preparation for Census 2010, the Census Bureau also has developed the State Reservation Program
(SRP). The SRP occurs once before each decennial census, and is a survey of state AIRs for those states
with state-recognized tribes that are not also federally recognized. Its purpose is to determine, solely for
data collection and tabulation by the Census Bureau, the complete and current inventory and the correct
attributes (names, legal descriptions, official status) and official, legal boundaries of the state AIRs in
each state. Through the State Reservation Program, the Census Bureau also accepts additions and

updates to features such as roads or rivers that serve as a boundary for the state AIR, as well as address
range break information at the boundaries.
More information about the background and components of these geographic areas as well as the
delineation update criteria and guidelines can be found in the Federal Register notices for American
Indian Areas (Vol. 73, No. 221, Friday, November 14, 2008, p. 67470) and Alaska Native Areas (Vol.
73, No. 214, Tuesday, November 4, 2008, p. 65572). These notices may be accessed from our TSAP
webpage at http://www.census.gov/geo/www/tsap2010/tsap2010.html. Copies are also included on the
enclosed CD.
The instructions provided in this document will guide participants through the computer based
Geographic Information Systems (GIS) mapping process using ESRI® ArcGIS® ArcMap™ software
(version 9.2 or 9.3) and the Census Bureau’s TSAP Extension for ArcMap. Following this background
and information section, an explanation of delineation eligibility and the installation instructions are
presented. Directions for starting a TSAP project and delineating tribal statistical areas are then
described offering specific criteria and guidelines for each particular area type. This is followed with a
detailed presentation using the TSAP Extension’s Tools. The guidelines conclude with a review of the
quality control and submission processes.
Disclosures to Respondents
The Geography Division manages programs to continuously update features, boundaries, addresses, and
geographic entities in the Master Address File / Topologically Integrated Geographic Encoding and
Referencing System (MAF/TIGER) database (MTdb) that is used to support programs and to conduct
the census and surveys. The TSAP program was developed to give tribes the opportunity to review and
update, if necessary, statistical tribal entities for use in tabulating and publishing data from the 2010
Census, the American Community Survey, and other surveys.
Public reporting burden for this collection of information is estimated to average 48 hours per
respondent, including time for reviewing instructions, assembling materials, organizing and reviewing
the information, and reporting any needed changes. We anticipate that an estimated 650 participants will
respond. Remaining entities may be worked by Census Bureau regional staff. For larger areas or areas
with many changes, however, the respondent burden may be 180 hours or longer to complete. Please
send comments regarding this burden estimate or any other aspect of this collection of information,
including suggestions for reducing this burden to:

No agency may conduct and no person may be required to respond to a collection of information unless
it displays a valid Office of Management and Budget (OMB) approval number. The OMB approval
number for this information collection is 0607-0795.

1.1 About the TSAP ESRI® ArcGIS® ArcMap™ (version 9.2 or 9.3) Extension
The Census Bureau has developed a TSAP Extension for ESRI’s ArcMap version 9.2 or 9.3 that
provides a suite of GIS data management and editing tools/commands designed for participants to
identify, delineate, and review statistical areas. Project inception, quality control, data submission, and
workflow administration are all included in the data management features of the extension. In addition
to the inherent functionality of the ArcGIS software, the extension’s unique editing tools consist of
geographic area assignment, block boundary definition, tribal tract/tribal block group type attribution, as
well as line editing and polygon split/merge functions.
Essential Census geographic datasets, used in the review and delineation of your areas, are provided
with the extension on CD. These geographic datasets will be used to create the workspace for your
delineation and review tasks (as explained in the Starting a Project section). Additional GIS data such
as imagery, can be added to your project using ArcMap’s standard Add Data command button and other
tools.
In addition to digital submission, the TSAP offers participants the option of using paper maps to
delineate their tribal statistical areas. Paper map participants draw their delineations by hand directly
upon maps and return their paper map submission by postal mail to the Regional Census Center (RCC)
using a prepaid Business Reply Mail label. If you would prefer to accomplish your delineations with the
paper map option and did not receive paper map materials and guidelines please contact the RCC.
1.2 Schedule
In October 2008, the Census Bureau mailed formal invitation letters to tribal officials eligible to
delineate tribal statistical areas. These guidelines accompany the delineation materials required to
complete the work are scheduled to arrive in January 2009. Tribes have 120 days from the date they
receive these materials to review and submit their tribal statistical area delineations or updates to the
Census Bureau’s RCCs. In late 2009/early 2010, after the Census Bureau has reviewed and
incorporated your statistical areas into our geographic database, you will receive new maps or digital
files so that you can verify that we have inserted your boundaries correctly. If you have questions
regarding your delineation or submission, assistance will be available from geographers at your RCC
(see Appendix 5 for contact information).
1.3 The Boundary and Annexation Survey
The Boundary and Annexation Survey (BAS) is an annual Census Bureau survey of legal geographic
entities that includes federal AIRs, ORTLs, and any associated tribal subdivisions. Whereas the TSAP
provides the process for reviewing and updating those AIAs that are statistical geographic entities (tribal
census tracts, tribal block groups, and census designated places), the BAS provides the process for

6

reviewing and updating AIAs that are legal federal geographic entities, such as the reservation itself,
tribal subdivisions and ORTLs. Its purpose is to determine, solely for data collection and tabulation by
the Census Bureau, the complete and current inventory and the correct names, legal descriptions, official
status, and official, legal boundaries of the legal geographic entities with governmental authority over
certain areas within the United States, as of January 1 of the survey year. The BAS also collects specific
information to document the legal actions that established a boundary or imposed a boundary change. In
support of the government-to-government relationship with federally recognized American Indian tribes,
the Census Bureau works directly with tribal officials on the BAS. Through the BAS, the Census
Bureau also accepts updates to features such as roads or rivers, and address range break information at
the boundaries. If you wish to update boundaries for you reservation, off-reservation trust lands or legal
tribal subdivisions, you should do so through the BAS.
For more information about the BAS, contact your RCC or see the Census Bureau's Web
site at http://www.census.gov/geo/www/bas/bashome.html. The BAS Respondent
Guide for federally recognized tribes is available at:
http://www.census.gov/geo/www/bas/bas09/bas09_mat_aia.html
1.4 Important Information on Features
Feature boundaries of statistical areas should follow specified legal or administrative boundaries that do
not change greatly over time, or permanent, visible features, such as roads, perennial streams, railroads,
and high-tension power lines. Permanent visible features should be easily locatable in the field by
Census Bureau staff without ambiguity. The acceptable visible boundary features are:
ƒ
ƒ
ƒ
ƒ
ƒ
ƒ
ƒ
ƒ
ƒ

pipeline (above ground)
powerline (above ground, high-tension)
aerial tramway/ski lift
natural topographic features
cliff/escarpment
perennial shoreline
railroad features (Main)
carline, streetcar track, monorail, other mass transit rail
interstate highway or primary road with limited access
primary road without limited access, US highway, state highway or county highway, secondary
and connecting roads
local neighborhood road, rural road, city street
service drive (usually along a limited access highway)
alley
fencelines

Data user and Census Bureau experience has shown that some features make better boundaries than
others, and the same type of feature can make an excellent boundary in one place and a poor one in
another. Rivers, major canals, lakes, and other bodies of water often make good statistical area
boundaries because they generally limit access from one area to another and rarely change relative
location. Other features that limit access between areas, such as interstate and other major highways,
railroad tracks, and the ridges of mountain ranges, also make good statistical area boundaries. In some
instances, however, such a feature unifies a community, for example, a lake forming the core of a
recreational housing development or a through street forming the spine of a subdivision. In these
circumstances, the statistical area boundary should include the entire area of the lake or both sides of a
unifying street to better encompass similar community patterns.
In general, when delineating boundaries in bodies of water represented as polygons and having area
(lakes, reservoirs, bays, oceans, and wide rivers), the boundary should follow a line bisecting the water
body rather than following a shoreline. Wherever possible, use an existing line in water (for example, a
county line in the middle of a river) rather than adding a new line.
Tribal officials delineating tribal statistical areas may only add nonvisible lines as a boundary if other
acceptable boundary features such as roads, rivers, streams, shorelines, trails and ridgelines, are not
available and they aid in a tribal statistical area meeting other specific delineations criteria and/or
guidelines. The Census Bureau staff will contact you if they require more information or have questions
about feature updates submitted as part of the 2010 TSAP.
1.5 Boundary Feature Updates
The Census Bureau has spent the last six years enhancing the spatial accuracy of the roads in our
database system. The local files used during this project were required to have an overall average
accuracy of 7.6 meters while some files had better accuracy.
Although much of the street network is vastly improved, as you work with our shapefiles you may
notice that in some counties the street and boundary features look distorted. A line that should be
straight may have a noticeable kink or pointed shape. The Census Bureau is working to correct these
problems, and if you need to use a feature that is distorted in our shapefiles follow the guidelines below.
The Census Bureau is also now moving forward with our 2010 Census field canvassing and collection
activities. This means that we are no longer processing realignments to our street network. What is
critical for the success of the 2010 Census data tabulation is the location of roads relative to the
tabulation entity boundary. As long as the road is within the correct entity, the population and housing
will be properly reported. The guidelines below explain what updates are acceptable as part of the
TSAP.
It is critical that participants understand that the TSAP is not intended for street feature updates except
where a boundary follows a road (or other visible feature such as a stream) and the road is not reflected
in our file. For this reason the Census Bureau can not accept street (or other) feature updates that do not
follow the guidelines below:
Guidelines for Updating Features

8

1. If a road is missing and it forms the boundary for the area you are defining, add the road and
provide the name.
2. If you can not correctly delineate the boundary for an entity you are updating because the feature
you need to follow is incorrectly located, mislabeled or distorted in the Census Bureau’s file, we
request that you use the problematic boundary and report the existence of the identified
problematic boundary feature(s). The problematic boundary may be reported to the Census
Bureau through the RCC (contact information is contained in Appendix 5). The Census Bureau
will then correct the feature and adjust your delineation accordingly.
3. Do not add streets that are missing for an entire housing development (add only streets that are
needed to form a boundary). We will be adding new or missing streets during our address
canvassing operation which will occur in the spring and early summer of 2009. The Census
Bureau will provide verification materials to each participant that returns their submission in the
correct format and within the allotted 120 days that will show the results of address canvassing.
If these streets are still missing at that time, we will accept these as adds.
4. When adding a boundary that is within 30 feet (10 meters) of an existing line in the Census
Bureau’s shapefile do not add an additional line. Instead use the existing line features wherever
possible.
1.6 Criteria
All American Indian Areas (AIAs) must follow a standard set of criteria that support a shared purpose of
providing a meaningful and relevant geographic framework for tabulating data for the Census. It is the
responsibility of the Census Bureau to ensure that geographic entity criteria can achieve the goal of
providing meaningful, relevant, and reliable statistical data, and that the final criteria for geographic
entities are met. While aware that there are secondary uses of geographic entities and the data tabulated
for them, the Census Bureau will not modify their boundaries or attributes specifically to meet these
secondary uses, including those of other government agencies. If a change is made to a geographic
entity to meet one specific purpose, it may be detrimental for other programs that also use these entities.
The Census Bureau will use the criteria and guidelines to help ensure that tribal statistical areas
delineated for the 2010 Census, support the intended purpose of the program, provide useful and
meaningful data for the tribe they represent, and enhance the ability for data users to make more
meaningful comparisons between data.
Criteria are rules that must be followed by all officials delineating statistical AIAs for the 2010 Census,
while guidelines are suggestions for improving the relevance and utility of statistical AIAs. Criteria and
guidelines for specific tribal statistical area entities are explained in section 5.0 Delineating your
statistical area.

2.0 Delineation Eligibility of American Indian and Alaska Native Areas
American Indian tribes and Alaska Native villages reside in a diverse landscape of legal, cultural, social,
and historical contexts. This diversity has resulted in an equally varied identification of geographic
boundaries and statistical areas for American Indian and Alaska Native areas (AIANAs). For the 2010
Census, the TSAP offers the opportunity to delineate the following AIANAs: tribal census tracts, tribal
block groups, census designated places (CDPs), Oklahoma tribal statistical areas (OTSAs), OTSA tribal
subdivisions, tribal designated statistical areas (TDSAs), state designated tribal statistical areas

9

(SDTSAs), State recognized American Indian Reservations (SAIRs), and Alaska Native village
statistical areas (ANVSAs). Federally recognized tribes with American Indian reservations (AIRs)
and/or off-reservation trust lands (ORTLs) are eligible to suggest 2010 Census tabulation block
boundaries through the Block Definition Project (BDP). The eligibility of a tribe to delineate a
particular AIANA is expressed in Table 1. In addition, a list of all TSAP eligible tribes and the AIANA
types that they are eligible to delineate is presented in Tables A-D of Appendix 1 (Table A. Federally
Recognized Tribes, Table B. Alaska Native villages, Table C. Federally Recognized Tribes in Oklahoma
with a former American Indian reservation in Oklahoma, Table D. State Recognized Tribes).

5.0 Delineating your statistical area
General Guidance
The TSAP extension is designed to assist participants with the review and delineation of the American
Indian and Alaska Native areas (AIANAs) included in the 2010 Census TSAP. The eligibility to
delineate specific AIANAs was presented in section 2 of this document and may also be found for your
tribe in Tables A-D of Appendix 1 (Table A. Federally Recognized Tribes, Table B. Alaska Native
villages, Table C. Federally Recognized Tribes in Oklahoma with a former American Indian reservation
in Oklahoma, Table D. State Recognized Tribes). This section is intended to offer guidance in the
delineation process for each type of AIANA through an introduction, example delineation scenario, and
the listing of specific criteria and guidelines. In the AIANA list below please refer to the italicized
section listings and page forward for guidance in the delineation of your tribal statistical area.
AIANAs to be reviewed and updated include:

Tribal designated statistical areas (TDSAs) Section 5.6
State designated tribal statistical areas (SDTSAs) Section 5.7
State American Indian Reservations Section 5.8

As noted the TSAP extension has been developed for ESRI’s ArcGIS software. Therefore as with any
ArcMap project, additional spatial datasets that may be useful in your delineation work for reference,
such as land use, zoning, aerial imagery, etc. may be added at anytime to supplement your TSAP
projects. The TSAP extension does not offer any custom tools for adding supplemental datasets to the
data frame, rather you must utilize the existing Add Data
toolbar.

command found on ArcGIS’s Standard

All data supplied by the Census Bureau for use with the TSAP extension is delivered in geographic
projection, North American Datum 1983 (NAD83). The TSAP data is supplied in shapefile format and
is thus not topologically integrated. The Census Bureau requests that tribal participants maintain the
shapefile format and projection throughout all use of the TSAP extension from review and delineation
to final submittal. It is necessary to maintain the delivered shapefile and projection format because all
submitted delineations will be incorporated by the Census Bureau into a seamless topologically
integrated spatial database. As well, Census Bureau provided shapefiles must be used for the actual
delineation work. All delineations submitted in other file formats and/or projections will cause a delay
in processing and acceptance.
If you believe the boundary for your reservation or off-reservation trust land is not correct, please
contact the Census Bureau RCC (see Appendix 5 for your RCC’s contact information).

Things to consider when delineating CDPs, ANVSAs, TDSAs and SDTSAs
Since CDPs, ANVSAs, TDSAs and SDTSAs also will be used to tabulate and present period estimates
from the American Community Survey, defining officials should consider that, as a general rule, period
estimates of demographic characteristics for geographic entities with small populations will be subject to
higher variances than comparable estimates for geographic entities with larger populations. In addition,
the Census Bureau’s disclosure rules may have the effect of restricting the availability and amount of
data for geographic entities with small populations. The more closely a CDP, ANVSA, TDSA, and
SDTSA boundary relates to the distribution of tribal members and American Indians receiving
governmental services from the tribe, and does not include large numbers of people and households not
affiliated with the tribe, the more likely that data presented for the CDP, ANVSA, TDSA, and SDTSA
will accurately reflect the characteristics of the intended tribal population.
Although eligible, in a few cases a tribe may elect not to delineate a CDP, ANVSA, TDSA, and SDTSA
if it will not provide meaningful, relevant, or reliable statistical data because the member population
now resides in numerous other locations or has been completely subsumed by non-member and/or nonAmerican Indian populations. In such instances, defining a CDP, ANVSA, TDSA, and SDTSA will not
improve the presentation of statistical data relating to tribal members. These tribes may still be able to
receive meaningful, relevant, and reliable statistical data for their tribal membership at higher levels of
census geography through the characteristic of tribal affiliation.

5.1 About tribal census tracts and tribal block groups
Tribal census tracts are delineated within federally recognized AIRs/ORTLs, and may contain one or
more tribal block groups. Tribal block groups in turn represent a collection of adjacent census blocks.
Together these statistical areas make up a nested geographic hierarchy.
Table 2. Tribal census tract and tribal block group thresholds

Maximum

The Census Bureau recommends minimum/maximum and optimal population and housing unit
thresholds for tribal census tracts and tribal block groups (see Table 2 above). In accordance with TSAP
criteria, an AIR/ORTL must have population equal to or greater than 2,400 or a housing unit count equal
to or greater than 960 to delineate more than one tribal census tract. To delineate more than one tribal
block group an AIR/ORTL must have population equal to or greater than 1,200 or a housing unit count
equal to or greater than 440. If an AIR/ORTL lacks the population/housing unit count to delineate more
than one tribal census tract/tribal block group the Census Bureau will delineate one tribal census tract
and tribal block group coextensive with the entire AIR/ORTL. These thresholds apply to the entire
population living on, and housing units existing within the AIR/ORTL – not only American Indians or
Alaska Natives, and not only tribal members. These thresholds do not take into account and do not
include Tribal members that live outside the boundaries of the AIR/ORTL. These thresholds are in
keeping with those established for the Participant Statistical Areas Program (PSAP) and were
determined based on comprehensive consultations with statisticians and demographers regarding data
accuracy and privacy concerns. Areas delineated with population or housing counts below these
thresholds may not have data released due to data disclosure prevention. Areas above these maximum
thresholds may lose the data richness and usability that may be attained with the optimal thresholds.
Tribal census tracts and tribal block groups vs. standard census tracts and standard block groups
Census tracts are the oldest and one of the most utilized statistical geographic entities for which the
Census Bureau tabulates data. The primary purpose of census tracts is to provide a set of nationally
consistent small, statistical geographic units, with stable boundaries, that facilitate analysis of data
across time. Standard census tracts always nest hierarchically within states and counties. Standard
block groups are subdivisions of standard census tracts and always nest hierarchically within standard
census tracts. Standard block groups provide the geographic framework within which the Census
Bureau defines and numbers census blocks, with the block group number serving as the first digit for
each census block in the block group.
Tribal census tracts and tribal block groups are conceptually similar and equivalent to standard census
tracts and block groups. They recognize the unique statistical data needs of federally recognized
American Indian tribes by providing meaningful, relevant, and reliable data for small geographic areas
within the boundaries of federally recognized AIRs and/or ORTLs. The delineation of tribal census
tracts and tribal block groups allows for an unambiguous presentation of census tract and block group
level data specific to an AIR and/or ORTL, without the imposition of state or county boundaries, which

20

might artificially separate American Indian populations located within a single AIR and/or ORTL. To
this end, tribal census tracts and tribal block groups may cross county or state boundaries, or both.
For the 2010 Census, tribal census tracts and tribal block groups will be for the first time identified as a
geographic framework completely separate from standard census tracts and standard block groups. With
the development of an entirely separate tribal geographic framework, tribal participants have greater
freedom to begin their delineations from scratch without need to consider compatibility with Census
2000 tracts and block groups. Aside from the intent presented in the previous paragraph the
identification of tribal census tracts and tribal block groups for the 2010 Census also seeks to eliminate
data issues associated with previous censuses, so that for the 2010 Census more census tracts and block
groups, both tribal and standard, will meet the population and housing unit thresholds. The separation of
tribal and standard geographic frameworks will apply to data tabulation products, as well as to
geographic information products.
While there will be a separate hierarchy for standard and tribal census tracts and block groups in 2010,
there will only be one set of 2010 tabulation blocks. Tabulation blocks are the smallest geographic unit
for which the Census Bureau tabulates decennial census data. Tabulation blocks will be numbered with
a 4-digit code, the first digit being the number of the standard block group in which it nests. For
example, tabulation block 1001 is in standard block group 1 and block 2001 is in standard block group 2.
Because census blocks will be numbered within standard block groups and tribal block groups will be
identified uniquely from standard block groups, there will not be a relationship between tribal block
group identifiers and census block numbers. Thus, tribal block group A might contain census blocks
numbered in different ‘‘thousand’’ ranges (e.g., blocks 1001, 2001, and 3001).
An explanation of the tribal census tract and tribal block group code labels
When working with new or existing tribal census tracts and tribal block groups you will respectively
notice their ten and eleven digit identification code labels. For raw data work processes such as the
delineation tasks you are accomplishing with the TSAP Extension, the entire code for both tribal census
tracts and tribal block groups are used when labeling features. The entire code may not be present on
other Census Bureau data products including the American Fact Finder website.
Tribal census tract example
4625T00400
The first four characters identify the American Indian Area (AIA). The middle four characters
beginning with “T” identify the tribal census tract. The last two characters are a tract suffix that will
identify split tracts.
Tribal block group example
Tribal block groups add to the tribal census tract code one additional character. The example below is a
code for tribal block group “A” which is within the tribal census tract “T004” of AIA 4625.
4625T00400A

21

Delineating tribal census tracts
Delineations should begin with a reading of the criteria and guidelines for tribal census tracts found
below:
Tribal Census Tract Criteria and Guidelines
The criteria for tribal census tracts are:
1. Tribal census tracts may not cross AIR/ORTL boundaries.
2. The entire land and water area of an AIR/ORTL must be covered by one or more tribal census tract.
3. Tribal census tracts will be labeled by a “T” followed by three digits, beginning with “T001, T002,
etc.”
Guidelines for delineating tribal census tracts are:
1. Optimally, census tracts should have 4,000 people or 1,600 housing units. Meeting or exceeding the
optimum thresholds will help improve the reliability of sample data for tribal census tracts.
2. Each tribal census tract must encompass at least 1,200 people or at least 480 housing units unless it
is flagged as a special land use tract (see section 6.10).
3. A tribal census tract must comprise a reasonably compact and contiguous land area.
4. Tribal census tract boundaries should follow visible and identifiable features.
Next, review the 2000 Census tract boundaries and inspect the location and spatial extent of all existing
statistical areas as well as the corresponding demographic data reported from the 2000 Census.
Demographic data can easily be found using the TSAP Geography Manager
tool. Select Tribal
Census Tracts as your work layer and All as your update type. In the Current Work District pull-down
menu scroll through the available tracts. Notice that as each is selected, demographic attributes are
displayed beneath the Current Work District within the TSAP Geography Manager. Tracts falling
within or outside the population and/or housing unit thresholds are symbolized accordingly (red outline:
outside thresholds, green outline: within thresholds). It should again be noted that if your tribe is
eligible for only one tribal census tract, the Census Bureau will delineate a single tribal census tract
coextensive to your AIR/ORTL boundary. In the example below, an AIR with three census tracts is
depicted. The demographic attributes for each tract are present in the three following screenshots of the
TSAP Geography Manager on the next page.

22

In the scenario presented on the previous page, two tracts (outlined in red) fall outside the population
and housing unit thresholds required for tribal census tracts. The delineation of the tracts appears to be
based on standard geographic area governmental unit boundaries (e.g. counties and states) rather than
demographic rationale, and may not aid in the accurate reporting of the tribe’s statistical data. An
appropriate solution would be the merging of the three tracts into one contiguous entity. This is
accomplished by using the Merge Tool
found on the TSAP Tools toolbar (see Section 5.9). A new
tribal census tract, 4625T00600, with correspondingly summarized demographic data is formed from the
merging process (see image below).

23

Creating New Tribal Census Tracts
Continuing from the preceding scenario, the subject AIR/ORTL is eligible for two new tribal census
tracts. When creating new tribal census tracts, it is recommended that the Assign
Geography tool is
used to maintain the nesting relationships between the tracts and the AIR/ORTL. Not using this method
of delineation may result in blocks that are unassigned to a tribal census tract, which will slow the final
quality control process.
Begin the delineation by selecting Tribal Census Tracts as your work layer and All as your update type.
In the Current Work District pull-down menu select New District, then select the appropriate New
District Parameters and click OK (see images below).

The new tribal census tract, assigned with a new tribal tract number, is then created and displayed in the
Geography tool, select and
Current Work District, and you may begin adding area. Using the Assign
add census blocks until a tribal census tract is delineated (see image below).

The example above presents two tribal census tracts that both meet all necessary criteria. If a tract falls
below the population or housing unit thresholds (tracts below thresholds will be shown in red), select the
tract in the Current Work District and again use the Assign
Geography tool add area until all tracts
meet threshold criteria.

24

5.2 Delineating Tribal block groups
Tribal block groups are aggregations of census blocks within a tribal census tract. Block groups provide
a geographic summary unit for census block data, and represent the smallest geographic area that data
will be reported for the American Community Survey. Therefore the delineation of tribal census block
groups should be recognized as the most flexible opportunity for the collection of demographic data for
population centers, unique land uses, group quarters, and transitional/temporary communities within a
single census tract.
Tribal Block Group Criteria and Guidelines
The criteria for tribal block groups are:
1. Tribal block groups must not cross tribal census tract boundaries.
2. Because tribal census tracts must cover the entire area of each AIR/ORTL, by definition, tribal block
groups also must cover the entire area of each AIR/ORTL.
3. Tribal block groups will be designated with a single capital letter from “A” through “IC” (except for
the letter “I”). Tribal block group identifiers must be unique within tribal census tracts.
Guidelines for delineating tribal block groups are:
1. Each block group must encompass at least 600 people or at least 240 housing units unless it is
coextensive with a flagged special land use tract.
2. A block group must comprise a reasonably compact, contiguous land area.
3. Noncontiguous block groups are permitted only where a contiguous area or inaccessible area would
not meet population or housing unit count requirements for a separate tribal block group, in which
case the non contiguous or inaccessible area must be combined with a proximate block group.
4. Block group boundaries should follow visible and identifiable features.

As with tribal census tracts, your review should begin with an
inspection of the 2000 Census block groups and the corresponding
demographic data reported for the 2000 Census. Using the TSAP
Geography Manager
tool, select Tribal Block Groups as the
current work layer, and All as the update type. In the Current Work
District pull-down menu, scroll through and select any block group to
see its demographic data. An example block group selection using the
TSAP Geography Manager is shown in the image to the right.

25

In the following example, all of the reservation’s block groups are displayed. Block groups outlined in
red are outside the established population and/or housing unit thresholds while block groups outlined in
green are within. The reservation is displayed by a transparent green shade.

With so many block groups falling outside the thresholds it is apparent that some will need to be merged.

5.3 Delineating Census designated places (CDPs)
Census designated places (CDP) are statistical geographic entities that generally represent closely settled,
unincorporated communities that are locally recognized and identified by a single name. A CDP should
be composed of a mix of residential and commercial structures, and have at least some housing or
population, ideally both. The purpose of delineating a CDP is the creation of a statistical area equivalent
to its counterpart – an incorporated governmental unit such as a city, town, or village. CDPs may not be
partially or entirely within another incorporated place or CDP, and should not be coextensive with any
other Census geographic entity (i.e. tract, AIR/ORTL, etc.). The boundaries should follow visible
features such as streams, roads, railroad tracks, or ridgelines whenever possible.
CDP Criteria and Guidelines
The criteria for CDPs are:
1. CDPs cannot be coextensive with an entire AIR, ORTL, OTSA, or any other AIA.
2. CDPs may extend off AIRs, ORTLs, or OTSAs.
3. A CDP may not have the same name as an adjacent or nearby incorporated place. If the community
does not have a name that distinguishes it from other nearby communities, then the community is not
a distinct place and should not be submitted as a CDP.
4. A CDP may not be located, either partially or entirely, within an incorporated place or another CDP.
5. A CDP may be located in more than one county.
6. A CDP must not cross state boundaries.
Guidelines for delineating CDPs are:
1. A CDP constitutes a single, closely settled center of population that is named. To the extent possible,
individual unincorporated communities should be identified as separate CDPs.
2. A CDP is defined to provide data for a single named locality, therefore the Census Bureau does not
encourage delineating CDPs that comprise a combination of places or are identified by hyphenated
names. For example, CDPs such as Poplar-Cotton Center and Downieville-Lawson-Dumont are no
longer acceptable. Prior to Census 2000 communities were sometimes combined as a single CDP in
order to comply with the Census Bureau minimum population requirements. The Census Bureau’s
elimination of population threshold criteria has made such combinations unnecessary.
3. Multiple communities may only be combined to form a single CDP when the identities of these
communities have become so intertwined that the communities are commonly perceived and
referenced as a single place.
4. Multiple communities also may be defined as a single CDP when there is no distinguishable or
suitable feature in the landscape that can be used as a boundary between the communities, even if the
two communities still have separate identities.
5. There is no minimum population or housing unit thresholds for defining CDPs; however, a CDP
must contain some population or housing units or both. Participants submitting boundaries for
places with less than ten housing units may be asked to provide additional information attesting to
the existence of the CDP.
6. CDP boundaries should follow visible features, except in those circumstances when a CDP’s
boundary is coincident with the nonvisible boundary of a state, county, MCD, or incorporated place.

28

CDP boundaries may follow other nonvisible features in instances where reliance upon visible
features will result in over bounding of the CDP in order to include housing units on both sides of a
road or street feature. Such boundaries might include parcel boundaries and public land survey
system lines; fence lines; national, state, or local park boundaries; ridgelines; or drainage ditches.
7. The CDP name should be one that is recognized and used in daily communication by the residents of
the community.
8. A CDP should have population during at least one entire season of the year, and have a higher
housing unit and population density than surrounding areas.

In the following scenario a new CDP is created for the unincorporated community of Forks. The
unincorporated community of Forks on an AIR is labeled in the image below.

A new CDP is added to the shapefile with the TSAP Geography
tool (left image). Census Designated Places and All are
Manager
selected respectively as the work layer and update type. After
choosing New District for the current work district, the New District
Parameters window pops-up (see first image next page).

29

In the New District Parameters window, Forks is typed as the CDP name.

To begin a new CDP, area must be added to the project with the Assign Geography
tool. A new
CDP is initially an empty record and requires the addition of census blocks before it will be visible in
the view. A potential delineation for the Forks CDP is symbolized by a heavy green outline and green
stipple fill pattern in the image below.

Many tribes have population living in a community with a locally recognizable name outside the
boundary of their reservation. To define CDPs off your AIR/ORTL, please contact your RCC who will
help you coordinate with the appropriate Participant Statistical Area Program (PSAP) participant.

30

Working with existing CDPs
For CDPs delineated in prior decades, you may modify the name or revise the boundary. Name changes
are processed through the CDP component of the QC Tool (please refer to section 8.0), so even if no
geographic area changes are made, the QC Tool provides a function to review and modify CDP names.
The boundaries of CDPs are modified using the Assign
and Unassign
Geography tools, as
covered in the earlier “Using the Extension” section. However, if you select a block to assign to a CDP
that is already part of another CDP or incorporated place a message box will appear to notify you (see
image below).

If you do in fact intend to include a portion of an existing CDP into your new CDP delineation, select
Yes. Please report to your RCC if this situation occurs (see Appendix 5 to find your RCC’s contact
information).

5.4 Delineating Alaska Native village statistical areas (ANVSAs)
An ANVSA is a statistical area that represents the relatively densely settled portion of an Alaska Native
village (ANV). These are areas where residents of the defining ANV reside during at least one season
of the year, and include housing, cultural, and commercial structures. Members of the defining ANV
should also represent a significant proportion of the population of the ANVSA. ANVSAs are not meant
to portray large unpopulated areas or the full extent of traditional lands, and their delineation is not
intended to convey any rights to land ownership, governmental authority, or jurisdictional status.
ANVSA Criteria and Guidelines
The criteria for ANVSAs are:
1.
2.
3.
4.

ANVSAs delineated for the 2010 Census shall not overlap.
An ANVSA shall not completely surround the location of another ANV.
All portions of an ANVSA must be located within fifty miles of the ANV’s point location.
An ANVSA shall not include more water area than land area. Large expanses of water area should
be included only to maintain contiguity, to provide a generalized version of the shoreline, or if the
water area is completely surrounded by land area included in the ANVSA.
5. The name for an ANV must match the name corresponding to the ANV point location. Name
changes will only be considered if submitted in writing and signed by the highest elected official of
the ANV.
Guidelines for delineating ANVSAs are:
1. Housing units occupied by Alaska Natives, even if seasonal, should constitute the majority of
housing units within an ANVSA.
2. The population within an ANVSA should be majority Alaska Native and of that population, the
majority should be members of our population served by the delineating ANV.
3. ANVSAs should be located in areas of historical and traditional significance and include land that is
locally recognized as being associated with the village or group. In addition each ANVSA should
include land area that contains structures such as tribal headquarters, meeting areas, cultural or
spiritual landmarks, service centers and/or tribally owned stores.
4. An ANVSA should not extend beyond the regional boundary of the ANRC in which the ANV is
located (ANRC boundary shapefiles are included on the CD).
5. An ANVSA should not exceed 325 square miles in area. Based on review of ANVSA boundaries
from previous censuses as well as other information about ANVs and ANVSAs, the Census Bureau
suggests this size as sufficient to encompass the Alaska Native population and housing associated
with each respective ANVSA, but not so extensive that large amounts of non-Native population and
housing are included.
6. An ANVSA should not contain large areas without housing or population. Specifically, an ANVSA
should have a housing unit density of at least three housing units per square mile.
7. An ANVSA should be contiguous; that is, an ANVSA should form a single area with all territory
located within a continuous boundary. This makes identification of the extent of the ANVSA easier
for residents and data users, and also provides for a clearer representation of the ANVSA’s

32

boundaries on maps. An ANVSA, however, may be defined with multiple noncontiguous pieces if
doing so helps avoid inclusion of population and housing not associated with the ANV.
8. An ANVSA’s boundary shall follow visible, physical features, such as rivers, streams, shorelines,
roads, trails, and ridgelines.
9. Officials delineating ANVSAs may use nonvisible lines as an ANVSA boundary only if acceptable
boundary features are not available. For example, an ANVSA boundary may follow the nonvisible,
legally defined boundaries of ANRCs, boroughs, or cities.
10. If the ANVSA boundary follows a governmental unit boundary, the Census Bureau will adjust the
ANVSA boundary to continue to follow that boundary should it change due to correction,
annexation or detachment.
The process for delineating your ANVSA should begin with a review and inspection of the 2000 Census
ANVSA boundary (if an ANVSA was delineated in 2000) and the point location of your Alaska Native
village as well as the AIAN percent of total population of your ANVSA reported for the 2000 Census.
After opening the TSAP Geography Manager
tool, ANVSA and All are respectively selected as the
work layer and update type. In the example below, the fictional Alaska ANVSA has been chosen as the
current work district and its demographic data is listed beneath. Notice the extent and size of the census
blocks (light orange boundary lines) in relation to the 2000 Census ANVSA (transparent green fill). The
point location of the ANV is symbolized with a flag.

33

Utilizing the Toggle Block Symbology
tool, an additional perspective of the American Indian and
Alaska Native (AIAN) population per census block is displayed (see below image). Most noticeably the
2000 Census ANVSA boundary contains several large uninhabited census blocks covering both land
(areas in white) and adjacent water features. (The 2000 Census ANVSA boundary is symbolized with a
heavy green line.) An ANVSA with a total AIAN population percentage of 30% or greater is
recommended for statistical purposes.

An improved ANVSA boundary eliminates the large uninhabited census blocks and results in a more
spatially concise and accurate representation of the ANVSA’s population (see image below). The new
tool.
ANVSA boundary was achieved by removing census blocks with the Unassign Geography
Compare the new ANVSA boundary (visible by the green shaded area) with the 2000 Census ANVSA
boundary found on the previous page.

5.5 Delineating Oklahoma tribal statistical area (OTSA) tribal subdivisions
OTSA boundaries represent statistical entities identified and delineated by the Census Bureau in
consultation with federally recognized American Indian tribes that have no current AIR, but that had a
former AIR in Oklahoma. The boundary of an OTSA is that of the former AIR. Therefore, the Ceusns
Bureau does not expect any changes to OTSA boundaries. Upon review of your OTSA boundary if you
identify an error please contact the Kansas City RCC (see Appendix 5 for contact information).
OTSA and OTSA tribal subdivision Criteria and Standards
The criteria for OTSAs are:
1) An OTSA must contain some American Indian population and housing.
2) An OTSA may not overlap with any other AIA, at the same level of the geographic hierarchy.
3) An OTSA may not include more water area than land area.
4) OTSAs should be bounded by visible features such as roads, rivers, streams, shorelines, trails and
ridgelines.
5) The Census Bureau will evaluate the submitted name of each OTSA to ensure that the name is
clearly distinguishable from the name of any other OTSA.
6) OTSAs must be located completely within the current boundaries of the state of Oklahoma.
7) An OTSA may not completely surround another legal or statistical area at the same level of the
geographic hierarchy.
8) The name for each OTSA is determined by the tribe or tribes (in conjunction with the Census
Bureau) that are responsible for delineating each OTSA. The Census Bureau will revise any name
submitted for a geographic entity if it is determined that the criteria listed below were not applied
properly. The name of an OTSA must reflect one or more of the following conditions
a) The tribe or tribes associated with the former AIR represented by the OTSA;
b) Tribes that have historically resided within the area of the OTSA;
c) Tribes that have significant population currently residing within the OTSA; and/or
d) The name(s) of the tribe(s) commonly associated with the area encompassed by the OTSA.
Guidelines for delineating OTSAs are:
1. To the extent possible, OTSA boundaries identified for the 2010 Census should be the same as those
delineated for Census 2000.
2. OTSAs should follow the last legal boundaries established for their former AIR.
3. Tribes should strive to eliminate overlapping OTSA boundaries that resulted in the Census 2000
joint use area OTSAs.
4. Tribes may delineate tribal subdivisions within their own OTSAs.
5. Tribes may delineate CDPs representing unincorporated communities located within their own
OTSAs.
Guidelines for delineating OTSA Tribal Subdivisions are:
1. A Tribal subdivisions should represent units of self-government or administration within an AIR or
ORTL for a federally recognized tribe.

35

2. OTSA Tribal subdivisions are intended to completely cover all of an AIR and/or ORTL, or OTSA,
or at least the major contiguous portion of an AIR, ORTL, or OTSA.
3. The name of each tribal subdivision must reflect its name, as cited in recent tribal legal
documentation and/or used by the tribal government for administrative purposes.
4. If an OTSA consists of multiple, noncontiguous parts, the tribal subdivisions within them will be
noncontiguous.
OTSA tribal subdivisions are statistical entities that represent internal units of self government or
administration. Internal units may include areas that serve social, cultural, and/or legal purposes for a
tribal government. Please report the lowest level of administrative units that are available. For example,
if the tribe uses several levels of nesting geography, such as tribal council management districts that
wholly contain grazing districts, the grazing districts should be reported to the Census Bureau as the
tribal subdivision boundaries, as they are the smallest and lowest level of units used in that hierarchy. If
a similar hierarchical structure exists within the governmental units being reported as tribal subdivisions,
please delineate the lowest level unit in the steps below.
Working with existing OTSA tribal subdivisions
Existing OTSA tribal subdivisions should be reviewed and adjusted as needed. The Assign geography
tool , Unassign geography tool , and Merge tool
,all found on the TSAP Tools toolbar and
explained in section 6.0 Using the Extension, will be useful in census block based adjustments to your
OTSA tribal subdivision delineations.
Creating new OTSA tribal subdivisions
In the following example new OTSA tribal subdivisions are developed upon existing county boundaries
tool. The image below contains the spatial
and 2000 Census blocks with the Assign geography
extent of the two counties which will serve as building units for delineating new OTSA tribal
subdivisions.

36

Using the TSAP Geography Manager
tool select OTSA Tribal Subdivision as the current work layer
to begin the delineation process. You will immediately be prompted with the New District Parameters
window to identify your new OTSA tribal subdivision (see image below). A Tribal Subdivision Name is
typed in the text box provided.

The name of the new district will then be displayed as the current work district in the TSAP Geography
(see below left image). The Assign Geography
tool may be used to assign area by
Manager
county boundary or 2000 Census block. By default the Assign Geography
tool is set to use 2000
Census blocks for assignment. If you prefer to use county boundaries be certain to check the Use
Counties to Assign OTSA Subdivisions option box in the the TSAP Geography Manager .
In the example below the area from OK County 1 has been assigned to District 1 using the Assign
tool. Notice that the Use Counties to Assign OTSA Subdivisions option box has been
Geography
checked so that the area of OK County 1 was assigned to District 1 with a single click.

37

A second OTSA Tribal Subdivision is created by selecting New District as the current work district (see
below left image). Again, the New District Parameters window will appear prompting you to enter a
name for the new district (see below right image). Please enter the full administrative name of the
subdivision. For example, if the Tribal Subdivision is referred to as District 2 in official tribal
documentation, please type in District 2.

When switching to another work district be certain the current work district in the TSAP Geography
Manager
is correctly selected (see below left image). The area of OK County 2 is added to District 2
with the Assign Geography
tool (see below right image).

38

A third district, not based upon county boundaries, but upon 2000 Census blocks is added to finish this
OTSA tribal subdivision example. Following the directions for creating a new work district explained
above, District 3 is created. After checking off the Use Counties to Assign OTSA Subdivisions option
box - so that area will be assigned by 2000 Census blocks - the Assign Geography
tool is used with a
marquee selection (see below right image).

39

5.6 Delineating Tribal Designated Statistical Areas (TDSAs)
A TDSA is a statistical geographic entity identified and delineated by a federally recognized American
Indian tribe that does not currently have a reservation and/or off-reservation trust land. A TDSA is
intended to be comparable to the AIRs within the same state or region, especially those for tribes that are
of similar size. Your TDSA should encompass a compact and contiguous area that contains a
concentration of individuals who identify with your American Indian tribe and within which there is
structured, organized tribal activity. Criteria and guidelines for TDSAs are listed below:
TDSA Criteria and Guidelines
The criteria for TDSAs are:
1. A TDSA must contain some American Indian population and housing.
2. A TDSA may not overlap with any other AIA, at the same level of the geographic hierarchy.
3. A TDSA may not completely surround another legal or statistical AIA at the same level of the
geographic hierarchy.
4. A TDSA may not include more water area than land area.
5. Officials delineating TDSAs may only add nonvisible lines as a boundary if other acceptable
boundary features such as roads, rivers, streams, shorelines, trails and ridgelines, are not available
and they aid in a TDSA meeting other specific, delineation criteria and/or guidelines.
6. TDSAs may not include military areas.
7. TDSAs may not be delineated in Hawaii, Oklahoma or Alaska, nor will those existing in Alaska
continue to be recognized.
8. The name of a TDSA will be determined by the tribe or tribes, in conjunction with the Census
Bureau. The Census Bureau will evaluate the submitted name to ensure that each TDSA name is
clearly distinguishable from the name of any other legal or statistical AIA. The name must also
reflect one of two conditions: the tribe that has the largest population currently residing within the
TDSA, or the name of the tribe most commonly associated with the area that the TDSA
encompasses.
Guidelines for delineating TDSAs are:
1. TDSAs should be comparable in area to the AIRs and/or ORTLs of other tribes with similar numbers
of members in the same state and/or region.
2. American Indians should constitute a large proportion of the population within a TDSA, and of the
American Indian population, the majority should be members of the delineating tribe.
3. As a minimum, TDSAs should have a population of 1,200 individuals or 480 housing units.
4. A TDSA should include an area where there is structured and organized tribal activity, including
tribal headquarters, tribal service centers, meeting areas and buildings, ceremonial grounds, tribally
owned commercial locations, etc.
5. TDSAs should not contain large areas without housing or population. A housing unit density of at
least three housing units per square mile is suggested.
6. TDSAs should be contiguous.
7. Water area should be included only to maintain contiguity, to provide a generalized version of the
shoreline, or if the water area is completely surrounded by land area included in the TDSA.

40

8. TDSA boundaries should follow visible, physical features, such as rivers, streams, shorelines, roads,
and ridgelines.
9. TDSA boundaries may follow the nonvisible, legally defined boundaries of AIRs, ORTLs, states,
counties, or incorporated places.

The delineation process begins with the selection of TDSA as the
current work layer in the TSAP Geography Manager . After the
update type of All is selected the current work district will
automatically display the four digit census code for your area (see
right image).

After locating the general area for which you are considering your TDSA delineation, it is recommended
that you review the existing census block data. Using the Toggle Block Symbology
tool, activate the
AIAN percent of total population symbology. This will allow you to identify the blocks with a 30% or
greater AIAN percent of the total population. In the example pictured below a distinct pattern of census
blocks with a 30% or higher AIAN population is visible. A TDSA with a total AIAN population
percentage of 30% or greater is recommended.

41

In this scenario a new TDSA is delineated with the Assign Geography tool by clicking once on each
block that will comprise the TDSA. The finalized TDSA delineation is displayed in the image below
(census blocks are shown with default symbology).

42

5.7 Delineating State Designated Tribal Statistical Areas (SDTSAs)
Called SDAISAs in Census 2000, SDTSAs are created to provide state-recognized American Indian
tribes without an AIR, statistical data similar to that provided to tribes with AIRs. The entity
terminology changed to adhere more closely to the similar federal tribe naming convention, tribal
designated statistical area. SDTSAs are identified and delineated for the Census Bureau by a governorappointed state liaison, working in conjunction with tribal officials through the TSAP. SDTSAs
generally encompass a compact and contiguous area in which there is structured or organized tribal
activity and a concentration of individuals who identify with a state-recognized American Indian tribe.
As part of the 2010 Census, TSAP state liaisons representing state recognized tribe officials will again
have the opportunity to review and update the boundaries of existing SDTSAs (SDAISAs) or delineate
new SDTSAs.
The definition of a SDTSA may not necessarily include all tribal members; nor is it intended to depict
land ownership, represent an area over which a tribe has any form of governmental authority or
jurisdiction, or represent all of the traditional or historical areas associated with the tribe, including areas
used for subsistence activities. Representation of statistical American Indian Area (AIA) boundaries in
Census Bureau products is solely for the purpose of data tabulation and presentation. Likewise,
representation of SDTSA boundaries in Census Bureau products does not convey or confer any rights to
land ownership, government authority, or jurisdictional status.
SDTSA Criteria and Guidelines
The criteria for SDTSAs are:
1. A SDTSA must contain some American Indian population and housing.
2. A SDTSA may not overlap with any other AIA, at the same level of the geographic hierarchy.
3. A SDTSA may not completely surround another legal or statistical AIA at the same level of the
geographic hierarchy.
4. A SDTSA may not include more water area than land area.
5. Officials delineating SDTSAs may only add nonvisible lines such as corporate limits as a boundary
if other acceptable boundary features such as roads, rivers, streams, shorelines, trails and ridgelines,
are not available and they aid in a SDTSA meeting other specific, delineation criteria and/or
guidelines.
6. SDTSAs may not include military areas.
7. An SDTSA for a specific tribe may be delineated in a state only if the tribe is officially recognized
by the state.
8. The name for each SDTSA is determined by the tribe or tribes (in conjunction with the Census
Bureau, and the state liaison for SDTSAs) that are responsible for its delineation. The Census
Bureau will evaluate the submitted name to ensure that each SDTSAs name is clearly distinguishable
from the name of any other legal or statistical AIA. The name of a SDTSA must reflect one or more
of the following conditions: The tribe that has the largest population currently residing within the
SDTSA; and/or the name of the tribe most commonly associated with the area encompassed by the
SDTSA.

43

Guidelines for delineating SDTSAs are:
1. SDTSAs should be comparable in area to the AIRs and/or ORTLs of other tribes with similar
numbers of members in the same state and/or region.
2. American Indians should constitute a large proportion of the population within a SDTSA, and of the
American Indian population, the majority should be members of the delineating tribe.
3. A minimum population of at least 1,200 individuals or 480 housing units is suggested to help
enhance reliability and availability of sample-based data.
4. SDTSAs should include area where there is structured and organized tribal activity, including tribal
headquarters, tribal service centers, meeting areas and buildings, ceremonial grounds, tribally owned
commercial locations, etc.
5. SDTSAs should not contain large areas without housing or population. A housing unit density of at
least three housing units per square mile is suggested.
6. SDTSAs should be contiguous.
7. Water area should be included only to maintain contiguity, to provide a generalized version of the
shoreline, or if the water area is completely surrounded by land area included in the SDTSA.
8. SDTSA boundaries should follow visible, physical features, such as rivers, streams, shorelines, roads,
and ridgelines.
9. SDTSA boundaries may follow the non visible, legally defined boundaries of AIRs, ORTLs, states,
counties, or incorporated places.

The delineation process begins by selecting the SDTSA as the current
work layer in the TSAP Geography Manager . After the update
type of All is selected the current work district will automatically
display the four digit census code for your area (see right image). As
in the example image, population and housing unit data will be blank
when delineating a completely new SDTSA.

After locating the general area for which you are considering your SDTSA delineation, it is
recommended that you review the existing census block geography. Using the Toggle Block Symbology
tool, activate the AIAN percent of total population symbology. This will allow you to identify the
blocks with a 30% or greater AIAN percent of the total population.

44

In the example image below a distinct pattern of census blocks with a 30% or higher AIAN population is
visible. An SDTSA with a total AIAN population percentage of 30% or greater is recommended.

In this scenario a new SDTSA is delineated with the Assign
Geography tool by clicking once on each
block that will comprise the SDTSA. The finalized SDTSA delineation is displayed in the image below
(census blocks are shown with default symbology).

45

5.8 Delineating State American Indian Reservations
State American Indian reservations (state AIRs) are reviewed and updated as needed once before each
decennial census to ensure a complete inventory of state AIRs for those states with state-recognized
tribes that are not also federally recognized. The review should determine, solely for data collection and
tabulation by the Census Bureau, the complete and current inventory and the correct attributes (names,
legal descriptions, official status) and official, legal boundaries of the state AIRs in each state. The
Census Bureau also accepts additions and updates to features such as roads or rivers that serve as the
boundary of the state AIR, as well as address range break information at the boundaries.
For affected states, a governor appointed state liaison provides the name, boundary, and any associated
updates for each state recognized AIR to the Census Bureau. If the state AIR official declines or defers
participation, the Census Bureau will use the Census 2000 state AIR boundaries, to tabulate 2010
Census data.
State Reservation Criteria and Guidelines
State AIR boundaries and names should be reported to the Census Bureau as they exist in the legislation
or treaty under which they were established. By definition, state AIR boundaries cannot cross state lines
unless the AIR and tribe is separately recognized in each state. State AIRs may not include territory
within federally recognized AIRs or ORTLs. Acceptance of boundary changes to state AIRs requires
clear legal documentation supporting any, and all, changes involving these boundaries. The Census
Bureau will identify each state AIR with the name submitted by the state liaison providing the boundary
for the area. For this reason, the state AIR name should reflect the specific tribal name cited in the legal
records establishing the state AIR.

In the following example delineation scenario an existing state AIR
boundary is updated to include additional legally defined land. The
delineation process begins with the selection of STRES as the current
work layer in the TSAP Geography Manager . After the update
type of All is selected the current work district will automatically
display the name of the state AIR to be delineated (see right image).

46

Next the spatial extent of the state AIR and existing census block geography are reviewed. The existing
state AIR (light green fill) and census blocks (heavy orange lines) are pictured below.

Upon comparing the Census Bureau’s depiction of the state reservation boundary to a reliable state
document a difference is noted. In some cases the area that needs to be added may be a whole block and
you can use the Assign geography tool to accomplish the task. In this example, it is apparent that a
new line must be added to correctly depict the state AIR boundary. This is accomplished by starting a
line edit session with the Census Editing Tools toolbar (see below image).

Once the edit session is active, use the Sketch tool
page).

to add your new line feature (see first image next

47

After completing the new line feature with a double click, the Update Line Attributes message box will
pop-up (see below image). The default Classification is the Nonvisible Legal/Statistical Boundary type;
other types may be found in the pull down menu. OK is clicked once to continue.

After choosing a Classification type, the Split Block Attributes window appears offering an opportunity
to utilize local knowledge while assigning population to the new blocks (see below image).

48

The new area is pictured in the below image.

After ending the line edit session, the new area must be assigned to the state AIR boundary with the
Assign geography
tool. The completed state AIR boundary update is pictured below.

When adding a boundary that is within 30 feet (10 meters) of an existing line in the Census Bureau’s
shapefile do not add an additional line. Instead use the existing line features wherever possible.

49

6.0 Using the Extension
The TSAP Extension features tools and commands useful in the identification, delineation, and review
of your statistical areas. This section presents details on how these tools/commands can be used to
accomplish the core tasks of the mapping process. The administrative Geography Manager and
Workflow Manager are presented first, followed by editing tools, and the quality control tools.
6.1 TSAP Geography Manager
The TSAP Geography Manager tool allows you to identify and select with pull-down menus a work
layer, update type, and work district. A work layer specifies the entity type you will be delineating, for
example: tribal census tracts, Alaska Native village statistical areas, census designated places, etc. A
work district further specifies a particular feature of the work layer such as an individual tribal census
tract. The update type menu allows you to narrow your work districts to those features above or below
population and/or housing unit thresholds (applicable only when working with tribal census tracts, tribal
block groups, and census designated places). The TSAP Geography Manager is activated by clicking
once on the Show/Hide TSAP Geography Manager
button in the TSAP Management toolbar. In the
series of example images below a work layer, update type, and work district is selected. In the final
image notice the demographic data visible once a work district is selected.

TOOL TIP
Hold down the Ctrl key and
click on an area to change the
Current Work District
selection

50

6.2 Workflow Manager
The Workflow Manager presents an outline of the major tasks associated with delineating your statistical
areas and offers a tool for you to monitor the progress of your project work. It is activated by clicking
once on the Show/Hide Workflow Manager
button on the TSAP Management Toolbar. Before your
project is started the manager will appear blank as shown in the below left image. As you work through
your project, review and delineation tasks will automatically become checked as they are completed.
For example, after you start a project and the necessary datasets are assembled, the Data Setup task will
become checked (see below right image).
Once your project is setup the Workflow Manager will display the area types eligible for delineation as
determined by your tribe’s delineation eligibility (see Table 1, section 2 or Appendix 1). In the example
shown in the below right image, the tribal participant is eligible to delineate tribal tracts, tribal block
groups, and CDPs. Therefore all other area types are grayed out and disabled.

51

6.3 Working with Census blocks
The census block is the smallest unit of census geography. The TSAP extension makes use of existing
census block geography generated from the 2000 Census. Census 2000 block geography is provided for
reference in your delineations because it is the most recent area representation of population and housing
unit counts available. Following the completion of the TSAP statistical area delineations for the 2010
Census, the Census Bureau will generate an entirely new set of block boundaries that will nest within the
statistical areas you delineate. It is the newly generated block boundaries that will be the most accurate
representation of your area’s 2010 Census population.
Several of the tools described later in this section present methods used to assign and unassign blocks to
an entity, as well as methods of splitting blocks. However, it is important to understand which blocks
you may want to include or exclude from your area or to modify for your delineations, as based upon the
Census 2000 American Indian Alaska Native (AIAN) percent of total population. The Toggle Block
Symbology
tool, found in the TSAP Management toolbar, is intended to aid you in this process. The
default block symbology is a heavy orange outline (see below left image). Click once on the Toggle
button and the block symbology will switch to a graduated color fill corresponding
Block Symbology
to the AIAN percent of total Census 2000 population for each block (see lower right image). In the
Table of Contents, you will also notice that the legend switches as shown in the below images. Blocks
without population will appear without a fill color or boundary when in the AIAN percent of total
population symbology. Click the Toggle Block Symbology
button again to return to the default block
symbology.

6.4 Assigning and unassigning geography to and from your area
The Assign
and Unassign
Geography tools in the TSAP Tools toolbar allow you to spatially add
and subtract Census 2000 blocks to/from your statistical areas. In the following example many blocks
are assigned to tract 1490T00100 using a marquee selection. First the Assign Geography
button is
clicked once, making the tool active (you will notice a modified cursor when the tool is active). The
cursor is then clicked and dragged over the blocks to be assigned. Blocks may also be selected
individually by clicking once directly on the block you wish to assign. It is highly encouraged to assign
blocks rather than unassign blocks when delineating your statistical areas however the Unassign
Geography
tool may be used when necessary. Using the Unassign Geography
tool does not
reassign blocks to another feature but rather removes the blocks entirely from any feature. This process
could result in unassigned areas that will be caught and corrected in the QC process.

TOOL TIP
More than one block can be assigned or unassigned at one time. Use a standard rectangular marquee selection or
while holding down the Shift key freehand sketch a polygon that contains the blocks you wish to assign or
unassign.

53

6.5 Splitting tribal census tracts and tribal block groups by block selection (applies only to Federally
recognized tribes with AIRs/ORTLs)
Splitting tribal census tracts and tribal block groups is a convenient method for creating new tribal
census tracts and tribal block groups. The TSAP Tools toolbar offers a unique solution with the Split by
block selection tool . This tool is activated by clicking once on the Split by block selection tool
button. Once the tool is active, click and drag the crosshair cursor over the Census 2000 blocks of
interest to make a block selection. In the left image below a rectangular marquee selection has been
made to split a block group. The right image displays the selected blocks (highlighted in blue).

If your block selection is complete, double
click anywhere to continue the split
process. A message window (shown
below) will prompt you to confirm your
block selection. After clicking Yes, the
existing block group is split yielding a new
tract (see right image).

54

6.6 Splitting blocks with existing line features
Blocks are most often defined by visible linear features such as roads, shorelines, rivers, power lines, et
cetera, as well as by governmental unit boundaries that are frequently not visible features. When
working with the Census 2000 blocks you may find the need to split blocks to accommodate your
statistical area delineations. Splitting Census 2000 blocks is also considered an opportunity to suggest
Census 2010 block boundaries that upon review may be utilized by the Census Bureau when generating
the new 2010 block boundaries.
The Census Editing Tools toolbar offers unique line editing tools to accomplish the process of splitting
Census 2000 blocks with existing line features (as found in the Line Features Group Layer in your
ArcMap project). If a linear feature is not represented in the dataset you may also sketch in that feature
using the line editing tools. You may also need to add a feature extension or a new line if an existing
line feature does not entirely split a block. This will be covered in the next section, Splitting blocks with
new line features.

Begin the block splitting process by clicking on the Line Edit Menu pull down of the Census Editing
Tools toolbar and selecting the Start Line Editing command (see image above). If ArcMap’s Editor
toolbar is already in use, the Target layer pull-down menu may be found there rather than the Census
Editing Tools toolbar. If your project contains more than one county, be certain that your Target Layer
is the edge shapefile for the correct county.

55

Line features that will be used to split the block are selected with the Select Features tool
example, Mifflin Ditch has been selected to split block 1002 (see image below).

. In this

With the line features selected, click once on the Split Block Tool
button. A Split Block Attributes
window (see image below) will pop-up containing the tabulated total population, housing units, and
American Indian Alaska Native (AIAN) population for the two blocks generated by the split block
operation. The tabulated statistical data contained within the window is based upon 2000 Census data
and automatically calculated by area. Use the Highlight Part 1 and Highlight Part 2 buttons to spatially
identify the two new blocks. Local knowledge may be used to adjust the new blocks’ population,
housing units, and AIAN population by clicking inside the cell of interest and typing. Notice the data
cells of the other block will adjust automatically as you change the population values in the Split Block
Attributes window.

After the data cells have been adjusted as needed, OK is clicked to proceed and finalize the block
splitting process.

56

The two new blocks and the block boundary are now visible and symbolized appropriately. Because
you are not actually changing Census 2000 blocks but rather beginning to define Census 2010 blocks,
the block labels will remain the same (i.e. the two resulting blocks have the same label).

When finished splitting blocks, deactivate the line edit session and save your work by selecting Stop
Line Editing in the Line Edit Menu (see image below). A message window will then appear prompting
you to save or cancel your changes.

57

6.7 Splitting blocks with new line features
In the following example, block 1002 will be split using the Mifflin Ditch because there is a desire to
make the ditch a block group boundary. However unlike the previous section, in this example the
Mifflin Ditch line feature does not completely cross the entire block. While it is recommended that
existing features be used to split blocks, small “feature extensions” may be added to complete the
splitting line feature. Such feature extensions may follow lines of sight or convenience when no other
feature is available to better enclose an area. The feature extension added in this example connects
Mifflin Ditch to Conrail Railroad. If possible, “feature extensions” should be no longer than 300 feet in
length. The Census Bureau also wishes to stress that line feature additions will be accepted through the
TSAP only if they serve as boundaries. Feature extensions are not permitted to connect to non visible
boundaries.
When adding a boundary that is within 30 feet (10 meters) of an existing line in the Census Bureau’s
shapefile do not add an additional line. Instead use the existing line features wherever possible.
The block splitting process is begun by clicking on the Line Edit Menu pull down of the Census Editing
Tools toolbar and selecting the Start Line Editing command (see image below).

After the line editing toolbar is activated make certain the correct line features shapefile is the Target
layer. If ArcMap’s Editor toolbar is already in use, the Target layer pull-down menu may be found
there rather than the Census Editing Tools toolbar.

58

Because in this example, Mifflin Ditch does not entirely cross block 1002, it is necessary to add a
feature extension from the end of Mifflin Ditch to Conrail Railroad, a visible feature. A feature
extension is added by first clicking on the Sketch Tool
button. Once activated, the Sketch Tool cursor
is located over the end of the Mifflin Ditch and clicked once to begin the line. Be sure to zoom in very
close to make sure the new feature snaps properly to the existing feature both at the start and end of the
line. All subsequent vertices are added by single clicks. The feature extension is ended with a double
click. Again, zoom in to make sure the end properly snaps to the existing features.
TOOL TIP 
The snap tolerance when 
adding a line feature is 
10 feet.  When starting 
or beginning a line be 
sure to zoom in close 
enough that you sense 
the snap tolerance. 

Hold down the z key to 
zoom in and hold down 
the x key to zoom out 
while the sketching tool 
is active. 

After the feature extension is ended, a line attributes window will pop-up (see image below). In the
Classification pull-down the type is selected. The default class for new line features is P0001 –
Nonvisible Legal/Statistical Boundary. If a line feature is being added that represents an actual visible
physical feature, please select the appropriate class code. A full name is required for road features only,
but is recommended for all new features. Address ranges may be optionally included by State
Reservation Program participants when adding new street features that intersect the boundary of their
reservation.

59

Next, all line features that will be used to split the block are selected with the Select Features tool .
In this example, Mifflin Ditch and the new feature extension line have been selected (see image below).

button. A Split Block Attributes
With the line features selected, click once on the Split Block Tool
window (see image below) will pop-up containing the tabulated total population, housing units, and
AIAN population for the two blocks generated by the split block operation. The tabulated statistical
data contained within the window is based upon 2000 Census data and automatically calculated by area.
Use the Highlight Part 1 and Highlight Part 2 buttons to spatially identify the two new blocks. Local
knowledge may be used to adjust the split blocks population, housing units, and AIAN population by
clicking inside the cell of interest and typing. Notice the data cells of the other block will adjust
automatically.

After the data cells have been adjusted as needed, OK is clicked to proceed and finalize the block split
process.

60

The two new blocks and the block boundary are now visible and symbolized appropriately. Because
you are not actually changing Census 2000 blocks but rather beginning to define Census 2010 blocks,
the block labels will remain the same (i.e. the two resulting blocks have the same label).

When finished splitting blocks deactivate the line edit session and save your work by selecting Stop Line
Editing in the Line Edit Menu. A message window will then appear prompting you to save or cancel
your changes.

61

6.8 Line attributes tool
The attributes of individual line segments may be updated with the Line attributes tool , including the
name, type of feature (i.e. classification), address range and ZIP code range (optional for State
Reservation Program participants adding street features). The tool is activated by clicking once on the
Line attributes tool
button included in the Census Editing Tools toolbar. The tool’s selection cursor
is then located over the line feature to be updated and clicked once. In the example below, Ash Street is
being selected.

Once a line feature has been selected the Update Line Attributes window will pop-up displaying the
existing attributes for Ash Street (image below).

62

The classification is changed by selecting a type from the pull-down menu. A name for the feature is
added in the Full Name text box. In the example below, Ash Street has been updated to an alley named
Old Ash Alley (see image below).

After clicking OK, to confirm the line attribute update, your changes will take effect immediately.
Notice the new label for Old Ash Alley in the example image below.

63

6.9 Merging tracts and block groups
The Merge Tool
included in the TSAP Tools toolbar is used to combine two tribal census tract or
tribal block group features. In the example below two tribal census tracts, 4760T00201 and
4760T00202, that were originally split from the same tract (as identified by the T002 tract code and their
two character suffixes) will be merged to reform one new tribal census tract. The merge function is
activated by clicking once on the Merge Tool
button. The crosshair cursor is then positioned over
one of the two tracts and clicked once selecting the first feature (see below right image).

The selection process is then repeated for the second feature to be merged. After the second selection a
message window will pop-up to confirm or cancel the merge process.

64

With the merge process complete a new tribal census tract with a new unique code is displayed (see
below image).

6.10 Updating type attributes for tribal tracts and tribal block groups
Tribal tracts and tribal block groups may contain features such as parks, schools, group quarters, water
features, etc. that influence or change the usefulness of statistical data being reported for your area. In
some cases it is useful to isolate these areas as special use tracts and block groups. In the event that
separate special use tracts or block groups are created to enhance your delineations, the Tract/BG type
found on the TSAP Tools Toolbar may be used to assign attribute types to those areas. The tool
tool
is activated by clicking once on the Tract/BG type tool
button. The cursor is then positioned over the
area of interest and clicked once. In the example below the cursor has been placed over block group
4160T00100B.

65

The Select Type pop-up window will appear following your selection (see below image). The ID field
will remain disabled and you will need to only select a type from the pull-down menu. In the example
below the P-Park type has been selected. Click OK to proceed and finish the process.

Special land use tribal census tracts and tribal block groups
To recognize and distinguish the special uses of some parcels of land, the Census Bureau allows for the
definition of special land use tribal census tracts or block groups. Specific areas such as ceremonial
grounds, historic sites, and parks can be identified as special land use tribal census tracts or tribal block
groups. These areas must have an official name, generally have little or no residential population or
housing units (or meet the non special land use tribal census tract or tribal block group population and
housing unit thresholds) and must be contiguous. If located in a densely populated urban area, a special
land use tribal census tract or tribal block group must have an area measurement of approximately 1
square mile or more. If delineated completely outside an urban area, a special land use tribal census
tract or tribal block group must have an area of approximately 10 square miles or more. Participants are
not required to delineate special land use tribal census tracts or tribal block groups.
The Census Bureau recognizes that some special land use areas not intended for residential population,
such as parks, may contain some population, such as caretakers or the homeless. Our intent is to allow
for the delineation of parks and other special land use areas as separate tribal census tracts and therefore
we will accept such areas as special land use tribal census tracts even if some, but very little, residential
population is present.

66

7.0 Block boundary definition
Each of the legal and statistical boundaries delineated as part of TSAP will be held as 2010 census block
boundaries. Many other features, such as roads, that form closed polygons with other features are also
planned to be held as 2010 block boundaries by the Census Bureau. Other line features are either
ineligible to be 2010 block boundaries (most likely because they do not form a closed polygon with
other features) or are neither planned nor eligible to be held (unassigned). The block boundary
definition tool provides an opportunity for TSAP participants to identify features that are currently
unassigned or planned that they want the Census Bureau to recognize or hold as block boundaries for the
2010 Census. TSAP participants may also identify features they do not want held as block boundaries.
Below is a list of all the feature and boundary types that are currently already planned to be held as 2010
Census tabulation block boundaries and therefore do not need to be noted as suggested holds on the
paper maps. In some instances you may not want a feature to become a 2010 Census tabulation block
boundary such as where there are roads identified in our files as double lined roads. Due to recent
updates to our data, there are now many more roads identified as double line roads that, in the past, were
classified as single line roads. This causes the area in the middle (a median strip for example) to become
a long narrow block. If you do not want the polygon formed by the two road edges to be a separate
2010 Census tabulation block, you may want to consistently flag one of the edges with a “Do Not Hold.”
Note: If any other program sponsored by the Census Bureau uses that line as a boundary, the Census
Bureau will override the “Do Not Hold” status of the line.
Entities: The boundaries, as of January 1, 2010, for each of the entities listed below, are planned 2010
Census tabulation block boundaries and therefore do not have to be flagged as a 2010 block boundary.

The TSAP extension provides functionality to make block boundary definitions through the Block
Boundary Definition Tool
found on the TSAP Tools toolbar. In the following example, Lincoln
Street between 3rd and 4th streets is updated from a ‘planned hold boundary’ to a ‘do not hold boundary’
(see below image).

68

After activating the Block Boundary Definition Tool
the line features will turn to a block boundary
definition symbology. Lincoln Street is currently attributed as a Planned hold boundary (see right
image and legend below).

The update is accomplished by positioning the Block Boundary Definition Tool
cursor over the line
segments of interest and clicking once on each segment while holding down the Shift Key. The
symbology for the targeted line segments will immediately change to display Lincoln Street as a ‘do not
hold boundary’.

A single click on an eligible line feature will assign it as a Planned hold boundary. A single click while
pressing the Shift Key will identify a line feature as a Do not hold boundary. Double clicking anywhere
within the data frame will return the line features to their default symbology.

69

8.0 Quality Control and Name Changes
Participants should review their delineations before submitting them to the Census Bureau. The Census
Bureau will review each plan before it is accepted for use in the 2010 Census. Submissions will be
compared against published criteria and standards, and accepted on a case-by-case basis. Criteria checks,
such as population and housing unit thresholds, and minimizing geographically noncontiguous areas, are
included in the QC Tool
for participants to use before submittal. The QC Tool
also offers an
opportunity for participants to justify or explain delineations not meeting population and housing unit
thresholds as well as those areas that are noncontiguous. Justifications for not meeting criteria are found
in Appendix 2
Participants will be prompted to operate the QC Tool
after delineating each entity type. For example,
a participant trying to delineate a tribal block group before having run the QC Tool
on tribal census
tracts will be encouraged with a message box to complete the QC process for tribal census tracts before
continuing (see below image).

After clicking once on the QC Tool
button to activate the tool, the QC window will appear (see
below image). Although the following example scenario is for the QC of Tribal Tracts, the process
described and the accompanying screenshots are similar and applicable to the QC process for all TSAP
entities. When you need to make corrections to your delineations close the QC window and adjust
your shapefiles as necessary with the tools included in the TSAP Extension as presented in the
previous sections of this guidelines document.

70

As seen in the previous image, the queue of the QC window will be empty on first opening. Features
available for QC are identified by clicking the Show All button (see below image).

Features not meeting particular criteria will appear in the queue and may be sorted by clicking one of the
criteria buttons on the left side of the QC window. In the example image below, only the tracts falling
under the population threshold are identified by clicking the Below Population button.

71

To continue the QC process, individual tracts are selected from the queue with a single click. After
selection, unmet thresholds associated with the selected tract will become active in the right pane of the
QC window. Tract 4610T00600 is selected in the below image.

Unmet thresholds should be corrected or explained by either typing directly in or choosing a justification
from the combination text box/pull-down menu (justifications are listed in Appendix 2). After entering a
justification, the corresponding threshold button (e.g. in the above image the Below 1,200 Pop, Below
480 HUs buttons) must be pressed to accept the update and populate the attributes of the shapefile. (See
below image.)

TOOL TIP
Use the Zoom and scroll buttons to navigate through the features. The Zoom button will change the data frame to
the extent of the selected feature.

72

After a feature has been justified it will no longer be available from the queue for that particular
threshold (e.g. after accepting a Below 1,200 Pop justification, tract 4610T00600 will no longer appear
in the Below Population queue). Justifications may be reviewed by clicking the Show All button,
selecting the feature of interest, and clicking the View Justification button at the bottom of the QC
window. In the example below tract 4610T00600 is selected and the justification is visible.

Once the population and housing unit thresholds have undergone the QC checks, and have either been
corrected or justified, participants are encouraged to check their delineations for noncontiguous areas.
Noncontiguous areas are those entities which are comprised of several disconnected polygons (i.e.
multipart features in shapefiles). The noncontiguous area QC is activated by clicking on the
Noncontiguous button on the lower left of the QC window (as shown in the previous screenshots). After
activation, a Noncontiguous Parts pane appears on the left side of the QC window. Only one part per
feature needs justification.

73

A convenient tool for reviewing noncontiguous areas is the Zoom
tool. When reviewing
noncontiguous areas you will often find that some noncontiguous parts are not immediately visible on
screen. This is due to small census blocks that often occur at the intersection of line features such as non
visible boundaries, water features, and urban/developed areas. Clicking on the zoom button will allow
you to quickly locate those hard-to-see noncontiguous parts. Most noncontiguous parts should be
corrected by assigning them to the immediately adjacent statistical area.
After completing the noncontiguous areas portion of the QC process clicking the Show All button will
return the default QC window. The final component of the QC process involves identifying empty
shapefile records that may have resulted from the merging, splitting, and geographic assignment tasks
associated with delineating. Click the Show Empty Shapes button to identify these records and click the
Remove Empty Shapes button to delete these records from your shapefiles (the buttons are found in the
lower left corner of the QC window).
Upon completing the entire QC process the red Review button is clicked. Provided all QC is completed
correctly, the red Review button will become a green Complete button (see below image).

If the review is incomplete or incorrect a message box will pop-up identifying the threshold or criteria
still needing review (see example in bottom image).

TOOL TIP
and the Find Unassigned Areas Tool
both available on the TSAP
The Find Noncontiguous Areas Tool
Tools toolbar may be used outside of a formal QC Tool session to identify potential geography errors.

74

Name Changes
Aside from tribal census tracts and tribal block groups, all TSAP entities may submit name changes or
corrections. Name changes are accomplished during the QC process. The option to change an entity’s
name will be the first item in the QC Tool window for ANVSAs, OTSAs, CDPs, TDSAs, SDTSAs, and
State reservations. After typing in an updated name in the left justified text box click the Change Name
button to update your delineations. Examples of the QC Tool window for ANVSAs and CDPs with the
Change Name option visible are pictured below.
If you do choose to change the name of your tribal statistical area, the Census Bureau additionally
requests that you report your name change to the RCC (RCC contact information is found in
Appendix 5).

75

9.0 Submitting your data
Delineations are finalized and prepared for submission with the Submit Data Tool
on the TSAP
Management toolbar. This tool assembles and exports the necessary shapefiles into an Output directory
in your local workspace. The finalized delineations exported to the Output directory are the shapefiles
of your delineations that the Census Bureau will review before the verification phase of the 2010 Census.
Upon activating the Submit Data Tool
with a single click a
message box will immediately appear to confirm your submission
(see right image). After clicking Yes, the necessary shapefiles will
be assembled and exported to the Output directory that will reside
within the original workspace of your project. A second message
box will appear listing the local path name to your Output directory
(see below image). Please make note of the Workspace directory, as you need to navigate to it in the
next step in the submittal process.

At this point the TSAP Workflow Manager will appear similar to the below image.

76

An example Output directory is pictured below in Windows Explorer. It is recommended the Output
directory be compressed, or “zipped”, with a file compression utility before electronic submission to the
Census Bureau (see section 9.1).

77

9.1 Compressing the files for submittal
To prepare your files for submittal, please locate your work output folder, in this example:
C:\TSAPExtension\Data\Output folder and compress it into a single “zip” file, using the provided utility,
Freebyte Zip. The compression utility is located on the TSAP Data CD, and named “fbzpack.exe”.
Please do not use WinZip to compress the files, as some older versions of the program may corrupt
shapefiles.
To install fbzpack.exe, copy the file “fbzpack.exe” to the TSAPExtensionData directory, and doubleclick on the file to run the installation. You may get a pop up warning; please click “Run” (see image
below) to continue the installation.

At the next prompt, make sure all three files are highlighted and click “Start” to continue (see image
below).

78

Click OK to complete the installation.

To begin using the program and compress your output files for submittal, navigate to the FBZip.exe
program (below) and double-click.

After the Starting Freebyte ZIP program window appears, select Create a new ZIP archive (see image
below).

Select

79

You are then presented with a prompt to “Save new ZIP archive as” (below).

Navigate to the Workspace directory, noted previously and using your project’s entity code, name the
zip file TSAP and select Save (The entity code is the same as the Census Area Code
found in Tables A-D of Appendix 1: Table A. Federally Recognized Tribes, Table B. Alaska Native
Villages, Table C. Federally Recognized Tribes in Oklahoma with former American Indian reservation
in Oklahoma, Table D. State Recognized Tribes). You will then be prompted to “Add files or folders to
zip archive” (see image below).

Please make sure that your selections match the above image, then select Add folder.

80

You will then be prompted to add a directory to your archive (image below). Select the directory named
TSAP_Complete then click OK.

You should now transfer the resulting zip file to the Census Bureau using the instructions in the next
section.

9.2 Transferring your data to the Census Bureau
Submissions will be accepted via the Census Bureau’s Public File Send Utility (pictured on the next
page) found online at:
http://www2.census.gov/cgi-bin/sendfile
Use the following steps to send your files to us via the Public File Send Utility (see the following page
for a screenshot of the website):
1. Under Source Information (Local), click on the Browse button to navigate to your zip folder created
in the previous section containing your delineations (named TSAP_Complete).
2. In the Target Information (Remote) section, enter /geo/2010_PSAP_TSAP/ in the Directory to
Receive File.
3. Under the Notify by E-mail, type your e-mail address in the Sender’s E-mail Address. In the Census
Bureau Employee’s E-mail Address field enter [email protected].
4. Type in the Verification Code that you see in the box at the screen and click Upload to send your file.
Additional contact information for the Regional Census Center that will process your submission is
found in Appendix 5 of this document.

81

82

10.0 Verification
As long as a submission for TSAP is received by the Census Bureau within the 120 day schedule, each
participating tribe will be eligible for a verification phase. During verification, the Census Bureau
provides new materials to reflect how we inserted the submitted tribal statistical area delineations into
our database. The verification materials will be provided in late 2009. At that time, tribes may review
the new areas and as needed make minor boundary corrections. Digital participants will be provided
with shapefiles for their verification review process.

Appendix 3. Glossary of Terms
2010 Census tabulation blocks Blocks determined in October 2010 that will be used to tabulate the
data used to report the 2010 Census.
Alaska Native village statistical area (ANVSA) ANVSAs are statistical geographic entities
representing the residences, permanent and/or seasonal, for Alaska Native members of the defining
Alaska Native village (ANV) and that are located within the ANV’s historic/traditional region.
American Community Survey The American Community Survey is a Census Bureau survey that is
sent to a small percentage of our population on a rotating basis. It is also conducted in Puerto Rico,
where it is called the Puerto Rico Community Survey.
American FactFinder The Census Bureau's data website and search tool located at www.census.gov
(click on “American FactFinder” in the left menu).
American Indian off-reservation trust lands (ORTLs)American Indian trust land is an area for which
the United States holds title in trust for the benefit of an American Indian tribe or for an individual
American Indian. Trust land may be located on or off a reservation; however, the Census Bureau
recognizes and tabulates data only for off-reservation trust land. Census data always associates offreservation trust land with a specific federally recognized reservation and/or tribal government.
American Indian reservation (AIR) A federal American Indian reservation is an area that has been set
aside by the United States for the use of one or more federally recognized American Indian tribes. Its
boundary is defined by tribal treaty, agreement, executive or secretarial order, federal statute, or judicial
determination. The Census Bureau recognizes a federal reservation as territory over which a tribe(s) has
primary governmental authority. A state American Indian reservation is an area that a state government
has allocated to a tribe recognized by that state, but not by the federal government. American Indian
reservations are known as colonies, communities, Indian communities, Indian villages, pueblos,
rancherias, ranches, reservations, reserves, and villages.
Block Definition Project (BDP) The BDP provides an opportunity for tribes to review the features that
we plan to hold as 2010 tabulation block boundaries and to flag additional features that tribes wish to be
included as 2010 tabulation block boundaries.
Boundary and Annexation Survey (BAS) An annual survey conducted by the Census Bureau to
collect and maintain information on the inventory, status, boundaries, and names of all governmental
units.
Census Designated Place (CDP) CDPs represent locally-known, unincorporated communities that
contain a mix of residential, commercial, cultural, and/or retail uses similar to that of an incorporated
place of similar size in a similar geographic setting.
Feature A group of connected line segments with the same primary name and classification.

125

Feature extension A nonvisible line from the end of a road that extends at an angle of 180 degrees and
is no longer than 300 feet in length and connects the road to a non-road feature.
Federal Information Processing Standards (FIPS) code Codes that are assigned for a variety of
geographic entities, including American Indian area, Alaska Native area, Hawaiian home land,
congressional district, county, county subdivision, metropolitan area, place, and state. The objective of
FIPS codes is to improve the ability to use the data resources of the federal government and avoid
unnecessary duplication and incompatibilities in the collection, processing, and dissemination of data.
Geographic Areas Branch (GAB) The branch in the Census Bureau’s Geography Division responsible
for managing the geographic components of the Tribal Statistical Areas Program.
Geographic Information System (GIS) A collection of computer hardware, software, and geographic
data for capturing, managing, analyzing, and displaying all forms of geographically referenced
information.
Incorporated place A type of governmental unit, incorporated under state law as a city, town (except in
New England, New York, and Wisconsin), borough (except in Alaska and New York), or village,
generally to provide specific governmental services for a concentration of people within legally
prescribed boundaries.
Minor civil division (MCD) The primary governmental or administrative division of a county in many
states.
Noncontiguous Geographic areas that are not adjacent to one another and do not share a common
boundary.
Nonvisible boundary Boundaries, such as city, town, township, and property lines that do not follow a
physical feature.
Oklahoma tribal statistical area (OTSA) OTSAs are identified and delineated by the Census Bureau
in conjunction with federally recognized tribes and are intended to provide a geographic framework for
tabulating statistical data for federally recognized American Indian tribes that had an AIR in Oklahoma
prior to statehood.
OTSA tribal subdivisions Tribal subdivisions are units of self-government and/or administration within
an AIR and/or ORTL for a federally recognized tribe, or an OTSA, that serve social, cultural, and/or
legal purposes for the tribal government.
Regional Census Center (RCC) Temporary offices set up approximately two years prior to the
decennial census. The geographic staff from the permanent Regional Offices are assigned to the RCCs.
Relationship (geographic) A geographic area that shares a boundary with one or more other geographic
areas.

126

Shapefiles An ArcView GIS data set used to represent a set of geographic features such as streets,
hospital locations, trade areas, and ZIP Code boundaries. Shapefiles can represent point, line, or area
features. Each feature in a shapefile represents a single geographic feature and its attributes.
State liaison Person designated by the governor of each state with state recognized American Indian
tribes to work with the Census Bureau on the Tribal Statistical Areas Program.
State designated tribal statistical area (SDTSA) A tribal statistical area delineated for a state
recognized American Indian tribe that does not have an American Indian reservation. A SDTSA should
represent a compact, contiguous area containing a statistically significant concentration of people who
identify with a specific state recognized American Indian tribe in which there is structured or organized
tribal activity.
State American Indian reservation State American Indian Reservations (AIRs) and their legal
boundaries are established pursuant to state law. States may have an established process whereby staterecognized tribes can obtain a reservation. Several eastern states have continued to recognize state AIRs
established through laws, often treaties, of one of the original thirteen colonial assemblies and/or Great
Britain during the colonial era.
State Reservation Program (SRP) The SRP occurs once before each decennial census, and is a survey
of state American Indian reservations for those states with state-recognized tribes that are not also
federally recognized. Through the State Reservation Program, the Census Bureau accepts legal
boundary, name, official status updates as well as additions and updates to features such as roads or
rivers that serve as a boundary for the state AIR, as well as address range break information at the
boundaries.
Tribal block group A tribal statistical area that represents a collection of census blocks. Tribal block
groups nest within tribal census tracts and like tribal census tracts they are specifically delineated for
federall y recognized American Indian reservations (AIRs) and/or off-reservation trust lands (ORTLs)
without the imposition of state or county boundaries. Tribal block groups are otherwise conceptually
similar and equivalent to standard block groups.
Tribal census tract A tribal statistical area specifically delineated for federally recognized American
Indian reservations (AIRs) and/or off-reservation trust lands (ORTLs) without the imposition of state or
county boundaries. Tribal census tracts are otherwise conceptually similar and equivalent to standard
census tracts.
Tribal designated statistical areas (TDSA) A tribal statistical area delineated by a federally recognized
tribe that does not have an American Indian reservation and/or off-reservation trust lands. A TDSA
should represent a compact, contiguous area containing a statistically significant concentration of people
who identify with a specific federally recognized American Indian tribe in which there is structured or
organized tribal activity.
Tribal Statistical Areas Program (TSAP) The Tribal Statistical Areas Program (TSAP) is offered as a
part of the 2010 Decennial Census. It is a comprehensive but voluntary opportunity to update or

127

delineate, as appropriate, the diverse geographic statistical areas represented by American Indian and
Alaska Native areas (AIANAs).
Urbanized Areas (UAs) An urbanized area consists of densely settled territory that contains 50,000 or
more people. The Census Bureau delineates UAs to provide a better separation of urban and rural
territory, population, and housing in the vicinity of large places. UAs are redefined after each decennial
census. The UAs utilized in TSAP were defined just after 2000 using Census 2000 data.

OMB No. 0607-0795: Approval Expires 03/31/09

1. Introduction
The U.S. Census Bureau is the premier source of information about the American people
and the economy. The U.S. Constitution mandates that a census be taken every 10 years
in order to reapportion the House of Representatives. The data gathered by the decennial
census and other Census Bureau programs are used for several other purposes, including
the allocation and distribution of funds to state, local and tribal governments. Census
information shapes important policy decisions that in turn shape the nation’s social and
economic conditions. While best known for the decennial census, the Census Bureau
conducts numerous surveys and censuses that measure changing individual and
household demographics and the entire economic condition of the nation.
Census data help tribal elders and leaders understand what their communities need.
Many tribal communities use census information to attract new business and plan for
growth. In fact, many tribes and tribal organizations use census data to plan new
facilities and programs for the communities they serve.
In preparation for the 2010 Census, the U.S. Census Bureau has developed the Tribal
Statistical Area Program (TSAP) to collect updates to the inventory and boundaries of
American Indian and Alaska Native statistical geographic areas. Federally recognized
tribes with reservations or trust lands also have the opportunity to suggest features that
could be used as 2010 tabulation block boundaries as part of the Block Definition Project
(BDP). Participation in the TSAP is voluntary. If your tribe chooses not to participate,
the Census Bureau may revise the boundary of an existing area or delineate a new area in
accordance with published criteria and guidelines. The TSAP includes the following
statistical areas:
ƒ
ƒ
ƒ
ƒ
ƒ
ƒ

Alaska Native village statistical areas (ANVSAs)
Oklahoma tribal statistical areas (OTSAs) and tribal subdivisions on OTSAs
state designated tribal statistical areas (SDTSAs)
tribal designated statistical areas (TDSAs)
tribal census tracts (TCTs) and tribal block groups (TBGs) on American Indian
reservations (AIRs) and/or off-reservation trust lands (ORTLs)
census designated places (CDPs)

The Census Bureau will tabulate statistical data from the 2010 Census for each entity
type listed above, and will continue to use these areas to provide data from the American
Community Survey (ACS) through the coming decade. Meaningful statistical data from
the 2010 Census and ACS provide tribes and other data users with a tool to help them
make informed decisions and plan for community services. More information about the
background and components of these geographic areas as well as the delineation update
criteria and guidelines can be found in the Federal Register notice Vol. 73, No. 221 /
Friday, November 14, 2008, page 67470. This notice can also be accessed from our
TSAP webpage:
http://www.census.gov/geo/www/tsap2010/tsap2010.html

3

Each federally recognized tribe with a reservation or off-reservation trust land is eligible
to delineate CDPs and suggest boundaries to be held as 2010 Census block boundaries.
Your tribe may also be eligible to delineate multiple TCTs and/or TBGs. See Appendix
A for a list of all federally recognized tribes and the types of statistical American Indian
Areas (AIAs) they are eligible to delineate.
Tribes wishing to participate in the TSAP will have the option of delineating their
geographic statistical areas using paper maps or Census Bureau-provided shapefiles and
an ESRI® ArcGIS® extension specific to this program. Participants who chose to
submit changes using the digital method must have ArcGIS version 9.2 or 9.3. These
guidelines provide instructions for the use of paper maps. There are separate guidelines
for the use of the ESRI extension which are found on the data disc supplied by the
Census Bureau.
The TSAP Extension, developed by the Census Bureau for ESRI’s ArcMap 9.2, provides
a suite of GIS data management and editing tools/commands designed for participants to
identify, delineate, and review statistical areas. Project inception, quality control, data
submission, and workflow administration are all included in the data management
features of the extension. In addition to the inherent functionality of the ArcGIS
software, the extension’s unique editing tools consist of geographic area assignment,
block boundary definition, tribal tract/tribal block group type attribution, as well as line
editing and polygon split/merge functions. The option of using either the TSAP
extension or the paper maps to submit changes is at the complete discretion of each tribe
as neither is preferred over the other by the Census Bureau. However, depending on the
number anticipated updates and/or their complexity, you might consider using the TSAP
extension which offers you the ability to view population density within American Indian
statistical areas and allow you to more clearly add or remove area or adjust boundaries.
If you are interested in using this GIS application to submit your boundaries and you
have ArcGIS 9.2 or 9.3 software, but did not receive the ArcGIS extension software or
digital data files along with your materials, please contact the Census Bureau’s Regional
Census Center (RCC). 1 You may also contact the RCC staff to ask other questions or to
arrange for training.
These guidelines explain the criteria and complete instructions for delineating TCTs,
TBGs and CDPs and suggesting 2010 tabulation block boundaries using paper maps.

Disclosures to Respondents
The Geography Division manages programs to continuously update features, boundaries,
addresses, and geographic entities in the Master Address File / Topologically Integrated
Geographic Encoding and Referencing System (MAF/TIGER) database (MTdb) that is
used to support programs and to conduct the census and surveys. The TSAP program was
developed to give tribes the opportunity to review and update, if necessary, statistical
tribal entities for use in tabulating and publishing data from the 2010 Census, the
American Community Survey, and other surveys.
Public reporting burden for this collection of information is estimated to average 48 hours
per respondent, including time for reviewing instructions, assembling materials,
organizing and reviewing the information, and reporting any needed changes. We
anticipate that an estimated 650 participants will respond. Remaining entities may be
worked by Census Bureau regional staff. For larger areas or areas with many changes,
however, the respondent burden may be 180 hours or longer to complete. Please send
comments regarding this burden estimate or any other aspect of this collection of

2. Background
2.1.1 Background and Comparison of Tribal census tracts and block groups to standard
census tracts and block groups
Census tracts are the oldest and one of the most utilized statistical geographic entities for
which the Census Bureau tabulates data. The primary purpose of census tracts is to
provide a set of nationally consistent small, statistical geographic units, with stable
boundaries that facilitate analysis of data across time.

5

Tribal census tracts are statistical geographic entities defined by the Census Bureau in
cooperation with tribal officials, unique to and within the boundaries of federally
recognized American Indian reservations and/or off-reservation trust lands. Tribal census
tracts recognize the unique statistical data needs of federally recognized American Indian
tribes. The delineation allows for an unambiguous presentation of tract-level data
specific to the American Indian reservation and/or off-reservation trust lands without the
imposition of state or county boundaries.
For Census 2000 products in which data were presented by state and county, the standard
state/county census tract hierarchy was maintained, even for territory contained within an
AIR and/or ORTL. In such instances, the state/county portions of a tribal census tract
were identified as individual standard census tracts. These standard census tracts may not
have met the minimum population or housing unit thresholds, potentially limiting sample
data reliability or availability for both the tribal census tract and the derived standard
tracts. For the 2010 Census, the Census Bureau will identify tribal census tracts and
tribal block groups as a geographic framework completely separate from standard census
tracts and standard block groups (Figure 1). The change for tribal census tracts and tribal
block groups for the 2010 Census seeks to eliminate, in part, the data issues associated
with the Census 2000 approach, so that for the 2010 Census more census tracts and block
groups, both tribal and standard, will meet the population and housing unit thresholds.
The proposed separation of these two geographic frameworks will apply to data
tabulation products, as well as to geographic information products.

Figure 1: In Census 2000, standard and tribal tracts were both used to present data in the
standard data hierarchy. In this example, the tribal tract above would have been split by a
6

county boundary, creating tracts that did not meet the criteria potentially limiting sample
data reliability or availability. For Census 2010, tribal tract and block group boundaries
will be completely independent from standard tracts and block groups.
The primary operational benefit of this change for the tribes is that they do not have to
work with any other governments or data users in delineating their tribal census tracts and
tribal block groups. Delineating tribal census tract and tribal block groups allow tribes to
derive more meaningful data for specific geographic areas within their AIRs and/or
ORTLs. Standard census tracts and standard block groups are delineated by a primary
participant in the Participant Statistical Areas Program (PSAP) (usually a regional
planning organization or county government agency), with input from a large variety of
data users who may represent competing interests. Tribes are encouraged to work with
the other PSAP participants for any areas in which they are interested 2 , on and off their
AIRs and/or ORTLs, to help define standard census tracts and standard block groups.
For federally recognized American Indian tribes with AIRs and/or ORTLs that have more
than 2,400 residents or 960 housing units (using Census 2000 data or more current tribal
data), the Census Bureau will offer the tribal government the opportunity to delineate
multiple tribal census tracts and tribal block groups on their AIR and/or ORTL. For
federally recognized tribes with an AIR and/or ORTLs that have fewer than 2,400
residents or 960 housing units, the Census Bureau will define one tribal census tract
coextensive with the AIR and/or ORTL. Federally recognized tribes with AIRs and/or
ORTLs that have at least 1,200 residents or 480 housing units may define multiple tribal
block groups on their AIR and/or ORTL. For federally recognized tribes with an AIR
and/or ORTLs that have fewer than 1,200 residents or 480 housing units, the Census
Bureau will define one tribal block group coextensive with the AIR and/or ORTL.
Tables 1 and 2 provide population and housing unit thresholds for both standard and
tribal census tracts and block groups.

All tribal census tracts and tribal block groups must follow all of the published criteria
and guidelines for standard block groups and standard census tracts (see section 3 for
criteria and guidelines), except that they do not have to nest within states or counties.
2

Contact your RCC if your tribe is interested in participating in PSAP (See Appendix C).

They must nest within an individual AIR and/or ORTL and must be identified uniquely
so as to clearly distinguish them from standard census tracts and block groups.
While there will be a separate hierarchy for standard and tribal census tracts and block
groups in 2010, there will only be one set of 2010 tabulation blocks. Tabulation blocks
are the smallest geographic unit for which the Census Bureau tabulates decennial census
data. Tabulation blocks will be numbered with a 4-digit code, the first digit being the
number of the standard block group in which it nests. For example, tabulation block
1001 is in standard block group 1 and block 2001 is in standard block group 2. Because
census blocks will be numbered within standard block groups and tribal block groups will
be identified uniquely from standard block groups, there will not be a relationship
between tribal block group identifiers and census block numbers. Thus, tribal block
group A might contain census blocks numbered in different ‘‘thousand’’ ranges (e.g.,
blocks 1001, 2001, and 3001).
2.1.2 The Importance of Population and Housing Unit Thresholds
Tribal census tracts and tribal block groups defined for the 2010 Census will be used to
tabulate data from the ACS. As a general rule, estimates from programs providing
sample data, including the ACS, for geographic areas with smaller populations will be
subject to higher sampling variances than comparable estimates for areas with larger
populations. In addition, the availability and amount of data published for geographic
areas with small populations may be reduced compared to that for geographic areas with
larger populations. Aiming to create tribal census tracts that meet the optimal population
of 4,000 or the optimal housing unit threshold of 1,600, and at least maintaining the
minimum population threshold of 1,200 or 480 housing units, will improve the reliability
and availability of data, and PSAP and TSAP participants should consider these factors
when defining both tribal and standard tracts. A similar relationship between size of
population and reliability and availability of data applies to tribal block groups and
standard block groups.
All statistical geographic entities, are reviewed by the Census Bureau, compared against
published criteria and guidelines, and accepted on a case-by-case basis. The Census
Bureau uses Census 2000 population and housing unit counts to verify that a tribal census
tract or tribal block group meets the thresholds, and if the thresholds are not met, the
Census Bureau may ask for other supporting information, such as tribal or local estimates
for the same area. Housing unit counts will be emphasized over population counts for
seasonal and other unique communities that may have no or low population on Census
Day (April 1). The housing unit thresholds are based on a national average of 2.5 persons
per housing unit. The Census Bureau recognizes that there are regional variations to this
average, and will take this into consideration when reviewing all tribal census tract and
tribal block group proposals, if notified. On a case-by-case basis, the Census Bureau may
waive the maximum population and housing thresholds, if requested, and if supplied an
appropriate explanation. Both population and housing unit data can be found by
accessing American FactFinder on the Census Bureau’s internet website. Directions for
obtaining this data can be found in Appendix B.

2.1.3 Census Designated Places
CDPs are statistical geographic areas representing closely settled, unincorporated
communities, which are locally recognized and identified by name. They are the
statistical equivalents of incorporated places, with the primary differences being the lack
of both a legally defined boundary and an active, functioning governmental structure,
chartered by the state and administered by elected officials. The primary goal of CDPs is
to map a boundary for and provide statistics for well-known, unincorporated localities. A
CDP generally consists of a contiguous cluster of census blocks comprising a single piece
of territory and containing a mix of residential and commercial uses similar to that of an
incorporated place of similar size. Some CDPs, however, may be predominantly
residential; such places should represent recognizably distinct, locally known
communities, but not typical suburban subdivisions.
CDPs are delineated through both the TSAP and the PSAP for the 2010 Census.
Federally recognized tribes with AIRs, ORTLs, or OTSAs may update or delineate new
CDPs within the boundary of their reservation, trust lands, or OTSA through the TSAP.
Tribes that would like to delineate CDPs for communities completely off their legal or
statistical area should work through the PSAP with the primary participants for the areas
in which they are interested. Contact your RCC for more information on PSAP.
2.1.4 Block Definition Project (BDP)
The BDP provides an opportunity for tribes to flag existing features that tribes want the
Census Bureau to use as 2010 tabulation block boundaries. In some cases, there may be a
physical or visible feature that is significant to the landscape and serves as a determining
factor in how population has settled on the reservation. If this is the case and the Census
Bureau does not show this feature on our map, the tribe may want to add the feature and
identify it as a suggested 2010 block boundary. Examples of this type of feature are:
above ground pipelines, ridgelines, irrigation systems, fence lines, or the edge of a
canyon. These types of features are not standard for inclusion on Census files and
products because we have no standard method for updating or collecting them. They do
however, make excellent boundaries for statistical areas such as tribal tracts, CDPs or
census blocks. For this reason they are acceptable for inclusion in the Block Definition
Project. Upon receipt of a block boundary suggestion the Census Bureau will determine
its eligibility for inclusion as a 2010 tabulation block boundary.
Below is a list of all the feature and boundary types that are currently already planned to
be held as 2010 Census tabulation block boundaries and therefore do not need to be noted
as suggested holds on the paper maps. In some instances you may not want a feature to
become a 2010 Census tabulation block boundary such as where there are roads
identified in our files as double lined roads. Due to recent updates to our data, there are
now many more roads identified as double line roads that, in the past, were classified as
single line roads. This causes the area in the middle (a median strip for example) to
become a long narrow block. If you do not want the polygon formed by the two road
edges to be a separate 2010 Census tabulation block, you may want to consistently flag
one of the edges with a “Do Not Hold.”
9

Note: If any other program sponsored by the Census Bureau uses that line as a boundary,
the Census Bureau will override the “Do Not Hold” status of the line.
Entities: The boundaries, as of January 1, 2010, for each of the entities listed below, are
planned 2010 Census tabulation block boundaries and therefore do not have to be flagged
as a 2010 block boundary.

2.2 Tribes eligible to delineate TCTs, TBGs, CDPs and participate in the BDP
Federally recognized tribes are eligible to delineate TCTs, TBGs, CDPs, or participate in
the BDP if they have a reservation or off-reservation trust lands. Federal recognition of
an American Indian tribe specifically means that the tribe is recognized by and eligible to
receive services from the Bureau of Indian Affairs (BIA). BIA recognition is determined
by inclusion of a tribe on the BIA’s list of recognized tribes or by addenda to the list as
published by the BIA.
All AIR and ORTLs will have at least one TCT and one TBG. If the AIR and/or ORTL
have enough population or housing units to meet the minimum population and/or housing
unit count thresholds (1,200 and 480 respectively) for the tribe is eligible to delineate
multiple TCTs and TBGs. Likewise, if the AIR and/or ORTL have enough population or
housing units to meet the minimum population or housing unit count thresholds (600 and
240 respectively), the tribe is eligible to delineate multiple TBGs. (If you are interested
in obtaining Census 2000 population and housing unit counts for TCTs, TBGs, blocks or
other areas, you can find that information on the Census Bureau’s website. See Appendix
B for instructions on obtaining that information through the American FactFinder). All
federally recognized tribes with AIRs/ORTLs, regardless of population or housing unit
counts are eligible to delieate CDPs and participate in the BDP.
Participation in TSAP is voluntary. If your tribe chooses not to participate, the Census
Bureau will delineate TCTs and TBGs for your AIR/ORTL in accordance with published
criteria and guidelines. The Census Bureau will not delineate any CDPs. For a complete
list of all federally recognized tribes and the statistical areas they are eligible to delineate
through TSAP, see Appendix B.
2.3 The Boundary and Annexation Survey
The Boundary and Annexation Survey (BAS) is an annual Census Bureau survey of legal
geographic entities that includes federal AIRs, ORTLs, and any associated tribal
subdivisions. Whereas the TSAP provides the process for reviewing and updating those
AIAs that are statistical geographic entities (TCTs, TBGs, and CDPs), the BAS provides
the process for reviewing and updating AIAs that are legal federal geographic entities,
such as the reservation itself, tribal subdivisions and ORTLs. Its purpose is to determine,
solely for data collection and tabulation by the Census Bureau, the complete and current
inventory and the correct names, legal descriptions, official status, and official, legal
boundaries of the legal geographic entities with governmental authority over certain areas
within the United States, as of January 1 of the survey year. The BAS also collects
specific information to document the legal actions that established a boundary or imposed
a boundary change. In support of the government-to-government relationship with
federally recognized American Indian tribes, the Census Bureau works directly with
tribal officials on the BAS. Through the BAS, the Census Bureau also accepts updates to
features such as roads or rivers, and address range break information at the boundaries. If

11

you wish to update boundaries for you reservation, off-reservation trust lands or legal
tribal subdivisions, you should do so through the BAS.
For more information about the BAS, contact your RCC or see the Census Bureau's Web
site at http://www.census.gov/geo/www/bas/bashome.html. The BAS Respondent
Guide for federally recognized tribes is available at:
http://www.census.gov/geo/www/bas/bas09/bas09_mat_aia.html
2.4 Schedule
In October 2008, the Census Bureau mailed formal letters to tribal officials inviting them
to participate in TSAP. These guidelines accompany the paper maps required to
complete the work. Tribes have 120 days from the date they receive these materials to
review and submit their geographic statistical area delineations or updates to the Census
Bureau’s RCC. In late 2009, after the Census Bureau has reviewed and incorporated
your delineations into our geographic database, you will receive new maps or digital files
so that you can verify that the Census Bureau has inserted your boundaries correctly. If
you have questions regarding your delineation or submission, assistance will be available
from geographers at the Census Bureau’s RCC.
2.5 Materials needed for delineating TCTs, TBGs, CDPs and suggesting 2010
tabulation census block boundaries
The types of paper maps you receive will vary depending on the size and mapping
complexity of each federal AIR/ORTLs. Federal AIR/ORTLs that are smaller in land
area may only receive a single mapsheet while federal AIR/ORTLs with large land areas
may receive an index map, a series of parent maps, and a number of inset maps. An
index map shows the complete federal AIR/ORTL with gridlines defining specific areas
shown on each parent map. A parent map shows a detailed version of a single grid box
from the index map, and an inset map shows finer details of areas within the parent map
where the feature network is too dense to represent clearly at the map scale of the parent
map. You can think of the inset map as a “blow-up” of a specific area.

Figure 2: Example of Index, Parent and Inset maps

12

The RCC will provide federally recognized tribes with AIRs and/or ORTLs with an index
map depicting the federal AIR/ORTL boundary(s) and all associated parent and inset
maps. The maps will show the tribal census tracts and tribal block group boundaries that
were delineated prior to Census 2000 within the most current AIR/ORTL boundary.
These boundaries should closely match the Census 2000 tribal census tracts and block
groups, except on those AIR/ORTLs that have had significant boundary changes since
2000. Figures 3 and 4 show the boundaries on your maps and how they are symbolized.

Figure 3: Example of Census map symbology for TCTs, TBGs, and census blocks.

Figure 4: TSAP map symbology
13

The Census Bureau requests that participants use a pencil with orange lead to annotate
tribal census tract boundaries, a pencil with brown lead to annotate block group
boundaries, and a pencil with red lead to annotate census designated places on the paper
maps provided. Procedures for annotating the paper maps are detailed in section 4.
2.6 Important information on features
2.6.1 Acceptable features for use as statistical area boundaries
Statistical area boundaries may follow specified legal or administrative boundaries that
do not change greatly over time. A list of legal or administrative boundaries is provided
below:
ƒ
ƒ
ƒ
ƒ
ƒ

American Indian reservation
Off-reservation trust land
Tribal subdivision
State
County
County subdivision
Incorporated place

Statistical area boundaries may also follow permanent, visible features, such as roads,
perennial streams, railroads, and high-tension power lines. Permanent visible features
should be easily locatable in the field by Census Bureau staff without ambiguity. The
acceptable visible boundary features are:
ƒ

powerline (above ground, high-tension)
aerial tramway/ski lift
natural topographic features
cliff/escarpment
perennial shoreline
railroad features (main)
carline, streetcar track, monorail, other mass transit rail
interstate highway or primary road with limited access
primary road without limited access, US highway, state highway or county
highway, secondary and connecting roads
local neighborhood road, rural road, city street
service drive (usually along a limited access highway)
alley
14

ƒ

fencelines

Natural topographic features include the crests of well-defined mountain ridges; the rims
or bases of sharply defined escarpments, cliffs, or bluffs; the position of dry ravines or
arroyos; as well as other features as long as the features are not also mimicked by another
visible feature, have no housing in the vicinity, and are easily located on the ground.
2.6.3 Boundary feature updates
Data user and Census Bureau experience has shown that some features make better
boundaries than others, and the same type of feature can make an excellent boundary in
one place and a poor one in another. Rivers, major canals, lakes, and other bodies of
water often make good statistical area boundaries because they generally limit access
from one area to another and rarely change relative location. Other features that limit
access between areas, such as interstate and other major highways, railroad tracks, and
the ridges of mountain ranges, also make good statistical area boundaries. In some
instances, however, such a feature unifies a community, for example, a lake forming the
core of a recreational housing development or a through street forming the spine of a
subdivision. In these circumstances, the statistical area boundary should include the
entire area of the lake or both sides of a unifying street to better encompass similar
community patterns.
In general, when delineating boundaries in bodies of water represented as polygons and
having area (lakes, reservoirs, bays, oceans, and wide rivers), the boundary should follow
a line bisecting the water body rather than following a shoreline. Wherever possible, use
an existing line in water (for example, a county line in the middle of a river) rather than
adding a new line.
Officials delineating statistical AIAs may only add nonvisible lines as a boundary if other
acceptable boundary features such as roads, rivers, streams, shorelines, trails and
ridgelines, are not available and they aid in a statistical AIA meeting other specific,
delineation criteria and/or guidelines. The Census Bureau staff will contact you if they
require more information or have questions about feature updates submitted as part of our
2010 TSAP.
2.7 Current state of Census road features
The Census Bureau has spent the last six years enhancing the spatial accuracy of the
roads in our geographic database system. The local files used during this project were
required to have an overall average accuracy of 7.6 meters while some files were more
accurate.
Although much of the street network is vastly improved, as you work with our maps you
may notice that in some counties the street and boundary features look distorted. A line
that should be straight may have a noticeable kink or pointed shape. The Census Bureau
is working to correct these problems, therefore if you need to use a feature that is
distorted follow the guidelines below.

15

The Census Bureau is now moving forward with our 2010 Census field canvassing and
collection activities. This means that we are no longer processing realignments to our
street network. What is critical for the success of the 2010 Census data tabulation is the
location of roads relative to the tabulation entity boundary. As long as the road is within
the correct entity, the population and housing will be properly reported. The guidelines
below also explain what updates are acceptable as part of the TSAP.
It is critical that participants understand that TSAP is not intended for street feature
updates except where a boundary follows a road (or other visible feature such as a
stream) and the road is not reflected in our file. For this reason the Census Bureau can
not accept street (or other) feature updates that do not follow the guidelines below:
2.7.1 Guidelines for Updating Features
1. If a feature is missing and it forms the boundary for the area you are defining, add the
feature and provide the name.
2. If you can not correctly delineate the boundary for an entity you are updating because
the feature you need to follow is incorrectly located, mislabeled or distorted in the
Census Bureau’s map, we request that you fix that feature only. In addition, we
request that you report the problem area to the Census Bureau (through your RCC) by
sending information describing the incorrect feature and the specific entity boundary
affected.
3. Do not add streets that are missing for an entire housing development (add only
streets that are needed to form a boundary). We will be adding new or missing streets
during our address canvassing operation which will occur in the spring and early
summer of 2009. The Census Bureau will provide verification materials for each
participant that returns their submission in the correct format and within the allotted
120 days. These materials will show the results of address canvassing. If these
streets are still missing at that time, we will accept these streets as adds.
2.8 Feature Extension Criteria
If you want to use an existing feature that doesn’t form a closed polygon, you may add a
short line to connect the features and close the polygon. The Census Bureau refers to
these lines as feature extensions and several requirements pertain. To avoid creating
ambiguous Census block boundaries, we require that feature extensions:
ƒ Are no longer than 300 feet;
ƒ Are straight lines from the end of a road and intersecting a non-road feature
(These include all hydrographic features, pipelines, powerlines, and railroads.);
ƒ Do not intersect a cul-de-sac.

16

3. Criteria
The following criteria and guidelines were developed to help ensure that the statistical
areas delineated for the 2010 Census and beyond support their intended purpose, to
provide useful and meaningful data for the respective tribe, and enhance the ability of
data users to make comparisons between data for the various types of AIAs. Criteria are
rules that must be followed by all officials delineating statistical AIAs for the 2010
Census, while guidelines are the Census Bureau’s suggested approach for improving the
relevance and utility of statistical AIAs.
3.1 Tribal census tract Criteria and Guidelines
The tribal census tract criteria are:
1. TCTs may not cross AIR/ORTL boundaries.
2. The entire land and water area of an AIR/ORTL must be covered by one or more
TCTs.
3. TCTs should be labeled by writing “T” followed by three digits, beginning with
“T001, T002, etc.” Be sure that each new TCT label number is only used once
within the AIR/ORTL.
Guidelines for delineating tribal census tracts are:
1. Census tracts should have 4,000 people or 1,600 housing units. Meeting or
exceeding the optimum thresholds will help improve the reliability of sample data
for TCTs.
2. Each TCT must encompass at least 1,200 people or at least 480 housing units
unless it is flagged as a special land use tract (see section 3.5).
3. A TCT must comprise a reasonably compact and contiguous land area.
4. TCT boundaries should follow visible and identifiable features.
3.2 Tribal block group criteria and guidelines:
The tribal block group criteria are:
1. TBGs must not cross TCT boundaries.
2. Because TCTs must cover the entire area of each AIR/ORTL, by definition, TBGs
also must cover the entire area of each AIR/ORTL.
3. TBGs will be designated with a single capital letter from “A” through “K” (except for
the letter “I”). Tribal block group identifiers must be unique within TCTs.
Guidelines for delineating tribal block groups are:
1. Each block group must encompass at least 600 people or at least 240 housing units
unless it is coextensive with a flagged special land use tract (see section 3.5).
2. A block group must comprise a reasonable compact, contiguous land area.
3. Noncontiguous block groups are permitted only where a contiguous area or
inaccessible area would not meet population or housing unit count requirements for a
separate TBG, in which case the non contiguous or inaccessible area must be
combined with a proximate block group.

17

Figure 5: This is an example of an acceptable noncontiguous TBGs and TCTs.
4. Block group boundaries should follow visible and identifiable features.
In the handful of cases where there are Joint Use Areas, the Census Bureau will
automatically delineate one tribal census tract containing one tribal block group in each
of those areas. Tribes are not responsible for making these delineations on their maps.
3.3 Special Land Use TCTs and TBGs
To recognize and distinguish the special uses of some parcels of land, the Census Bureau
allows for the definition of special land use tribal census tracts or block groups. Specific
areas such as ceremonial grounds, historic sites, and parks can be identified as special
land use TCTs or TBGs. These areas must have an official name, generally have little or
no residential population or housing unit (or meet the non special land use TCT or TBG
population and housing unit thresholds) and must be contiguous. If located in a densely
populated urban area, a special land use TCT or TBG must have an area measurement of
approximately 1 square mile or more. If delineated completely outside an urban area, a
special land use TCT or TBG must have an area of approximately 10 square miles or
more. Participants are not required to delineate special land use TCTs or TBGs.
18

The Census Bureau recognizes that some special land use areas not intended for
residential population, such as parks, may contain some population, such as caretakers or
the homeless. Our intent is to allow for the delineation of parks and other special land
use areas as separate TCTs and therefore we will accept such areas as special land use
TCTs even if some, but very little, residential population is present.
3.4 Census designated place criteria and guidelines:
The census designated place criteria are:
1. CDPs cannot be coextensive with an entire AIR, ORTL, OTSA, or any other AIA, but
may extend off AIRs, ORTLs, or OTSAs.
2. A CDP may not have the same name as an adjacent or nearby incorporated place. If
the community does not have a name that distinguishes it from other nearby
communities, then the community is not a distinct place and should not be submitted
as a CDP.
3. A CDP may not be located, either partially or entirely, within an incorporated place or
another CDP.
4. A CDP must not cross state boundaries, but may be located in more than one county.
Guidelines for delineating census designated places are:
1. A CDP constitutes a single, closely settled center of population that is named. To the
extent possible, individual unincorporated communities should be identified as
separate CDPs.
2. A CDP is defined to provide data for a single named locality, therefore the Census
Bureau does not encourage delineating CDPs that comprise a combination of places
or are identified by hyphenated names. For example, CDPs such as Poplar-Cotton
Center and Downieville-Lawson-Dumont are no longer acceptable. Prior to Census
2000 communities were sometimes combined as a single CDP in order to comply
with the Census Bureau minimum population requirements. The Census Bureau’s
elimination of population threshold criteria has made such combinations unnecessary.
3. Multiple communities may only be combined to form a single CDP when the
identities of these communities have become so intertwined that the communities are
commonly perceived and referenced as a single place.
4. Multiple communities also may be defined as a single CDP when there is no
distinguishable or suitable feature in the landscape that can be used as a boundary
between the communities, even if the two communities still have separate identities.
5. There is no minimum population or housing unit thresholds for defining CDPs
however, a CDP must contain some population or housing units or both. Participants
submitting boundaries for places with less than ten housing units may be asked to
provide additional information attesting to the existence of the CDP.
6. CDP boundaries should follow the visible features outlined in section 2.6. CDP
boundaries may follow other nonvisible features in instances where reliance upon
visible features will result in over bounding of the CDP and the intent is to include
housing units on both sides of a road or street feature. Such non visible boundaries

19

might include parcel boundaries and public land survey system lines; national, state,
or local park boundaries.
7. The CDP name should be one that is recognized and used in daily communication by
the residents of the community.
8. A CDP should have population during at least one entire season of the year, and have
a higher housing unit and population density than surrounding areas.

4. Procedures
4.1 Annotation of Maps
The Census Bureau suggests the following procedures for delineating TCTs, TBGs,
CDPs and for suggesting Census 2010 Block Boundaries:
1. Compare your source materials with the Census Bureau’s maps. The goal of the
TSAP is to delineate statistical areas that adhere to the criteria and guidelines outlined
in section 3. Following these guidelines will provide your tribe with census and
survey statistics throughout the next decade.
2. If after reviewing our maps you believe that the boundary of your tribes federal
reservation or trust land is inaccurate as portrayed on the Census Bureau’s maps,
please refer to section 2.3 The Boundary and Annexation Survey for more
information or contact your RCC.
3. If you are satisfied with how the TCTs, TBGs, and/or CDPs are portrayed on the map,
and you do not wish to identify any features for use as 2010 census block boundaries,
fill out and sign the form attached to the cover letter that came with your materials.
Return the form to the RCC using the postage paid envelope provided.
4. If you need to update or delineate new TCTs, TBGs, and/or CDPs, annotate the maps
with the revised or new boundary, name and number (T001, T002, etc.) updates and
revisions. Use the following sequence when annotating the boundaries of Census
2010 statistical areas, according to the criteria provided in section 3.
Do not add street or other features unless you are adding a feature that forms the
boundary of a TCT, TBG and/or CDP or is a suggested block boundary. The Census
Bureau will not accept new road features at this time unless the road or other feature is
used to delineate a boundary or to suggest a block boundary. When adding a feature for
these purposes, use a black lead pencil to add and label the feature then use the
appropriate colored pencil as described below to annotate the feature as a boundary. If a
feature is incorrectly located, mislabeled or distorted on the Census Bureau’s maps to the
extent that you cannot correctly delineate a boundary using that feature, please draw your
boundary following the problematic feature and using the appropriate colored pencil.
Also, be sure to contact your RCC to describe the location and nature of the problem.
a. Annotate the TCT boundaries and numbers T001, T002, etc. in orange
pencil. It is not necessary to annotate a TCT if you only have one TCT
that will be coextensive with the AIR and/or ORTL. The Census Bureau
will automatically identify 1 TCT for each reservation with a population
of less than 1,200.

20

b. Next annotate the TBG boundaries and labels (A, B, C, etc.) in brown
pencil. (Because TBGs nest within TCTs, there is no need to annotate
brown lines alongside or on top of census tract boundaries.) There is no
need to annotate a TBG, if you only have one TBG coextensive with the
AIR and/or ORTL. The Census Bureau will automatically identify 1 TBG
for each TCT with a population of less than 600.
c. Then annotate the maps with the CDP updates in red pencil. CDPs do not
inherently follow any other statistical boundary. However, where a CDP
boundary follows an annotated color boundary for either a revised TCT
(orange), or TBG (brown), annotate red circles along the portions of the
colored lines where the revised CDPs boundaries are coincident with any
other revised statistical areas. (It is not required to delineate CDPs.)
5. If the CDP name requires revision, cross out the old name and clearly label the new
name in red within the boundary of the federal AIR.
6. On the paper map, revise an existing boundary by drawing “X”s along the boundary
using the appropriate colored pencil (orange for TCT boundary, brown for TBG
boundary, red for CDP boundary).
7. If you want to suggest a feature as a 2010 tabulation block boundary, highlight the
feature in purple. If you wish to indicate a feature should not be held as a 2010
tabulation block boundary, draw triangles on the feature using a purple pencil.
4.1.1 Example

21

Figure 6: In this example, the tribal block group boundary has been changed. The old
boundary has been crossed out and the new boundary has been marked using a brown
pencil. A CDP has been created and where the two statistical areas now share a
boundary, the CDP is delineated using red circles. Also, a road in the lower left hand
corner has marked with purple pencil, showing that it is to be held as a 2010 tabulation
block boundary.
4.2 Transmitting Completed Submissions and Census Bureau Review
Please return all maps to the RCC in the same tube/box/envelope you received it in and
for your convenience use the mailing label provided. The Census Bureau RCC
geographic staff will review that the submitted TCTs, TBGs, CDPs and block boundary
suggestions to make sure they are complete and meet all criteria and other requirements.
Where the criteria have not been met, they will review the submitted justification or call
to acquire justification.
The Census Bureau’s RCC staff will provide feedback to the participant on their
submission, and if necessary provide additional guidance on the criteria and guidelines
usage. They may also need to contact you with any questions or concerns regarding the
submission. The Census Bureau reserves the right to modify, create, or reject any
boundary or attribute as needed to meet the final program criteria and guidelines, or to
maintain geographic relationships before the tabulation geography is finalized for the
2010 Census.
4.3 Verification
As long as a submission for TSAP is received by the Census Bureau within the 120 day
schedule, each participating tribe will be eligible for a verification phase. During
verification, the Census Bureau provides new materials to reflect how we inserted the
submitted TCT, TBG, and CDPs into our database. The verification materials will be
provided in late 2009. At that time, tribes may review the new areas and as needed make
minor boundary corrections.

Appendix B – Procedures for accessing population and housing unit
data from American FactFinder
1. Starting at the U.S. Census Bureau internet homepage, click on “American FactFinder”
within the list along the left side of the screen.

39

2. On the next page, you will see another list on the left side on the screen. Hover your
mouse over “Data Sets” and then click on “Decennial Census” in the menu that pops up.

40

3. On the next screen, you will have the option of choosing between several different data
sets along with a small description of what each one contains. In this example, we will
access tribal block group data. For block group population data, you should select the
first data set listed which is “Census 2000 Summary File 1.” You may want to scroll
through the other data sets to see what other information is available for your future
reference.

41

4. To extract data, you will now select a number of parameters to identify your area of
interest. Again, in this example we will access tribal block group data, but you can also
access data for reservations, off-reservation trust lands, tracts, blocks, and many other
geographic areas.

42

5. Finally, you will select the specific type of data within “Census 2000 Summary File 1”
that you are looking for. Remember that you may select multiple data types.

6. After clicking “Show Result” you will now see the data you have requested.

OMB No. 0607-0795: Approval Expires 03/31/09

1. Introduction
The U.S. Census Bureau is the premier source of information about the American people
and the economy. The U.S. Constitution mandates that a census be taken every 10 years
in order to reapportion the House of Representatives. The data gathered by the decennial
census and other Census Bureau programs are used for several other purposes, including
the allocation and distribution of funds to state, local and tribal governments. Census
information shapes important policy decisions that in turn shape the nation’s social and
economic conditions. While best known for the decennial census, the Census Bureau
conducts numerous surveys and censuses that measure changing individual and
household demographics and the entire economic condition of the nation.
Census data help tribal elders and leaders understand what their communities need.
Many tribal communities use census information to attract new business and plan for
growth. In fact, many tribes and tribal organizations use census data to plan new
facilities and programs for the communities they serve.
In preparation for the 2010 Census, the U.S. Census Bureau has created the Tribal
Statistical Areas Program (TSAP) to collect updates to the inventory and boundaries of
American Indian and Alaska Native statistical geographic areas. Participation in the
TSAP is voluntary however, if your tribe chooses not to participate, the Census Bureau
may update the boundary of an existing area or delineate a new area in accordance with
published criteria and guidelines. The TSAP includes the following statistical areas:
ƒ
ƒ
ƒ
ƒ
ƒ
ƒ

Alaska Native village statistical areas (ANVSAs)
Oklahoma tribal statistical areas (OTSAs) and tribal subdivisions on OTSAs
state designated tribal statistical areas (SDTSAs)
tribal designated statistical areas (TDSAs)
tribal census tracts (TCTs) and tribal block groups (TBGs) on American Indian
reservations (AIRs)/ off-reservation trust lands (ORTLs)
census designated places (CDPs)

The Census Bureau will tabulate statistical data from the 2010 Census for each entity
type listed above, and will continue to use these areas to provide data from the American
Community Survey (ACS) through the coming decade. Meaningful statistical data from
the 2010 Census and the ACS provide tribes and other data users with a tool to help them
make informed decisions and plan for community services. More information about the
background and components of these geographic areas can be found in the Federal
Register notice Vol. 73, No. 221 / Friday, November 14, 2008, page 67470 which can be
accessed from the TSAP website at
http://www.census.gov/geo/www/tsap2010/tsap2010.html.
These guidelines explain the criteria and complete instructions for delineating TDSAs
using paper maps. The subjects covered are:

Census Bureau Submission Review
Verification

Those wishing to delineate TDSAs will have the option of using their paper maps or
Census Bureau-provided Geographic Information System (GIS) data, tools, shapefiles,
and ESRI® extension specific to this program. Participants who choose to submit
changes using the digital method must have ArcGIS® 9.2.
The TSAP Extension, developed by the Census Bureau for ESRI’s ArcMap 9.2, provides
a suite of GIS data management and editing tools/commands designed for participants to
identify, delineate, and review statistical areas. Project inception, quality control, data
submission, and workflow administration are all included in the data management
features of the extension. In addition to the inherent functionality of the ArcGIS
software, the extension’s unique editing tools consist of geographic area assignment, as
well as line editing and polygon split/merge functions. The option of using either the
TSAP extension or the paper maps to submit changes is at the complete discretion of
each tribe as neither is preferred over the other by the Census Bureau. However,
depending on the number anticipated updates and/or their complexity, you might consider
using the TSAP extension which offers you the ability to view population density within
American Indian statistical areas and allow you to more clearly add or remove area or
adjust boundaries. If you are interested in using a GIS application to submit your
boundaries and you have ArcGIS 9.2 or 9.3 software, but did not receive the ArcGIS
extension software or digital data files along with your materials, please contact your
Regional Census Center. You may also contact RCC staff to ask other questions or
arrange for training 1 .
Disclosures to Respondents
The Geography Division manages programs to continuously update features, boundaries,
addresses, and geographic entities in the Master Address File / Topologically Integrated
Geographic Encoding and Referencing System (MAF/TIGER) database (MTdb) that is
used to support programs and to conduct the census and surveys. The TSAP program was
developed to give tribes the opportunity to review and update, if necessary, statistical
tribal entities for use in tabulating and publishing data from the 2010 Census, the
American Community Survey, and other surveys.
Public reporting burden for this collection of information is estimated to average 48 hours
per respondent, including time for reviewing instructions, assembling materials,
organizing and reviewing the information, and reporting any needed changes. We
anticipate that an estimated 650 participants will respond. Remaining entities may be

worked by Census Bureau regional staff. For larger areas or areas with many changes,
however, the respondent burden may be 180 hours or longer to complete. Please send
comments regarding this burden estimate or any other aspect of this collection of
information, including suggestions for reducing this burden to:

You may e-mail comments to [email protected]. Use “Paperwork Project 06070795” as the subject.
Responses to this survey are voluntary. The authority for conducting these activities is
covered under the legal authority of Title 13 U.S.C. Sections 141 and 193.
No agency may conduct and no person may be required to respond to a collection of
information unless it displays a valid Office of Management and Budget (OMB) approval
number. The OMB approval number for this information collection is 0607-0795.

2. Background on TDSAs and the TSAP
2.1 Purpose of TDSAs
In an effort to improve the presentation of data for federally recognized American Indians
that did not have a reservation or off-reservation trust lands, boundaries for TDSAs were
first introduced for the 1990 Census of Population and Housing, and then revised during
Census 2000. Prior to 1990, data were only tabulated for federal and state recognized
reservations and off-reservation trust lands, legal tribal subdivisions and the Historic
Areas of Oklahoma (now called OTSAs). As part of the 2010 Census, TSAP eligible
tribal officials will again have the opportunity to review and update the boundaries of
their existing TDSA or delineate new TDSA.
The primary purpose for delineating a TDSA is to obtain meaningful statistical data for a
recognized tribe within a geographic area encompassing a substantial concentration of
tribal members. TDSAs are intended to identify lands associated with federally
recognized tribes that do not have an American Indian reservation or off-reservation trust
lands and provide them with meaningful statistical data that is relevant to their current
data needs and present day location. A TDSA is intended to be comparable to the AIRs
within the same state or region, especially those for tribes that are of similar size, for
analyzing data over time and to provide a way to obtain comparable data. The
boundaries of a TDSA may not necessarily include all tribal members if, for example, a
tribe has tribal members living in many areas of the county or state. TDSAs do not depict
land ownership or represent an area over which a tribe has any form of governmental
authority or jurisdiction, nor do they represent all of the traditional or historical areas
associated with the tribe, including areas used for subsistence activities. A TDSA should
5

represent a geographic area where there is a concentration of tribal population currently
living and where the tribe has social, economic or historical ties to the land. These
should be evidenced by the existence of tribally owned businesses, buildings, meeting
areas or culturally significant structures.
Statistical data will be tabulated for all people living within the boundaries of a TDSA
(including non-tribal members), and also for all tribal members regardless of where they
reside in the state or nation. Each individual, whether or not he or she is located on a
tribal area, will have the same opportunity to identify their tribal affiliation. While data
tabulated for a well defined TDSA will provide a rich source of statistical and
demographic information for your statistical area, it is not necessary for an individual to
be living within the boundary of the TDSA to be counted as part of the tribe.
2.2 Tribes Eligible to Delineate TDSAs
Every federally recognized tribe without a reservation or off-reservation trust land and
based outside of Alaska, Hawaii and Oklahoma are eligible to update or delineate a
TDSA. Federal recognition of an American Indian tribe specifically means that the tribe
is recognized by and eligible to receive services from the Bureau of Indian Affairs (BIA).
BIA recognition is determined by inclusion of a tribe on the BIA’s list of recognized
tribes or by addenda to the list as published by BIA. If you do have a recognized AIR
and/or ORTL and therefore believe you are not eligible to delineate a TDSA, please
contact your RCC. If the TDSA official declines or defers participation, the Census
Bureau will use the TDSA boundaries delineated for Census 2000, modified as needed to
meet the Census 2010 criteria. If no TDSA was defined for the Census 2000, the Census
Bureau will most likely not delineate one for 2010 without tribal participation.
2.3 Schedule
In fall 2008, the Census Bureau mailed formal invitation letters to tribal officials eligible
to delineate a TDSA. These guidelines and accompanying paper maps required to
complete the work are scheduled to arrive in January 2009. You will have 120 days from
the date you receive these materials to review and submit your TDSA delineations or
updates to the Census Bureau’s RCC. In the fall of 2009, after the Census Bureau has
reviewed and incorporated your TDSA into our geographic database, you will receive
new maps or digital files so that you can verify that we have inserted your boundaries
correctly. If you have questions regarding your delineation or submission, assistance will
be available from geographers at your RCC.
2.4 Program Materials
The paper map types you receive will depend on the size and mapping complexity of
your TDSA. A TDSA that is smaller in land area may only receive a single mapsheet.
TDSAs with large land area may receive an index map, a series of parent maps, and a
number of inset maps. An index map shows the complete TDSA with gridlines defining
specific areas shown on each parent map. A parent map shows a detailed version of a
single grid box from the index map, and an inset map shows finer details of areas within
the parent map where the feature network is too dense to represent clearly at the map

6

scale of the parent sheet. You can think of the inset map as a “blow-up” of a specific
area.

Figure 1: Example of Index, Parent and Inset maps
If your tribe has a Census 2000 TDSA delineation, your map will depict the Census 2000
TDSA boundary with a one mile fringe area. If your updates include area outside of this
fringe area, please contact your RCC for maps depicting this additional area.
If your tribe did not have a Census 2000 TDSA, your RCC will provide county maps for
the area in which the TDSA might be delineated. If the TDSA should be delineated in
counties for which you did not receive maps, please contact the RCC and they will
provide you with the county maps you need. Figure 2 shows entity boundaries that are
shown on your maps and how they are symbolized.

Figure 2: Tribal areas map symbology

The Census Bureau requests that participants use a pencil with red lead to annotate TDSA
boundaries on the paper maps provided. Procedures for annotating the paper maps are
detailed in section 4.
2.5 Important Information on Features
2.5.1 Acceptable Features for Use as TDSA Boundaries
TDSA boundaries should follow specified legal or administrative boundaries that do not
change greatly over time, or permanent, visible features, such as roads, perennial streams,
railroads, and high-tension power lines. Permanent visible features should be easily
locatable in the field by Census Bureau staff without ambiguity. The acceptable visible
boundary features are:
ƒ
ƒ
ƒ
ƒ
ƒ
ƒ
ƒ
ƒ
ƒ
ƒ
ƒ
ƒ
ƒ
ƒ
ƒ
ƒ
ƒ
ƒ
ƒ
ƒ

levee
dam
stream/river (perennial)
canal, ditch or aqueduct (perennial)
pier/dock
runway/taxiway
pipeline (above ground)
powerline (above ground, high-tension)
aerial tramway/ski lift
natural topographic features
cliff/escarpment
perennial shoreline
railroad features (main)
carline, streetcar track, monorail, other mass transit rail
interstate highway or primary road with limited access
primary road without limited access, US highway, state highway or county
highway, secondary and connecting roads
local neighborhood road, rural road, city street
service drive (usually along a limited access highway)
alley
fencelines

Natural topographic features include the crests of well-defined mountain ridges; the rims
or bases of sharply defined escarpments, cliffs, or bluffs; the position of dry ravines or
arroyos; as well as other features as long as the features are not also mimicked by another
visible feature, have no housing in the vicinity, and are easily located on the ground.
Data user and Census Bureau experience has shown that some features make better
boundaries than others, and the same type of feature can make an excellent boundary in
one place and a poor one in another. Rivers, major canals, lakes, and other bodies of
water often make good statistical area boundaries because they generally limit access
from one area to another and rarely change relative location. Other features that limit
access between areas, such as interstate and other major highways, railroad tracks, and
the ridges of mountain ranges, also make good statistical area boundaries. In some
8

instances, however, such a feature unifies a community, for example, a lake forming the
core of a recreational housing development or a through street forming the spine of a
subdivision. In these circumstances, the statistical area boundary should include the entire
area of the lake or both sides of a unifying street to better encompass similar community
patterns.
In general, when delineating boundaries in bodies of water represented as polygons and
having area (lakes, reservoirs, bays, oceans, and wide rivers), the boundary should follow
a line bisecting the water body rather than following a shoreline. If possible, use an
existing line in water (for example, a city limit in the middle of a river) rather than adding
a new line.
Officials delineating TDSAs may only add non-visible lines as a boundary if other
acceptable boundary features such as roads, rivers, streams, shorelines, trails and
ridgelines, are not available and they aid in a TDSA meeting other specific delineation
criteria and/or guidelines. The Census Bureau staff will contact you if they require more
information or have questions about feature updates submitted as part of the 2010 TSAP.
2.5.2 Boundary Feature Updates
The Census Bureau has spent the last six years enhancing the spatial accuracy of the
roads in our database system. The local files used during this project were required to
have an overall average accuracy of 7.6 meters while some files had better accuracy.
Although much of the street network is vastly improved, as you work with our maps you
may notice that in some counties the street and boundary features look distorted. A line
that should be straight may have a noticeable kink or pointed shape. The Census Bureau
is working to correct these problems, and if you need to use a feature that is distorted in
our maps follow the guidelines below.
The Census Bureau is also now moving forward with our 2010 Census field canvassing
and collection activities. This means that we are no longer processing realignments to
our street network. What is critical for the success of the 2010 Census data tabulation is
the location of roads relative to the tabulation entity boundary. As long as the road is
within the correct entity, the population and housing will be properly reported. The
guidelines below also explain what updates are acceptable as part of the TSAP.
It is critical that participants understand that the TSAP is not intended for street feature
updates except where a boundary follows a road (or other visible feature such as a
stream) and the road is not reflected in our file. For this reason the Census Bureau can
not accept street (or other) feature updates that do not follow the guidelines below:
Guidelines for Updating Features
1. If a road is missing and it forms the boundary for the area you are defining, add
the road and provide the name.
2. If you can not correctly delineate the boundary for an entity you are updating
because the feature you need to follow is incorrectly located, mislabeled or
distorted in the Census Bureau’s file, we request that you fix that feature only. In
9

addition, we request that you report the problem area to the Census Bureau
(through your RCC) by sending information describing the incorrect feature and
the specific entity boundary affected.
3. Do not add streets that are missing for an entire housing development (add only
streets that are needed to form a boundary). We will be adding new or missing
streets during our address canvassing operation which will occur in the spring and
early summer of 2009. The Census Bureau will provide verification materials to
each participant that returns their submission in the correct format and within the
allotted 120 days that will show the results of address canvassing. If these streets
are still missing at that time, we will accept these as adds.
2.6 Feature Extension Criteria
If you want to use an existing feature that doesn’t form a closed polygon, you may add a
short line to connect the features and close the polygon. The Census Bureau refers to
these lines as feature extensions and several requirements pertain. To avoid creating
ambiguous Census block boundaries, we require that feature extensions:
ƒ Are no longer than 300 feet;
ƒ Are straight lines from the end of a road and intersecting a non-road feature
(These include all hydrographic features, pipelines, powerlines, and railroads.);
ƒ Do not intersect a cul-de-sac.

3. Criteria
All American Indian Areas (AIAs) must follow a standard set of criteria that support a
shared purpose of providing a meaningful and relevant geographic framework for
tabulating data for the Census. It is the responsibility of the Census Bureau to ensure that
geographic entity criteria can achieve the goal of providing meaningful, relevant, and
reliable statistical data, and that the final criteria for geographic entities are met. While
aware that there are secondary uses of geographic entities and the data tabulated for them,
the Census Bureau will not modify their boundaries or attributes specifically to meet
these secondary uses, including those of other government agencies. If a change is made
to a geographic entity to meet one specific purpose, it may be detrimental for other
programs that also use these entities. The Census Bureau will use the criteria and
guidelines listed below to help ensure that the TDSAs delineated for the 2010 Census
meet their definition, support the intended purpose of the program, provide useful and
meaningful data for the tribe they represent, and enhance the ability of data users to make
more meaningful comparisons between data.
Criteria are rules that must be followed by all officials delineating statistical AIAs for the
2010 Census, while guidelines are suggestions for improving the relevance and utility of
statistical AIAs.
3.1 All Tribal Designated Statistical Areas must follow these criteria:
1. A TDSA must contain some American Indian population and housing.
2. A TDSA may not overlap with any other AIA, at the same level of the geographic
hierarchy.
10

3. A TDSA may not completely surround another legal or statistical AIA at the same
level of the geographic hierarchy.
4. A TDSA may not include more water area than land area.
5. Officials delineating TDSAs may only add nonvisible lines as a boundary if other
acceptable boundary features such as roads, rivers, streams, shorelines, trails and
ridgelines, are not available and they aid in a TDSA meeting other specific,
delineation criteria and/or guidelines.
6. The Census Bureau will evaluate the submitted name to ensure that each TDSAs
name is clearly distinguishable from the name of any other legal or statistical AIA.
7. TDSAs may not include military areas.
8. TDSAs may not be delineated in Hawaii, Oklahoma or Alaska, nor will those existing
in Alaska continue to be recognized.
9. The name of a TDSA will be determined by the tribe or tribes, in conjunction with the
Census Bureau.
10. The name must also reflect one of two conditions: the tribe that has the largest
population currently residing within the TDSA, or the name of the tribe most
commonly associated with the area that the TDSA encompasses.
3.2 All Tribal Designated Statistical Areas should follow these guidelines:
1. TDSAs should be comparable in area to the AIRs and/or ORTLs of other tribes with
similar numbers of members in the same state and/or region.
2. American Indians should constitute a large proportion of the population within a
TDSA, and of the American Indian population, the majority should be members of
the delineating tribe.
3. As a minimum, TDSAs should have a population of 1,200 individuals or 480 housing
units.
4. A TDSA should include an area where there is structured and organized tribal
activity, including tribal headquarters, tribal service centers, meeting areas and
buildings, ceremonial grounds, tribally owned commercial locations, etc.
5. TDSAs should not contain large areas without housing or population. A housing unit
density of at least three housing units per square mile is suggested.
6. TDSAs should be contiguous.
7. Water area should be included only to maintain contiguity, to provide a generalized
version of the shoreline, or if the water area is completely surrounded by land area
included in the TDSA.
8. TDSA boundaries should follow visible, physical features, such as rivers, streams,
shorelines, roads, and ridgelines.
9. TDSA boundaries may follow the nonvisible, legally defined boundaries of AIRs,
ORTLs, states, counties, or incorporated places.
3.3 Things to consider when delineating TDSAs
Since TDSAs also will be used to tabulate and present period estimates from the ACS,
defining officials should consider that, as a general rule, period estimates of demographic
characteristics for geographic entities with small populations will be subject to higher
variances than comparable estimates for geographic entities with larger populations. In
11

addition, the Census Bureau’s disclosure rules may have the effect of restricting the
availability and amount of data for geographic entities with small populations. The more
closely a TDSA’s boundary relates to the distribution of tribal members and American
Indians receiving governmental services from the tribe, and does not include large
numbers of people and households not affiliated with the tribe, the more likely that data
presented for the TDSA will accurately reflect the characteristics of the intended tribal
population.
Although eligible, in a few cases a tribe may elect not to delineate a TDSA if it will not
provide meaningful, relevant, or reliable statistical data because the member population
now resides in numerous other locations or has been completely subsumed by nonmember and/or non-American Indian populations. In such instances, defining a TDSA
will not improve the presentation of statistical data relating to tribal members. These
tribes may still be able to receive meaningful, relevant, and reliable statistical data for
their tribal membership at higher levels of census geography through the characteristic of
tribal affiliation. Both population and housing unit data can be found by accessing
American FactFinder on the Census Bureau’s internet website. Directions for obtaining

4. Procedures
4.1 Annotating Maps
4.1.1 The Census Bureau suggests the following procedures for reviewing and revising an
existing Tribal Designated Statistical Area:
1. Compare your source materials with the Census Bureau’s maps.
2. If you are satisfied with how the TDSA boundary is currently portrayed on the
Census Bureau’s maps, fill out and sign the form attached to the cover letter that
came with your materials, indicating there is “no change” to the boundary. Return the
form to the RCC using the postage paid envelope provided.
3. If you need to change the TDSA boundary, cross out the old boundary with an “X”
using a pencil with red lead. Mark the ends of the deletion with red hatch marks (//).
4. Using a pencil with red lead, plot the revised boundaries on the Census Bureau’s map.
a. Please do not add street or other features unless you are adding a feature
that forms the boundary of your TDSA. The Census Bureau will not
accept new road features at this time unless the road or other feature is
necessary in order to delineate a boundary. Please use a pencil with black
lead to add and label this feature, then use a red pencil to highlight the
feature as a TDSA boundary.
b. If a feature is incorrectly located, mislabeled or distorted on the Census
Bureau’s maps so that you cannot correctly delineate your TDSA
boundary using that feature, please draw your boundary (using the red lead
pencil) following the problematic feature and contact your RCC to
describe the location and nature of the problem.

12

c. Please remember to adjust your TDSA boundary to follow the acceptable
features described in section 2.5.
5. Review the name of the 2000 TDSA. If the name is still appropriate for the TDSA,
make no annotation. If the name requires revision, cross out the old name and clearly
label the new name in red within the boundary of the TDSA.
4.1.2 The Census Bureau suggests the following procedures for delineating a new TDSA:
1. If you do not wish to delineate a TDSA, fill out and sign the form attached to the
cover letter that came with your materials, indicating you do not wish to delineate a
TDSA.
2. Compare your source materials with the Census Bureau’s map(s).
3. Using a pencil with red lead, plot the boundary on the Census Bureau’s map(s).
4. If a feature that is not on the map(s) is required as the boundary of the TDSA, use a
black lead pencil to add and label the new feature and the red pencil to highlight the
feature as a TDSA boundary.
a. Please do not add street or other features unless you are adding a feature
that forms the boundary of your TDSA. The Census Bureau will not
accept new road features at this time unless the road or other feature is
necessary in order to delineate a boundary. Please use a pencil with black
lead to add and label this feature, then use a red pencil to highlight the
feature as a TDSA boundary.
b. If a feature is incorrectly located, mislabeled or distorted on the Census
Bureau’s maps so that you cannot correctly delineate your TDSA
boundary using that feature, please draw your boundary (using the red lead
pencil) following the problematic feature and contact your RCC to
describe the location and nature of the problem.
5. Ensure that the TDSA boundary follows the acceptable feature described in section
2.5.
6. Clearly label the name of the new TDSA in red within the boundary of the TDSA.

4.2 Transmitting Completed Submissions and Census Bureau Review
Please return all maps to the RCC in the same tube/box/envelope you received it in and
be sure to use the mailing label provided. The Census Bureau RCC geographic staff will
verify that the submitted TDSAs are complete, meet all criteria and other requirements
and, where the criteria have not been met, a valid justification is provided.
The Census Bureau will provide feedback to you on your submission, and if necessary
provide additional guidance on the criteria and guidelines usage. The Census Bureau will
contact your tribe with any questions or concerns regarding the submission. The Census
Bureau reserves the right to modify, create, or reject any boundary or attribute as needed
to meet the final program criteria and guidelines, or to maintain geographic relationships
before the tabulation geography is finalized for the 2010 Census.
4.3 Verification
If you return your submissions within 120 days, the Census Bureau will provide you with
a new map which your tribe can use to verify that the Census Bureau staff inserted the
boundary of the TDSA correctly. The verification map will be provided in late 2009. At
that time it would be possible for tribes to make minor boundary changes or add features
that still may be missing from our maps.

Appendix B – Procedures for accessing population and housing unit
data from American FactFinder
1. Starting at the U.S. Census Bureau internet homepage, click on “American FactFinder”
within the list along the left side of the screen.

39

2. On the next page, you will see another list on the left side on the screen. Hover your
mouse over “Data Sets” and then click on “Decennial Census” in the menu that pops up.

40

3. On the next screen, you will have the option of choosing between several different data
sets along with a small description of what each one contains. In this example, we will
access tribal block group data. For block group population data, you should select the
first data set listed which is “Census 2000 Summary File 1.” You may want to scroll
through the other data sets to see what other information is available for your future
reference.

41

4. To extract data, you will now select a number of parameters to identify your area of
interest. Again, in this example we will access tribal block group data, but you can also
access data for reservations, off-reservation trust lands, tracts, blocks and many other
geographic areas.

42

5. Finally, you will select the specific type of data within “Census 2000 Summary File 1”
that you are looking for. Remember that you may select multiple data types.

6. After clicking “Show Result” you will now see the data you have requested.

1. Introduction
The U.S. Census Bureau is the premier source of information about the American people and
the economy. The U.S. Constitution mandates that a census be taken every 10 years in order
to reapportion the House of Representatives. The data gathered by the decennial census and
other Census Bureau programs are used for several other purposes, including the allocation
and distribution of funds to state, local and tribal governments. Census information shapes
important policy decisions that in turn shape the nation’s social and economic conditions.
While best known for the decennial census, the Census Bureau conducts numerous surveys
and censuses that measure changing individual and household demographics and the entire
economic condition of the nation.
Census data help tribal elders and leaders understand what their communities need. Many
tribal communities use census information to attract new business and plan for growth. In
fact, many tribes and tribal organizations use census data to plan new facilities and programs
for the communities they serve.
In preparation for the 2010 Census, the U.S. Census Bureau has developed the Tribal
Statistical Areas Program (TSAP) to collect updates to the inventory and boundaries of
American Indian and Alaska Native statistical geographic areas. Participation in the TSAP is
voluntary, however if your tribe chooses not to participate, the Census Bureau may revise the
boundary of an existing area or delineate a new area in accordance with published criteria
and guidelines. The TSAP includes the following statistical areas:
ƒ
ƒ
ƒ
ƒ
ƒ
ƒ

Alaska Native village statistical areas (ANVSAs)
Oklahoma tribal statistical areas (OTSAs) and tribal subdivisions on OTSAs
state designated tribal statistical areas (SDTSAs)
tribal designated statistical areas (TDSAs)
tribal census tracts (TCTs) and tribal block groups (TBGs) on American Indian
reservations (AIRs)/ off-reservation trust lands (ORTLs)
census designated places (CDPs)

The Census Bureau will tabulate statistical data from the 2010 Census for each entity type
listed above, and will continue to use these areas to provide data from the American
Community Survey (ACS) through the coming decade. Meaningful statistical data from the
2010 Census and ACS provide tribes and other data users with a tool to help them make
informed decisions and plan for community services. More information about the
background and components of these geographic areas can be found in the Federal Register
notice Vol. 73, No. 221 / Friday, November 14, 2008, page 67470. This notice can also be
accessed from our TSAP webpage:
http://www.census.gov/geo/www/tsap2010/tsap2010.html
These guidelines explain the criteria and complete instructions for using paper maps to
review the Census Bureau’s Census 2000 OTSA boundaries and delineate tribal subdivisions
and CDPs within OTSAs. The topics covered are:

Statistical data will be tabulated for all people living within the boundaries of their
geographic areas, and also for all tribal members regardless of where they reside in the state
or nation. Each individual, whether or not he or she is located on a tribal area, will have the
same opportunity to identify their tribal affiliation. While data tabulated for well defined
OTSAs will provide a rich source of statistical and demographic information for your tribe, it
is not necessary for an individual to be living within the boundary of the OTSA to be counted
as part of the tribe. Representation of American Indian statistical boundaries in Census
Bureau products is solely for the purpose of data tabulation and presentation, and does not
convey or confer any rights to land ownership, governmental authority, or jurisdictional
status.
Federally recognized tribes in Oklahoma wishing to update OTSAs and/or delineate OTSA
tribal subdivisions or CDPs will have the option of using paper maps or Census Bureauprovided Geographic Information System (GIS) data, tools, shapefiles, and an ESRI®
ArcGIS® extension specific to this program. Participants who choose to submit changes
using the digital method must have ArcGIS 9.2 or 9.3. These guidelines provide
instructions for to the use of paper maps. There are separate guidelines for the use of the
ESRI extension which are found on the data disc supplied by the Census Bureau.
The TSAP extension, developed by the Census Bureau for ESRI’s ArcMap 9.2, provides a
suite of GIS data management and editing tools/commands designed for participants to
identify, delineate, and review statistical areas. Project inception, quality control, data
submission, and workflow administration are all included in the data management features of
the extension. In addition to the inherent functionality of the ArcGIS software, the
extension’s unique editing tools consist of geographic area assignment, block boundary
definition, tribal tract/tribal block group type attribution, as well as line editing and polygon
split/merge functions. The option of using either the TSAP extension or the paper maps to
submit changes is at the complete discretion of each tribe as neither is preferred over the
other by the Census Bureau. However, depending on the number anticipated updates and/or
their complexity, you might consider using the TSAP extension which offers you the ability
to view population density within American Indian statistical areas and allow you to more
clearly add or remove area or adjust boundaries. If you are interested in using a GIS
application to submit your boundaries and you have ArcGIS 9.2 or 9.3 software, but did not
receive the ArcGIS extension software or digital data files along with your materials, please

other questions or arrange for training.
Disclosures to Respondents
The Geography Division manages programs to continuously update features, boundaries,
addresses, and geographic entities in the Master Address File / Topologically Integrated
Geographic Encoding and Referencing System (MAF/TIGER) database (MTdb) that is used
to support programs and to conduct the census and surveys. The TSAP program was
developed to give tribes the opportunity to review and update, if necessary, statistical tribal
entities for use in tabulating and publishing data from the 2010 Census, the American
Community Survey, and other surveys.
Public reporting burden for this collection of information is estimated to average 48 hours per
respondent, including time for reviewing instructions, assembling materials, organizing and
reviewing the information, and reporting any needed changes. We anticipate that an
estimated 650 participants will respond. Remaining entities may be worked by Census
Bureau regional staff. For larger areas or areas with many changes, however, the respondent
burden may be 180 hours or longer to complete. Please send comments regarding this
burden estimate or any other aspect of this collection of information, including suggestions
for reducing this burden to:

2. Background on OTSA Tribal Statistical Areas
2.1.1 OTSAs
OTSAs are statistical areas identified and delineated by the Census Bureau and federally
recognized tribes based in Oklahoma that had a former American Indian Reservation (AIR)
in Oklahoma. OTSAs are intended to represent the former AIRs that existed in the Indian
and Oklahoma territories prior to Oklahoma statehood in 1907. They provide comparable
1

See Appendix C for RCC contact information.

3

geographic entities for analyzing data over time, and a way to obtain data comparable to that
provided to federally recognized tribes that currently have an AIR. Because all former AIRs
in Oklahoma were delineated for Census 2000, the Census Bureau does not expect any new
OTSAs for the 2010 Census. As part of the TSAP, the Census Bureau is providing your tribe
with the opportunity to review the boundary and name of the Census 2000 OTSA. In
addition, your tribe may opt to identify or revise tribal subdivisions and census designated
places within the Census 2000 OTSA.
2.1.2 Off Reservation Trust Lands
The Census Bureau is aware that federally recognized tribes in Oklahoma have trust lands
throughout the state. As part of the TSAP, a tribe may choose to have the Census Bureau
tabulate data for its ORTL for the 2010 Census. This can be implemented if the tribe can
supply an acceptable Geographic Information System file or map(s) and the required
supporting legal documentation for the Census Bureau to use to record the ORTL accurately.
If a tribe chooses to submit their ORTL to the Census Bureau, the tribe’s ORTL will be
excluded from the OTSA. The trust land areas will then become part of the universe of
legally defined entities updated and maintained through the Census Bureau’s annual
Boundary and Annexation Survey (BAS). Contact your RCC for more information on
reporting ORTLs and the BAS (See section 2.3).
2.1.3 Joint Use Areas
For previous censuses, the Census Bureau allowed the boundaries of OTSAs to deviate
somewhat from the corresponding former AIR boundaries when requested by a tribe and
supported by available demographic data. Such deviations affect the delineation and
identification of other tribes’ OTSAs, resulting in area being associated with multiple
OTSAs. These areas with multiple relationships were defined as separate geographic entities
and identified as “joint use area OTSAs” for Census 2000. In response to comments received
from data users, especially with regard to federal laws and programs requiring the use of the
former AIR boundaries rather than OTSA boundaries, the Census Bureau would like TSAP
participants to workto dissolve the existing OTSA joint use areas. If tribes can not come to
agreement on how to eliminate these areas, we will allow the existing Census 2000 Joint Use
Areas to remain, but will not approve any new ones for 2000. Four joint use area OTSAs
were created for Census 2000:
ƒ
ƒ
ƒ
ƒ

Kiowa-Comanche-Apache-Ft. Sill Apache-Caddo-Wichita-Delaware
Creek-Seminole
Kaw-Ponca
Miami-Peoria.

2.1.4 Tribal Subdivisions
Tribal subdivisions are units of self government and/or administration within an AIR and/or
ORTL for a federally recognized tribe or within an OTSA, that serve social, cultural, and/or
legal purposes for the tribal government. Tribal subdivisions delineated within an AIR or
ORTL are considered “legal geographic entities” by the Census Bureau and, thus, are
specifically termed “legal tribal subdivisions.” These are delineated or updated through the
annual BAS (See section 2.3). Tribal subdivisions delineated within OTSAs are considered
4

‘‘statistical geographic entities’’ by the Census Bureau and are specifically termed
‘‘statistical tribal subdivisions’’ because the larger OTSA is also considered a statistical
geographic entity. They are delineated or updated with the OTSAs through the TSAP. If
delineated, OTSA tribal subdivisions should completely cover all of an OTSA. Separate,
discrete communities whose boundaries encompass a concentration of population and
housing should be identified as a CDP rather than a tribal subdivision (see section 2.1.5).
The Census Bureau tabulates data for only one level of tribal subdivision within an AIR,
ORTL, or OTSA. Tribes that have multiple hierarchical levels of administrative units (for
example, water districts that nest within councilmen districts) should submit the unit with the
smallest geographic area (the water districts using our example) so that their data can be
aggregated if desired for the larger geographic area. The Census Bureau will identify each
tribal subdivision in its data products with the name and administrative unit type (chapter,
district, etc.) submitted by the defining tribal government. The name of each tribal
subdivision must reflect its name, as cited in recent tribal legal documentation and/or used by
the tribal government for administrative purposes.
2.1.5 Census Designated Places
CDPs are statistical geographic areas representing closely settled, unincorporated
communities, which are locally recognized and identified by name. They are the statistical
equivalents of incorporated places, with the primary differences being the lack of both a
legally defined boundary and an active, functioning governmental structure, chartered by the
state and administered by elected officials. CDPs encompass a concentration of population,
housing, and commercial structures that are clearly identifiable by a single name, but are not
within an incorporated place. The primary goal of CDPs is to map a boundary for and
provide meaningful statistics for well-known, unincorporated localities. A CDP generally
consists of a contiguous cluster of census blocks comprising a single piece of territory and
containing a mix of residential and commercial uses similar to that of an incorporated place
of similar size. Some CDPs, however, may be predominantly residential; such places should
represent recognizably distinct, locally known communities, but not typical suburban
subdivisions. A CDP may not be located, either partially or entirely, within an incorporated
place or another CDP.
CDPs are delineated through both the TSAP and the Participant Statistical Areas Program
(PSAP) for the 2010 Census. Federally recognized tribes with AIRs, ORTLs, or OTSAs may
update or delineate new CDPs within the boundary of their reservation, trust land, or OTSA
through the TSAP. Tribes that would like to delineate CDPs for communities completely off
their legal or statistical area should work with the PSAP primary participants for the areas in
which they are interested. Contact the Kansas City RCC (See Appendix C) for more
information.

5

2.2 Tribes Eligible to Delineate OTSAs
Federally recognized tribes based in Oklahoma that had a former AIR in Oklahoma are
invited to review their 2000 OTSA boundary and update or delineate tribal subdivisions
within the OTSA boundary. These tribes are also eligible to delineate CDPs. Federal
recognition of an American Indian tribe specifically means that the tribe is recognized by and
eligible to receive services from the Bureau of Indian Affairs (BIA). BIA recognition is
determined by inclusion of a tribe on the BIA’s list of recognized tribes or by addenda to the
list as published by the BIA. If for any reason, you believe you should not be updating an
OTSA or OTSA tribal subdivision and should be delineating or updating another type of
American Indian Area (or if you have a federally recognized reservation or off-reservation
trust lands), please contact the Kansas City RCC. If the OTSA official declines or defers
participation, the Census Bureau will use the Census 2000 boundaries, possibly modifying it
to meet 2010 OTSA criteria, and will not likely define any tribal subdivisions or CDPs within
the OTSA.
2.3 The Boundary and Annexation Survey
The Boundary and Annexation Survey (BAS) is an annual Census Bureau survey of legal
geographic entities that includes federal AIRs, ORTLs, and any associated tribal
subdivisions. Whereas the TSAP provides the process for reviewing and updating those
AIAs that are statistical geographic entities (TCTs, TBGs, and CDPs), the BAS provides the
process for reviewing and updating AIAs that are legal federal geographic entities, such as
the reservation itself, tribal subdivisions and ORTLs. Its purpose is to determine, solely for
data collection and tabulation by the Census Bureau, the complete and current inventory and
the correct names, legal descriptions, official status, and official, legal boundaries of the legal
geographic entities with governmental authority over certain areas within the United States,
as of January 1 of the survey year. The BAS also collects specific information to document
the legal actions that established a boundary or imposed a boundary change. In support of
the government-to-government relationship with federally recognized American Indian
tribes, the Census Bureau works directly with tribal officials on the BAS. Through the BAS,
the Census Bureau also accepts updates to features such as roads or rivers, and address range
break information at the boundaries. If you wish to update boundaries for you reservation,
off-reservation trust lands or legal tribal subdivisions, you should do so through the BAS.
For more information about the BAS, contact your RCC or see the Census Bureau's website
at http://www.census.gov/geo/www/bas/bashome.html. The BAS Respondent
Guide for federally recognized tribes is available at:
http://www.census.gov/geo/www/bas/bas09/bas09_mat_aia.html
2.4 Schedule
In October 2008, the Census Bureau mailed formal invitation letters to tribal officials of each
eligible OTSA. These guidelines accompany the paper maps required to complete the work.
Tribes will have 120 days from the date they receive these materials to review and submit
their geographic statistical area delineations or updates to the RCC. In late 2009, after the
Census Bureau has reviewed and incorporated your delineations into our geographic
database, you will receive new maps or digital files so that you can verify that we have
6

inserted your boundaries correctly. If you have questions regarding your delineation or
submission, assistance will be available from geographers at the Kansas City RCC.
2.5 Program Materials
The paper map types you receive will vary depending on the size and mapping complexity of
your OTSA. An OTSA that is smaller in land area may only receive a few index and parent
maps. OTSAs with a larger land area may receive an index map, a series of parent maps, and
a number of inset maps. An index map shows the complete OTSA with gridlines defining
specific areas shown on each parent map. A parent map shows a detailed version of a single
grid box from the index map and an inset map shows finer details of areas within the parent
map where the feature network is too dense to represent clearly at the map scale of the parent
sheet. You can think of the inset map as a “blow-up” of a specific area.

Figure 1: Example of Index, Parent and Inset maps

Figure 2: TSAP map symbology

7

Figure 2 shows all the boundaries that may be shown on your map and how they will be
symbolized. The Census Bureau requests that participants use a pencil with purple lead to
annotate OTSA tribal subdivisions and a red pencil to delineate CDP boundaries on the paper
maps provided. Since OTSAs are based on the historical former reservation boundary, the
boundaries should not change from what was used in Census 2000. If you think there is a
problem with those boundaries contact the Kansas City RCC.
2.6 Important Information on Features
2.6.1 Acceptable Features for use as boundaries
Statistical area boundaries should follow specified legal or administrative boundaries that do
not change greatly over time, or permanent, visible features, such as roads, perennial streams,
railroads, and high-tension power lines. Permanent visible features should be easily locatable
in the field by Census Bureau staff without ambiguity. The acceptable visible boundary
features are
ƒ
ƒ
ƒ
ƒ
ƒ
ƒ
ƒ
ƒ
ƒ
ƒ
ƒ
ƒ
ƒ

levee
dam
stream/river (perennial)
canal, ditch or aqueduct (perennial)
pier/dock
runway/taxiway
pipeline (above ground)
powerline (above ground, high-tension)
aerial tramway/ski lift
natural topographic features
cliff/escarpment
perennial shoreline
railroad features (main)
carline, streetcar track, monorail, other mass transit rail
interstate highway or primary road with limited access
primary road without limited access, US highway, state highway or county highway,
secondary and connecting roads
local neighborhood road, rural road, city street
service drive (usually along a limited access highway)
alley
fencelines

Natural topographic features include the crests of well-defined mountain ridges; the rims or
bases of sharply defined escarpments, cliffs, or bluffs; the position of dry ravines or arroyos;
as well as other features as long as the features are not also mimicked by another visible
feature, have no housing in the vicinity, and are easily located on the ground.
Data user and Census Bureau experience has shown that some features make better
boundaries than others, and the same type of feature can make an excellent boundary in one
place and a poor one in another. Rivers, major canals, lakes, and other bodies of water often
8

make good statistical area boundaries because they generally limit access from one area to
another and rarely change relative location. Other features that limit access between areas,
such as interstate and other major highways, railroad tracks, and the ridges of mountain
ranges, also make good statistical area boundaries. In some instances, however, such a
feature unifies a community, for example, a lake forming the core of a recreational housing
development or a through street forming the spine of a subdivision. In these circumstances,
the statistical area boundary should include the entire area of the lake or both sides of a
unifying street to better encompass similar community patterns.
In general, when delineating boundaries in bodies of water represented as polygons and
having area (lakes, reservoirs, bays, oceans, and wide rivers), the boundary should follow a
line bisecting the water body rather than following a shoreline. Whenever possible, use an
existing line in water (for example, a county line in the middle of a river) rather than adding a
new line.
2.6.2 Boundary Feature Updates
The Census Bureau has spent the last six years enhancing the spatial accuracy of the roads in
our database system. The local files used during this project were required to have an overall
average accuracy of 7.6 meters with some files having better accuracy.
Although much of the street network is vastly improved, as you work with our maps you may
notice that in some counties the street and boundary features look distorted. A line that
should be straight may have a noticeable kink or pointed shape. The Census Bureau is
working to correct these problems, therefore if you need to use a feature that is distorted,
follow the guidelines in section 4.2.
The Census Bureau is now moving forward with our 2010 Census field canvassing and
collection activities. This means that we are no longer processing realignments to our street
network. What is critical for the success of the 2010 Census data tabulation is the location of
roads relative to the tabulation entity boundary. As long as the road is within the correct
entity, the population and housing will be properly reported. The guidelines in section 4.2
also explain what feature updates are acceptable as part of the TSAP.
The Census Bureau staff will contact you if they require more information or have questions
about feature updates submitted as part of our 2010 TSAP.
2.7 Feature Extension Criteria
If you want to use an existing feature that doesn’t form a closed polygon, you may add a
short line to connect the features and close the polygon. The Census Bureau refers to these
lines as feature extensions and several requirements pertain. To avoid creating ambiguous
Census block boundaries, we require that feature extensions:
ƒ Are no longer than 300 feet;
ƒ Are straight lines from the end of a road and intersecting a non-road feature (These
include all hydrographic features, pipelines, powerlines, and railroads.);
ƒ Do not intersect a cul-de-sac.

3. Criteria and Guidelines for OTSAs, tribal subdivisions on OTSAs and
CDPs
All American Indian Areas (AIAs) must follow a standard set of criteria that support a shared
purpose of providing a meaningful and relevant geographic framework for tabulating data for
the Census. It is the responsibility of the Census Bureau to ensure that geographic entity
criteria can achieve the goal of providing meaningful, relevant, and reliable statistical data,
and that the final criteria for geographic entities are met. While aware that there are
secondary uses of geographic entities and the data tabulated for them, the Census Bureau will
not modify their boundaries or attributes specifically to meet these secondary uses, including
those of other government agencies. If a change is made to a geographic entity to meet one
specific purpose, it may be detrimental for other programs that also use these entities.
The Census Bureau will use the following criteria and guidelines for the 2010 Census.
Criteria are rules that must be followed by all officials delineating statistical AIAs for the
2010 Census, while guidelines are the Census Bureau’s suggested approach for improving
the relevance and utility of statistical AIAs. Because OTSA boundaries are based on the
historical boundaries of former reservations, they should not change from the boundaries
used in the 2000 Census. If you feel the 2000 boundaries are not correct, please contact the
Kansas City RCC.
3.1 The OTSA criteria are:
1. An OTSA must contain some American Indian population and housing.
2. An OTSA may not include more water area than land area.
3. OTSAs must be located completely within the current boundaries of the state of
Oklahoma.
4. OTSAs must follow the last legal boundaries established for their former AIR.
5. An OTSA may not completely surround another legal or statistical area at the same level
of the geographic hierarchy.
6. The name for each OTSA is determined by the tribe or tribes (in conjunction with the
Census Bureau) that are responsible for delineating each OTSA, and must be clearly
distinguishable from the name of any other OTSA. The Census Bureau will revise any
name submitted for an OTSA if the name does not reflect one or more of the following
conditions:
a. The tribe or tribes associated with the former AIR represented by the OTSA;
b. Tribes that have historically resided within the area of the OTSA;
c. Tribes that have significant population currently residing within the OTSA;
and/or
d. The name(s) of the tribe(s) commonly associated with the area encompassed
by the OTSA.
3.2 Guidelines for delineating OTSAs are:
1. To the extent possible, OTSA boundaries identified for the 2010 Census should be the
same as those delineated for Census 2000.
2. Tribes should strive to eliminate overlapping OTSA boundaries that resulted in the
Census 2000 joint use area OTSAs.
3. Tribes may delineate tribal subdivisions within their own OTSAs.
10

4. Tribes may delineate CDPs representing unincorporated communities located within their
own OTSAs.
3.3 Guidelines for delineating tribal subdivisions within OTSAs are:
1. OTSA tribal subdivisions should represent units of self-government or administration
within an AIR or ORTL for a federally recognized tribe.
2. OTSA tribal subdivisions are intended to completely cover all of an OTSA.
3. The name of each tribal subdivision must reflect the name cited in recent tribal legal
documentation and/or used by the tribal government for administrative purposes.
4. If an OTSA consists of multiple, noncontiguous parts, the tribal subdivisions within them
will be noncontiguous.

3.4 The census designated place criteria are:
1. CDPs cannot be coextensive with an entire OTSA, AIR, or any other AIA.
2. CDPs may extend off OTSAs.
3. A CDP may not have the same name as an adjacent or nearby incorporated place.
4. A CDP may be located in more than one county but must not cross state boundaries.
5. A CDP may not be located, either partially or entirely, within an incorporated place or
another CDP.
3.5 Guidelines for delineating census designated places are:
1. A CDP constitutes a single, closely settled center of population that is named. To the
extent possible, individual unincorporated communities should be identified as separate
CDPs.
2. A CDP is defined to provide data for a single named locality, therefore the Census
Bureau does not encourage delineating CDPs that comprise a combination of places or
are identified by hyphenated names. For example, CDPs such as Poplar-Cotton Center
and Downieville-Lawson-Dumont are no longer acceptable. Prior to Census 2000
communities were sometimes combined as a single CDP in order to comply with the
Census Bureau minimum population requirements. The Census Bureau’s elimination of
population threshold criteria has made such combinations unnecessary.
3. Multiple communities may only be combined to form a single CDP when the identities of
these communities have become so intertwined that the communities are commonly
perceived and referenced as a single place.
4. Multiple communities also may be defined as a single CDP when there is no
distinguishable or suitable feature in the landscape that can be used as a boundary
between the communities, even if the two communities still have separate identities.
5. There is no minimum population or housing unit thresholds for defining CDPs; however,
a CDP must contain some population or housing units or both. Participants submitting
boundaries for places with less than ten housing units may be asked to provide additional
information attesting to the existence of the CDP.
6. CDP boundaries should follow the features, outlined in section 2.5. CDP boundaries may
follow other nonvisible features in instances where reliance upon visible features will
result in over bounding of the CDP and the intent is to include housing units on both

11

sides of a road or street feature. Such nonvisible lines might include parcel boundaries
and public land survey system lines; national, state, or local park boundaries.
7. The CDP name should be one that is recognized and used in daily communication by the
residents of the community.
8. A CDP should have population during at least one entire season of the year, and have a
higher housing unit and population density than surrounding areas.
If you need to define a CDP that is outside of your OTSA boundary, please contact the
Kansas City RCC. Both population and housing unit data can be found by accessing
American FactFinder on the Census Bureau’s internet website. Directions for obtaining this
data can be found in Appendix B.

4. Procedures
4.1 Review of Statistical Areas
The Census Bureau suggests the following procedures for reviewing and delineating OTSAs,
tribal subdivisions within OTSAs and CDPs.
1. Compare your source materials with the Census Bureau’s maps.
2. If you are satisfied with the OTSA name and how the OTSA boundary is currently
portrayed on the Census Bureau’s maps and you do not wish to update or delineate any
tribal subdivisions within your OTSAs nor do you want to delineate or revise any CDPs,
fill out and sign the form attached to the cover letter that came with your materials
indicating “no change.” Return the form to the RCC using the postage paid envelope
provided.
3. If you believe the OTSA boundary or name needs to be changed or corrected, contact the
Kansas City RCC to discuss your recommended change.
4.2 Annotation of maps:
1. If you need to update or delineate new OTSAs, tribal subdivisions on OTSAs or CDPs,
use a pencil with purple lead to plot revised OTSA and OTSA tribal subdivision
boundaries and a pencil with red lead to plot CDP boundaries on the Census Bureau’s
map.
a. Please do not add street or other features unless you are adding a feature that
forms the boundary of your OTSA tribal subdivision or CDP. The Census
Bureau cannot accept new road features at this time. If you must add a road
or other feature in order to delineate a boundary, please use a black lead pencil
to add and label this feature, then use the purple or red pencil to highlight the
feature as a boundary.
b. If a feature is incorrectly located, mislabeled or distorted on the Census
Bureau’s maps so that you cannot correctly delineate your boundary using that
feature, please draw your boundary (using the purple or red pencil) following
the problematic feature and contact the Kansas City RCC to describe the
location and nature of the problem.

12

c. Please remember to adjust your OTSA tribal subdivision or CDP boundary to
follow the acceptable features described under the “Acceptable Boundary
Features” section.
4. Add any new features first in black and plot your tribal subdivision and/or CDP
boundaries adjacent to the black lead pencil line.
5. Review the name of the Census 2000 OTSA, tribal subdivision, or CDP. If the name is
still appropriate for the OTSA, make no annotation. If the name requires revision, cross
out the old name and clearly label the new name in purple (for tribal subdivisions) or red
(for CDPs) within the boundary of the OTSA. The Census Bureau will evaluate the
submitted name of each OTSA to ensure that the name is clearly distinguishable from the
name of any other OTSA.
Example

Figure 3: In this example, a new CDP has been delineated on an existing OTSA.
4.3 Transmitting completed submissions and Census Bureau review
13

Please return all maps to the RCC in the same tube/box/envelope you received it in and be
sure to use the mailing label provided. The Census Bureau RCC geographic staff will verify
that the submitted OTSAs are complete, meet all criteria and other requirements and, where
the criteria have not been met, a valid justification is provided.
The Census Bureau will provide feedback to the participant on their submission, and if
necessary provide additional guidance on the criteria and guidelines usage. The Census
Bureau will contact your tribe with any questions or concerns regarding the submission. The
Census Bureau reserves the right to modify, create, or reject any boundary or attribute as
needed to meet the final program criteria and guidelines, or to maintain geographic
relationships before the tabulation geography is finalized for the 2010 Census.
4.4 Verification
If you return your submissions within 120 days, the Census Bureau will provide you with a
new map which your tribe can use to verify that the Census Bureau staff inserted the
boundary of the OTSA correctly. The verification map will be provided in late 2009. At that
time it would be possible for tribes to make minor boundary changes or add features that still
may be missing from our maps.

OMB No. 0607-0795: Approval Expires 03/31/09

1. Introduction
The U.S. Census Bureau is the premier source of information about the American people
and the economy. The U.S. Constitution mandates that a census be taken every 10 years
in order to reapportion the House of Representatives. The data gathered by the decennial
census and other Census Bureau programs are used for several other purposes, including
the allocation and distribution of funds to state, local and tribal governments. Census
information shapes important policy decisions that in turn shape the nation’s social and
economic conditions. While best known for the decennial census, the Census Bureau
conducts numerous surveys and censuses that measure changing individual and
household demographics and the entire economic condition of the nation.
Census data help tribal elders and leaders understand what their communities need.
Many tribal communities use census information to attract new business and plan for
growth. In fact, many tribes and tribal organizations use census data to plan new
facilities and programs for the communities they serve.
In preparation for the 2010 Census, the U.S. Census Bureau has developed the Tribal
Statistical Areas Program (TSAP) to collect updates to the inventory and boundaries of
American Indian and Alaska Native statistical geographic areas. Participation in the
TSAP is voluntary; however, if your village chooses not to participate, the Census
Bureau may update the boundary of an existing area or delineate a new area in
accordance with published criteria and guidelines. TSAP includes the following
statistical areas:
ƒ
ƒ
ƒ
ƒ
ƒ
ƒ

Alaska Native village statistical areas (ANVSAs)
Oklahoma tribal statistical areas (OTSAs) and tribal subdivisions on OTSAs
state designated tribal statistical areas (SDTSAs)
tribal designated statistical areas (TDSAs)
tribal census tracts (TCTs) and tribal block groups (TBGs) on American Indian
reservations (AIRs)/ off-reservation trust lands (ORTLs)
census designated places (CDPs)

The Census Bureau will tabulate statistical data from the 2010 Census for each of the
entities listed above, and will continue to use these areas to provide data from the
American Community Survey (ACS). Through the coming decade, meaningful statistical
data from the 2010 Census and ACS can provide villages and other data users with a tool
to help make informed decisions and plan for community services. More information
about the background and components of these geographic areas can be found in the
Federal Register notices Vol. 73, No. 221 / Friday, November 14, 2008, page 67470 and
Vol. 73, No. 214 / Tuesday, November 4, 2008, page 65572. These notices can also be
accessed from our TSAP webpage:
http://www.census.gov/geo/www/tsap2010/tsap2010.html.

These guidelines contain the criteria and instructions for delineating ANVSAs and cover
the following topics:
ƒ Background on ANVSAs
ƒ Villages eligible to delineate ANVSAs
ƒ Schedule
ƒ Required materials
ƒ ANVSA criteria
ƒ Procedures for annotating maps
ƒ Procedures for transmitting completed submissions
ƒ Census Bureau submission review
ƒ Verification
Tribes wishing to delineate ANVSAs will have the option of using paper maps or Census
Bureau-provided Geographic Information System (GIS) data, tools, shapefiles, and an
ESRI® extension specific to this program. Participants who chose to submit changes
using the digital method must have ArcGIS® 9.2 or 9.3. These guidelines provide
instructions for submitting ANVSAs using paper maps. There are separate
guidelines for use of the ESRI extension to delineate ANVSAs. These are found in
the data disc supplied by the Census Bureau.
The TSAP Extension, developed by the Census Bureau for ESRI’s ArcMap 9.2, provides
a suite of GIS data management and editing tools/commands designed for participants to
identify, delineate, and review statistical areas. Project inception, quality control, data
submission, and workflow administration are all included in the data management
features of the extension. In addition to the inherent functionality of the ArcGIS
software, the extension’s unique editing tools consist of geographic area assignment, as
well as line editing and polygon split/merge functions. The option of using either the
TSAP extension or the paper maps to submit changes is at the complete discretion of
each tribe as neither is preferred over the other by the Census Bureau. However,
depending on the number anticipated updates and/or their complexity, you might consider
using the TSAP extension which offers you the ability to view population density within
American Indian statistical areas and allow you to more clearly add or remove area or
adjust boundaries.
If you are interested in using a GIS application to submit your boundaries and you have
ArcGIS 9.2 or 9.3 software, but did not receive the ArcGIS extension software or digital
data files along with your materials, please contact the Seattle Regional Census Center
(RCC). You may also contact RCC staff to ask other questions or arrange for training.
Disclosures to Respondents
The Geography Division manages programs to continuously update features, boundaries,
addresses, and geographic entities in the Master Address File / Topologically Integrated
Geographic Encoding and Referencing System (MAF/TIGER) database (MTdb) that is
used to support programs and to conduct the census and surveys. The TSAP program was
developed to give tribes the opportunity to review and update, if necessary, statistical

4

tribal entities for use in tabulating and publishing data from the 2010 Census, the
American Community Survey, and other surveys.
Public reporting burden for this collection of information is estimated to average 48 hours
per respondent, including time for reviewing instructions, assembling materials,
organizing and reviewing the information, and reporting any needed changes. We
anticipate that an estimated 650 participants will respond. Remaining entities may be
worked by Census Bureau regional staff. For larger areas or areas with many changes,
however, the respondent burden may be 180 hours or longer to complete. Please send
comments regarding this burden estimate or any other aspect of this collection of
information, including suggestions for reducing this burden to:
Paperwork Project
0607-0795
U.S. Census Bureau
4600 Silver Hill Road
Room 3K138
Washington, D.C. 20233
You may e-mail comments to [email protected]. Use “Paperwork Project 06070795” as the subject.
Responses to this survey are voluntary. The authority for conducting these activities is
covered under the legal authority of Title 13 U.S.C. Sections 141 and 193.
No agency may conduct and no person may be required to respond to a collection of
information unless it displays a valid Office of Management and Budget (OMB) approval
number. The OMB approval number for this information collection is 0607-0795.

2. Background on ANVSAs
2.1 Purpose of an ANVSAs
ANVSAs are defined so that the Census Bureau can produce statistical data for each
Alaska Native village (ANV). ANVSAs are statistical geographic entities representing
permanent and/or seasonal residences of Alaska Natives who are members of or receive
governmental services from the defining ANV, and we are located within the region and
vicinity of the ANV’s historic and/or traditional location. ANVSAs are intended to
represent the relatively densely settled portion of each ANV and should include only an
area where Alaska Natives, especially members of the defining ANV, represent a
substantial proportion of the population during at least one season of the year. ANVSAs
should not contain large areas that are primarily unpopulated or that do not include
concentrations of Alaska Natives. An ANVSA should include housing, cultural and
commercial structures. ANVSAs are not necessarily meant to portray traditional lands,
and their depiction on Census Bureau products is not intended to convey any rights to
land ownership, governmental authority, or jurisdictional status.

5

Boundaries for Alaska Native Village statistical areas (ANVSAs) were first determined
for the 1990 Census of Population and Housing. The 1990 ANVSAs were then reviewed
and if needed, revised prior to Census 2000. As part of the 2010 Census TSAP, Alaska
Native village (ANV) officials will again have the opportunity to review and confirm or
if needed to update the boundaries of their existing ANVSAs or if appropriate delineate
new ANVSAs. If the ANV official declines or defers participation, or does not respond
to the Census Bureau invitation to participate, we will request that the associated village
or group corporation work with us to define the ANVSA. If the village or group
corporation is also unable or unwilling to define the ANVSA, the Census Bureau will
work with the Alaska Native Regional Corporation (ANRC) non-profit association in
whose region the ANV is located (see Appendix A for a list showing ANV to ANRC
relationships). If the Census Bureau receives no reply from any of these entities, the
Census Bureau may delineate or revise the ANVSA, to meet the criteria outlined in this
document. In some cases, an ANV official may elect not to delineate an ANVSA if it
will not provide meaningful, relevant, or reliable statistical data. This would be
appropriate if the member population now resides in other places or has been completely
subsumed by non-member and/or non-Native populations.
The Census Bureau will tabulate statistical data for all people living within the
boundaries of an ANVSA (including non-village members), and also for all village
members regardless of where they reside in the state or nation. Each household
completing the Census questionnaire has the opportunity to identify the race of each
person living in the house. For each person who identifies their race as American Indian
or Alaska Native, they can then list their village as the enrolled or principle tribe. While
data tabulated for a well defined ANVSA will provide a rich source of statistical and
demographic information about an ANV, it is not necessary for an individual to be living
within the boundary of the ANVSA to be counted as part of the village.
2.2 Villages Eligible to Delineate ANVSAs
Any ANV that is recognized by or eligible to receive services from the Bureau of Indian
Affairs (BIA) or that is recognized under the Alaska Native Claims Settlement Act
(ANCSA) as either a Native village or Native group may delineate an ANVSA. BIA
recognition is determined by inclusion of an ANV on the BIA’s list of recognized tribes
or by addenda to the list as published by the BIA. ANVSA recognition is determined by
inclusion on the Bureau of Land Management’s (BLM’s) list of ANCSA recognized
Native villages and Native groups. There are no population requirements for defining an
ANVSA. A list of ANVs that are eligible to delineate ANVSAs has been included in
Appendix A. The following three tribes in Alaska recognized by the BIA would not be
eligible to be represented by ANVSAs because they are not ANVs, are large regional
tribal associations, or have a legally defined American Indian Reservation: Central
Council of the Tlingit and Haida Indian Tribes, Inupiat Community of the Arctic Slope,
and Metlakatla Indian Community Annette Island Reserve. Also, the former Tetlin
TDSA is now an ANVSA and the Kamatak TDSA has been removed.

6

2.3 Schedule
In October 2008, the Census Bureau mailed formal invitation letters to village officials of
each eligible ANV. These guidelines accompany the paper maps required to complete
the work. Participants have 120 calendar days from the date they receive these materials
to review existing boundaries or delineate new ANVSA boundaries and must submit their
revisions or new boundary definitions to the Census Bureau’s Seattle RCC 1 within that
time. In fall 2009, after the Census Bureau has reviewed and incorporated your
delineations into our geographic database, you will receive new maps or digital files so
that you can verify that we have inserted your boundaries correctly. If you have
questions regarding your delineation or submission, assistance will be available from
geographers at the Seattle RCC.
2.4 Program Materials
If a village has a Census 2000 ANVSA delineation, the Seattle RCC is providing:
ƒ A map depicting the Census 2000 ANVSA area boundary with a one-mile
fringe area.
ƒ A map showing a point location of the ANV and a 50 mile radius area around
the point.
ƒ A map of the ANRC in which the ANV is located.
If a village did not have a Census 2000 ANVSA, the Seattle RCC will provide:
ƒ A map showing the latitude and longitude coordinate location of the ANV and
a 50 mile radius around that point.
ƒ A map of the ANRC in which the ANV is located.
The point locations provided on the maps represent each eligible ANV, as determined by
the Census Bureau. Each point location has been verified using the ANRC boundaries,
the USGS Geographic Names Information System (GNIS) point locations, USGS
topographic maps, location information from previous censuses, BLM Core Townships,
ANCSA 14(c) survey plats, location information from the State of Alaska, and Native
allotment boundaries. The latitude and longitude coordinates listed for an ANV provide
the starting point for delineation of that ANVSA. Each ANVSA must primarily include
land immediately surrounding the corresponding point locations, but may include
additional territory according to the other final program criteria and guidelines.
All ANV point location maps and ANRC maps will be a single map sheet. If you had a
Census 2000 ANVSA delineation, the ANVSA area map types you receive will depend
on the size and complexity of your ANVSA. An ANVSA that is smaller in land area may
only receive a single map sheet. ANVSAs with a large land area may receive an index
map, a series of parent maps and a number of inset maps. An index map shows the
complete ANVSA with gridlines defining specific areas shown on the parent map. A
parent map shows a detailed version of a single grid box from the index map and an inset
map shows finer details of areas within the parent map where the feature network is too
dense to clearly represent at the map scale of the parent sheet. You can think of the inset
1

See Attachment E for contact information for the Regional Census Centers

map as a “blow up” of a specific area. ANRC maps are provided as a reference map.
ANVSA updates and revisions should be annotated on the ANVSA parent or inset maps.

Figure 1: Example of Index, Parent and Inset maps

Figure 2: This image shows all the boundaries that may appear on your ANVSA maps
and how they are symbolized.
If you would like to use Census 2000 data, such as total population or housing units, in
the delineation of your ANVSA, you may contact the Seattle RCC or go to American
FactFinder on the Census Bureau website (http://www.census.gov/). Detailed
instructions for using American FactFinder can be found in Appendix D.
2.5 Important Information on Features
2.5.1 Acceptable features for use as ANVSA boundaries

8

ANVSA boundaries should follow specified legal or administrative boundaries that do
not change greatly over time. Examples of these legal or administrative census areas
boundaries are:
ƒ
ƒ
ƒ
ƒ
ƒ
ƒ
ƒ
ƒ

American Indian reservation
Off-reservation trust land
Tribal subdivision
County
County subdivision
Boroughs
Incorporated places
Alaska Native Regional Corporations

Statistical area boundaries may also follow permanent, visible features, such as roads,
perennial streams, railroads, and high-tension power lines. Permanent visible features
should be easily locatable in the field by Census Bureau staff without ambiguity. The
acceptable visible boundary features are:
ƒ
ƒ
ƒ
ƒ
ƒ
ƒ
ƒ
ƒ
ƒ
ƒ
ƒ
ƒ
ƒ
ƒ
ƒ
ƒ
ƒ
ƒ
ƒ
ƒ

levee
dam
stream/river (perennial)
canal, ditch or aqueduct (perennial)
pier/dock
runway/taxiway
pipeline (above ground)
powerline (above ground, high-tension)
aerial tramway/ski lift
natural topographic features
cliff/escarpment
perennial shoreline
railroad features (main)
carline, streetcar track, monorail, other mass transit rail
interstate highway or primary road with limited access
primary road without limited access, US highway, state highway or county
highway, secondary and connecting roads
local neighborhood road, rural road, city street
service drive (usually along a limited access highway)
alley
fencelines

Natural topographic features include the crests of well-defined mountain ridges; the rims
or bases of sharply defined escarpments, cliffs, or bluffs; the position of dry ravines or
arroyos; as well as other features as long as the features are not also mimicked by another
visible feature, have no housing in the vicinity, and are easily located on the ground.

9

Data user and Census Bureau experience has shown that some features make better
boundaries than others, and the same type of feature can make an excellent boundary in
one place and a poor one in another. Rivers, major canals, lakes, and other bodies of
water often make good statistical area boundaries because they generally limit access
from one area to another and rarely change relative location. Other features that limit
access between areas, such as interstate and other major highways, railroad tracks, and
the ridges of mountain ranges, also make good statistical area boundaries. In some
instances, however, such a feature unifies a community, for example, a lake forming the
core of a recreational housing development or a through street forming the spine of a
subdivision. In these circumstances, the statistical area boundary should include the
entire area of the lake or both sides of a unifying street to better encompass similar
community patterns.
In general, when delineating boundaries in bodies of water represented as polygons and
having area (lakes, reservoirs, bays, oceans, and wide rivers), the boundary should follow
a line bisecting the water body rather than following a shoreline. If possible, use an
existing line in water (for example, a city limit in the middle of a river) rather than adding
a new line.
Officials delineating ANVSAs may only add non-visible lines as a boundary if other
acceptable boundary features such as roads, rivers, streams, shorelines, trails and
ridgelines are not available and they aid in an ANVSA meeting other specified
delineation criteria and/or guidelines.
2.5.2 Boundary Feature Updates
The Census Bureau has spent the last six years enhancing the spatial accuracy of the
roads in our database system. The local files used during this project were required to
have an overall average accuracy of 7.6 meters while some files had better accuracy.
Although much of the street network is vastly improved, as you work with our maps you
may notice that in some counties the street and boundary features look distorted. A line
that should be straight may have a noticeable kink or pointed shape. The Census Bureau
is working to correct these problems. If you can not correctly delineate the boundary for
an entity you are updating because the feature you need to follow is incorrectly located,
mislabeled or distorted in the Census Bureau’s file, we request that you fix that feature.
In addition, we request that you report the problem area to the Seattle RCC by sending
information describing the incorrect feature and the specific entity boundary affected.
What is critical for the success of the 2010 Census data tabulation is the location of roads
relative to the tabulation entity boundary such as a city, county or ANVSA. As long as
the road is within the correct entity, the population and housing will be properly reported.
If roads are missing from our map, we ask that you add each missing road and provide
the name of the road on your ANVSA map.
2.6 Feature Extension Criteria

10

If you want to use an existing feature that doesn’t form a closed polygon, you may add a
short line to connect the features and close the polygon. The Census Bureau refers to
these lines as feature extensions and several requirements pertain. To avoid creating
ambiguous Census block boundaries, we require that feature extensions:
ƒ Are no longer than 300 feet;
ƒ Are straight lines from the end of a road and intersecting a non-road feature
(These include all hydrographic features, pipelines, powerlines, and railroads.);
ƒ Do not intersect a cul-de-sac.

3. Criteria
Participants defining American Indian and Alaska Native areas must follow a standard set
of criteria that support a shared purpose of providing a meaningful and relevant
geographic framework for tabulating data for the Census. It is the responsibility of the
Census Bureau to ensure that geographic entity criteria can achieve this goal and that the
final criteria for geographic entities are met. While aware that there are secondary uses
of geographic entities and the data tabulated for them, the Census Bureau will not modify
their boundaries or attributes specifically to meet these secondary uses, including those of
other government agencies. If a change is made to a geographic entity to meet one
specific purpose, it may be detrimental for other programs that also use these entities.
The Census Bureau will use the following criteria and guidelines to help ensure that the
ANVSAs delineated for the 2010 Census support the intended purpose of the program,
provide useful and meaningful data for the village they represent, and enhance the ability
for data users to make more meaningful comparisons between data.
Criteria are those rules and conditions that must be met when defining an ANVSA entity;
guidelines are procedures and measures suggested by the Census Bureau to enhance the
utility of ANVSAs for presentation and analysis of statistical data.
3.1 All Alaska Native Village statistical areas must follow these criteria:
1. ANVSAs delineated for the 2010 Census shall not overlap.
2. An ANVSA shall not completely surround the location of another ANV.
3. All portions of an ANVSA must be located within fifty miles of the ANV’s point
location.
4. An ANVSA shall not include more water area than land area. Large expanses of
water area should be included only to maintain contiguity, to provide a generalized
version of the shoreline, or if the water area is completely surrounded by land area
included in the ANVSA.
5. The name for an ANV must match the name corresponding to the ANV point location
in Appendix A. Name changes will only be considered if submitted in writing and
signed by the highest elected official of the ANV.
3.2 All Alaska Native Village statistical areas should follow these guidelines:
1. The population within an ANVSA should be majority Alaska Native and of that
population, the majority should be members of the population served by the
11

2. ANVSAs should be located in areas of historical and traditional significance and
include land that is locally recognized as being associated with the village or group.
In addition each ANVSA should include land area that contains structures such as
tribal headquarters, meeting areas, cultural or spiritual landmarks, service centers
and/or tribally owned stores.
3. An ANVSA should not extend beyond the regional boundary of the ANRC in which
the ANV is located.
4. An ANVSA should not exceed 325 square miles in area. Based on review of
ANVSA boundaries from previous censuses as well as other information about ANVs
and ANVSAs, the Census Bureau suggests this size as sufficient to encompass the
Alaska Native population and housing associated with each respective ANV, but not
so extensive that large amounts of non-Native population and housing are included.
5. An ANVSA should not contain large areas without housing or population.
Specifically, an ANVSA should have a housing unit density of at least three housing
units per square mile.
6. An ANVSA should be contiguous; that is, an ANVSA should form a single area with
all territory located within a continuous boundary. This makes identification of the
extent of the ANVSA easier for residents and data users, and also provides for a
clearer representation of the ANVSA’s boundaries on maps. An ANVSA, however,
may be defined with multiple noncontiguous pieces if doing so helps avoid inclusion
of population and housing not associated with the ANV.
7. An ANVSA’s boundary shall follow visible, physical features, such as rivers,
streams, shorelines, roads, trails, and ridgelines.
8. Officials delineating ANVSAs may use nonvisible lines as an ANVSA boundary only
if acceptable boundary features are not available. For example, an ANVSA boundary
may follow the nonvisible, legally defined boundaries of ANRCs, boroughs, or cities
(See section 2.5.1).
9. If the ANVSA boundary follows a governmental unit boundary, the Census Bureau
will adjust the ANVSA boundary to continue to follow that boundary should it
change due to correction, annexation or detachment.
10. When visible features listed in section 2.5.1 are not available for selection as an
ANVSA boundary, the Census Bureau, at its discretion, may approve other
nonstandard and potentially nonvisible features such as the boundaries of local and
state parks and forests, cemeteries other special land-use properties and short straightline extensions of visible features or other lines-of-sight.

4. Procedures
4.1 Annotation of Maps
4.1.1 Suggested procedures for reviewing and revising an existing ANVSA:
1. Compare your source materials with the Census Bureau’s maps.
2. If you are satisfied with how the ANVSA boundary is currently portrayed on the
Census Bureau’s maps, fill out and sign the form attached to the cover letter that
came with your materials indicating there is “no change” to the boundary. Return the
form to the RCC using the postage paid envelope provided.
3. If you need to change the ANVSA boundary, cross out the old boundary with an “X”
using a pencil with red lead. Mark the ends of the deletion with red hatch marks (//).
4. Using a pencil with purple lead, plot the revised boundaries on the Census Bureau’s
map.
5. If you must add a road or other feature, please use a black pencil to add and label this
feature. If the feature is also an ANVSA boundary, then use the red lead pencil to
highlight the feature as such.
6. If a feature is incorrectly located, mislabeled or distorted on the Census Bureau’s
maps so that you cannot correctly delineate your ANVSA boundary using that
feature, please draw your boundary (using the purple lead pencil) following the
problematic feature and contact the Seattle RCC to describe the location and nature
of the problem.
7. Remember to adjust your ANVSA boundary to follow the criteria described in
Section 3 as well as the acceptable features described under section 2.5.1.
8. Review the name of the 2000 ANVSA. The name must match the name
corresponding to the ANV point location in Appendix A. If the name is still
appropriate for the ANVSA, make no annotation. If the name requires revision, cross
out the old name and clearly label the new name in purple within the boundary of the
ANVSA. If there is a name change to something other than the name shown in
Appendix A, you must submit a written request signed by the highest elected official
of the ANV.
4.1.2 Suggested procedures for delineating a new ANVSA:
1. If you do not wish to delineate an ANVSA, fill out and sign the form attached to the
cover letter that came with your materials, indicating you do not wish to participate.
2. Compare your source materials with the Census Bureau’s map(s).
3. Using a pencil with red lead, plot the boundary on the Census Bureau’s map(s).
4. If a feature that is not on the census map(s) is required as the boundary of the
ANVSA, use a black lead pencil to add and label the new feature and the red pencil to
highlight the feature as an ANVSA boundary.
5. Ensure that the ANVSA boundary follows the criteria outlined in Section 3 as well as
the acceptable features described in the section 2.5.1.
6. If a feature is incorrectly located, mislabeled or distorted on the Census Bureau’s
maps so that you cannot correctly delineate your ANVSA boundary using that
13

feature, please draw your boundary (using the red lead pencil) following the
problematic feature and contact the Seattle RCC to describe the location and nature
of the problem.
7. Please label the name of your new ANVSA with red pencil within the boundary of
the ANVSA. The name should reflect the name associated with the ANV point
location found in Appendix A. If you wish to use a name that varies from the name
in Appendix A, you must submit a written request signed by the chairperson, chief or
president of the ANV.

Figure 3: This is an example of a new ANVSA delineated based on the provided ANV
point location.
4.2 Transmitting completed ANVSA submissions and Census Bureau review
Please return all maps to the Seattle RCC in the same tube/box/envelope you received it
in and be sure to use the mailing label provided.
The Seattle RCC will provide acknowledgment that it received the ANVSA revisions and
delineations. RCC geographers will review the ANVSA plans and contact the delineating
official if there are any questions or if the delineation does not comply with the program
criteria as described in this document. The Census Bureau reserves the right to modify,
create or reject any boundary or attribute as needed to meet final program criteria and
guidelines, or to maintain geographic relationships before the tabulation geography is
finalized for the 2010 Census.

14

4.3 Verification
If you return your submissions within 120 days of receiving the maps and other materials,
the Census Bureau will provide you with a new map, which you can use to verify that the
Census Bureau staff inserted the boundary of the ANVSA correctly. The verification
map will be provided in late 2009. At that time it would be possible for tribes to make
minor boundary changes to correct any differences from your submission that were not
previously discussed with you.

Appendix B – Procedures for accessing population and housing unit
data from American FactFinder
1. Starting at the U.S. Census Bureau internet homepage, click on “American FactFinder”
within the list along the left side of the screen.

28

2. On the next page, you will see another list on the left side on the screen. Hover your
mouse over “Data Sets” and then click on “Decennial Census” in the menu that pops up.

29

3. On the next screen, you will have the option of choosing between several different data
sets along with a small description of what each one contains. In this example, we will
access tribal block group data. For block group population data, you should select the
first data set listed which is “Census 2000 Summary File 1.” You may want to scroll
through the other data sets to see what other information is available for your future
reference.

30

4. To extract data, you will now select a number of parameters to identify your area of
interest. Again, in this example we will access tribal block group data, but you can also
access data for reservations, off-reservation trust lands, tracts, blocks and many other
geographic areas.

5. Finally, you will select the specific type of data within “Census 2000 Summary File 1”
that you are looking for. Remember that you may select multiple data types.

31

6. After clicking “Show Result” you will now see the data you have requested.

1. Introduction
The U.S. Census Bureau is the premier source of information about the American people
and the economy. The U.S. Constitution mandates that a census be taken every 10 years
in order to reapportion the House of Representatives. The data gathered by the decennial
census and other Census Bureau programs are used for several other purposes, including
the allocation and distribution of funds to state, local and tribal governments. Census
information shapes important policy decisions that in turn shape the nation’s social and
economic conditions. While best known for the decennial census, the Census Bureau
conducts numerous surveys and censuses that measure changing individual and
household demographics and the entire economic condition of the nation.
Census data help tribal elders and leaders understand what their communities need.
Many tribal communities use census information to attract new business and plan for
growth. In fact, many tribes and tribal organizations use census data to plan new
facilities and programs for the communities they serve.
In preparation for the 2010 Census, the U.S. Census Bureau has developed the Tribal
Statistical Areas Program (TSAP) to collect updates to the inventory and boundaries of
American Indian and Alaska Native statistical geographic areas. Participation in the
TSAP is voluntary. If you choose not to participate, the Census Bureau may revise the
boundary of an existing area or delineate a new area in accordance with published criteria
and guidelines. The TSAP includes the following statistical areas:
ƒ
ƒ
ƒ
ƒ
ƒ
ƒ

Alaska Native village statistical areas (ANVSAs)
Oklahoma tribal statistical areas (OTSAs) and tribal subdivisions on OTSAs
state designated tribal statistical areas (SDTSAs)
tribal designated statistical areas (TDSAs)
tribal census tracts (TCTs) and tribal block groups (TBGs) on American Indian
reservations (AIRs)/ off-reservation trust lands (ORTLs)
census designated places (CDPs)

The Census Bureau will tabulate statistical data from the 2010 Census for each entity
type listed above, and will continue to use these areas to provide data from the American
Community Survey (ACS) through the coming decade. Meaningful statistical data from
the 2010 Census and ACS provide tribes and other data users with a tool to help them
make informed decisions and plan for community services. More information about the
background and components of these geographic areas can be found in the Federal
Register notice Vol. 73, No. 221 / Friday, November 14, 2008, page 67470. This notice
can also be accessed from our TSAP webpage at
http://www.census.gov/geo/www/tsap2010/tsap2010.html.
These guidelines explain the criteria and complete instructions for delineating SDTSAs
using paper maps. The subjects covered are:

Those state liaisons wishing to delineate SDTSAs for eligible tribes in their states will
have the option of using paper maps or Census Bureau-provided Geographic Information
System (GIS) data, tools, shapefiles, and ESRI® ArcGIS® extension specific to this
program. Participants who choose to submit changes using the digital method must have
ArcGIS 9.2 or 9.3. These guidelines refer mainly to the use of paper maps.
The TSAP Extension, developed by the Census Bureau for ESRI’s ArcMap 9.2, provides
a suite of GIS data management and editing tools/commands designed for participants to
identify, delineate, and review statistical areas. Project inception, quality control, data
submission, and workflow administration are all included in the data management
features of the extension. In addition to the inherent functionality of the ArcGIS
software, the extension’s unique editing tools consist of geographic area assignment, as
well as line editing and polygon split/merge functions. The option of using either the
TSAP extension or the paper maps to submit changes is at the complete discretion of
each tribe as neither is preferred over the other by the Census Bureau. However,
depending on the number anticipated updates and/or their complexity, you might consider
using the TSAP extension which offers you the ability to view population density within
American Indian statistical areas and allow you to more clearly add or remove area or
adjust boundaries. If you are interested in using a GIS application to submit your
boundaries and you have ArcGIS 9.2 or 9.3 software, but did not receive the ArcGIS
extension software or digital data files along with your materials, please contact the
Census Bureau Regional Census Center 1 (RCC). You may also contact RCC staff to ask
other questions or arrange for training.
Disclosures to Respondents
The Geography Division manages programs to continuously update features, boundaries,
addresses, and geographic entities in the Master Address File / Topologically Integrated
Geographic Encoding and Referencing System (MAF/TIGER) database (MTdb) that is
used to support programs and to conduct the census and surveys. The TSAP program was
developed to give tribes the opportunity to review and update, if necessary, statistical
tribal entities for use in tabulating and publishing data from the 2010 Census, the
American Community Survey, and other surveys.
Public reporting burden for this collection of information is estimated to average 48 hours
per respondent, including time for reviewing instructions, assembling materials,
organizing and reviewing the information, and reporting any needed changes. We
anticipate that an estimated 650 participants will respond. Remaining entities may be

See Appendix C for RCC contact information

worked by Census Bureau regional staff. For larger areas or areas with many changes,
however, the respondent burden may be 180 hours or longer to complete. Please send
comments regarding this burden estimate or any other aspect of this collection of
information, including suggestions for reducing this burden to:

Room 3K138
Washington, D.C. 20233
You may e-mail comments to [email protected]. Use “Paperwork Project 06070795” as the subject.
Responses to this survey are voluntary. The authority for conducting these activities is
covered under the legal authority of Title 13 U.S.C. Sections 141 and 193.
No agency may conduct and no person may be required to respond to a collection of
information unless it displays a valid Office of Management and Budget (OMB) approval
number. The OMB approval number for this information collection is 0607-0795.

2. Background on SDTSAs and the TSAP
2.1 Purpose of SDTSAs
In an effort to improve the presentation of data for state recognized American Indian
tribes that did not have a reservation, boundaries for statistical areas associated with these
tribes were first introduced for the 1990 Census of Population and Housing, and then
revised during Census 2000. In Census 2000 these statistical areas were known as State
Designated American Indian Statistical Areas (SDAISAs). For the 2010 Census, they are
known as State Designated Tribal Statistical Areas (SDTSAs).
Prior to 1990, data were only tabulated for federal and state recognized reservations and
off-reservation trust lands, legal tribal subdivisions and the Historic Areas of Oklahoma
(now called OTSAs). As part of the 2010 Census, TSAP state liaisons representing state
recognized tribes will again have the opportunity to review and update the boundaries of
existing SDTSAs (SDAISAs) or delineate new SDTSAs.
SDTSAs are statistical American Indian Areas (AIAs) identified for state recognized
tribes that are not federally recognized and do not have an American Indian reservation
(AIR) or off-reservation trust lands (ORTLs). The Census Bureau works with a state
liaison appointed by each state governor to delineate these areas. SDTSAs may not cross
state lines and are limited to the state in which the respective tribe is officially
recognized. SDTSAs provide state recognized tribes without reservations statistical data
for a geographic area that encompasses a substantial concentration of tribal members.
SDTSAs are intended to provide comparable geographic entities for analyzing data over
time and to provide a way to obtain data comparable to that provided for tribes of a

similar size that have reservations or off-reservation trust lands in the same region and/or
state. The definition of a SDTSA may not necessarily include all tribal members; nor is it
intended to depict land ownership, represent an area over which a tribe has any form of
governmental authority or jurisdiction, or represent all of the traditional or historical
areas associated with the tribe, including areas used for subsistence activities.
Representation of statistical American Indian Area (AIA) boundaries in Census Bureau
products is solely for the purpose of data tabulation and presentation. Likewise,
representation of SDTSA boundaries in Census Bureau products does not convey or
confer any rights to land ownership, government authority, or jurisdictional status.
Statistical data will be tabulated for all people living within the boundaries of a SDTSA
(including non-tribe members), and also for all tribal members regardless of where they
reside in the state or nation. Each individual, whether or not he or she is located on a
tribal area, will have the same opportunity to identify their tribal affiliation. While data
tabulated for a well defined SDTSA will provide a rich source of statistical and
demographic information for the SDTSA, it is not necessary for an individual to be living
within the boundary of the SDTSA to be counted as part of a tribe. Both population and
housing unit data can be found by accessing American FactFinder on the Census
Bureau’s internet website. Directions for obtaining this data can be found in Appendix B.
2.2 Eligibility
As the TSAP state liaison appointed by your governor, you have been asked to work with
your state recognized tribes that do not have a reservation or off-reservation trust lands to
update or delineate SDTSAs. Qualifying tribes must be recognized by a formal state
recognition process. The specifics of this process vary from state to state. If for any
reason, you believe the tribe or tribes in your state should not be delineating a SDTSA
and should be delineating or updating another type of American Indian Area, please
contact your local RCC. A list of RCC contacts is available in Attachment C. If you
decline or defer participation, the Census Bureau will use 2000 SDTSA boundaries,
which will possibly be modified to reflect 2010 criteria. If no SDTSA was present in
2000, the Census Bureau will most likely not delineate one for 2010 without your
participation.
2.3 Schedule
In fall 2008, the Census Bureau mailed formal invitation letters to TSAP state liaisons for
each eligible SDTSA. These guidelines and accompanying paper maps required to
complete the work are scheduled to arrive in January 2009. State liaisons will have 120
days from the date they receive these materials to complete a review and submit their
geographic statistical area delineations or updates to the RCC. In the fall of 2009, after
the Census Bureau has reviewed and incorporated your delineations into our geographic
database, you will receive new maps or digital files so that you can verify that we have
inserted your boundaries correctly. If you have questions regarding your delineation or
submission, assistance will be available from geographers at your RCC. We strongly
encourage you to work closely with the tribes in your state throughout this process.
2.4 Program Materials

The paper map types you receive will depend on the size and mapping complexity of the
SDTSA. An SDTSA that is smaller in land area may only receive a single map sheet. A
SDTSA with a large land area may receive an index map, a series of parent maps, and a
number of inset maps. An index map shows the complete SDTSA with gridlines defining
specific areas shown on each parent map sheet. A parent map shows a detailed version of
a single grid box from the index map, and an inset map shows finer details of any areas
within the parent map where the feature network is too dense to represent clearly at the
map scale of the parent sheet. You can think of the inset map as a “blow-up” of a
specific area.

Figure 1: Example of index, parent and inset maps
If a tribe has a Census 2000 SDTSA (SDAISA) delineation, your RCC will provide a
map depicting the Census 2000 SDTSA boundary with a one-mile fringe area. If your
updates include area outside of this fringe area, please contact your RCC for maps
depicting this additional area. If a tribe did not have a Census 2000 SDTSA, your RCC
will provide county maps for the area in which the SDTSA might be delineated. If a
SDTSA should be delineated in counties for which you did not receive maps, please
contact the RCC and they will provide you with the county maps you need. Figure 2
shows entity boundaries that are shown on your maps and how they are symbolized.

Figure 2: Tribal areas symbology
The Census Bureau requests that participants use a pencil with red lead to annotate
SDTSA boundaries on the paper map provided. Procedures for annotating the maps are
detailed in section 4.
2.5 Important Information on Features
2.5.1 Acceptable Features for Use as SDTSA Boundaries
SDTSA boundaries should follow specified legal or administrative boundaries that do not
change greatly over time, or permanent, visible features, such as roads, perennial streams,
railroads, and high-tension power lines. Permanent visible features should be easily
locatable in the field by Census Bureau staff without ambiguity. The acceptable visible
boundary features are:
ƒ

levee

stream/river (perennial)
canal, ditch or aqueduct (perennial)
pier/dock
runway/taxiway
pipeline (above ground)
powerline (above ground, high-tension)
aerial tramway/ski lift
natural topographic features
cliff/escarpment
perennial shoreline
railroad features (main)
carline, streetcar track, monorail, other mass transit rail

ƒ

interstate highway or primary road with limited access
primary road without limited access, US highway, state highway or county
highway, secondary and connecting roads
local neighborhood road, rural road, city street
service drive (usually along a limited access highway)
alley
fencelines

Natural topographic features include the crests of well-defined mountain ridges; the rims
or bases of sharply defined escarpments, cliffs, or bluffs; the position of dry ravines or
arroyos; as well as other features as long as the features are not also mimicked by another
visible feature, have no housing in the vicinity, and are easily located on the ground.
Data user and Census Bureau experience has shown that some features make better
boundaries than others, and the same type of feature can make an excellent boundary in
one place and a poor one in another. Rivers, major canals, lakes, and other bodies of
water often make good statistical area boundaries because they generally limit access
from one area to another and rarely change relative location. Other features that limit
access between areas, such as interstate and other major highways, railroad tracks, and
the ridges of mountain ranges, also make good statistical area boundaries. In some
instances, however, such a feature unifies a community, for example, a lake forming the
core of a recreational housing development or a through street forming the spine of a
subdivision. In these circumstances, the statistical area boundary should include the entire
area of the lake or both sides of a unifying street to better encompass similar community
patterns.
In general, when delineating boundaries in bodies of water represented as polygons and
having area (lakes, reservoirs, bays, oceans, and wide rivers), the boundary should follow
a line bisecting the water body rather than following a shoreline. If possible, use an
existing line in water (for example, a city limit in the middle of a river) rather than adding
a new line.
Officials delineating TDSAs may only add non-visible lines as a boundary if other
acceptable boundary features such as roads, rivers, streams, shorelines, trails and
ridgelines, are not available and they aid in a TDSA meeting other specific delineations
criteria and/or guidelines. The Census Bureau staff will contact you if they require more
information or have questions about feature updates submitted as part of the 2010 TSAP.
2.5.2 Boundary Feature Updates
The Census Bureau has spent the last six years enhancing the spatial accuracy of the
roads in our database system. The local files used during this project were required to
have an overall average accuracy of 7.6 meters while some files had better accuracy.
Although much of the street network is vastly improved, as you work with our maps you
may notice that in some counties the street and boundary features look distorted. A line
that should be straight may have a noticeable kink or pointed shape. The Census Bureau

is working to correct these problems, and if you need to use a feature that is distorted in
our maps follow the guidelines below.
The Census Bureau is also now moving forward with our 2010 Census field canvassing
and collection activities. This means that we are no longer processing realignments to
our street network. What is critical for the success of the 2010 Census data tabulation is
the location of roads relative to the tabulation entity boundary. As long as the road is
within the correct entity, the population and housing will be properly reported. The
guidelines below also explain what updates are acceptable as part of the TSAP.
It is critical that participants understand that the 2010 TSAP is are not intended for street
feature updates except where a boundary follows a road (or other visible feature such as a
stream) and the road is not reflected in our file. For this reason the Census Bureau can
not accept street (or other) feature updates that do not follow the guidelines below:
2.5.3 Guidelines for Updating Features
1. If a road is missing and it forms the boundary for the area you are defining, add
the road and provide the name.
2. If you can not correctly delineate the boundary for an entity you are updating
because the feature you need to follow is incorrectly located, mislabeled or
distorted in the Census Bureau’s file, we request that you fix that feature only. In
addition, we request that you report the problem area to the Census Bureau
(through your RCC) by sending information describing the incorrect feature and
the specific entity boundary affected.
3. Do not add streets that are missing for an entire housing development (add only
streets that are needed to form a boundary). We will be adding new or missing
streets during our address canvassing operation which will occur in the spring and
early summer of 2009. The Census Bureau will provide verification materials to
each participant that returns their submission in the correct format and within the
allotted 120 days that will show the results of address canvassing. If these streets
are still missing at that time, we will accept these as adds.
2.6 Feature Extension Criteria
If you want to use an existing feature that doesn’t form a closed polygon, you may add a
short line to connect the features and close the polygon. The Census Bureau refers to
these lines as feature extensions and several requirements pertain. To avoid creating
ambiguous Census block boundaries, we require that feature extensions:
ƒ Are no longer than 300 feet;
ƒ Are straight lines from the end of a road and intersecting a non-road feature
(These include all hydrographic features, pipelines, powerlines, and railroads.);
ƒ Do not intersect a cul-de-sac.

3. Criteria
All American Indian Areas (AIAs) must follow a standard set of criteria that support a
shared purpose of providing a meaningful and relevant geographic framework for
tabulating data for the Census. It is the responsibility of the Census Bureau to ensure that
geographic entity criteria can achieve the goal of providing meaningful, relevant, and

reliable statistical data, and that the final criteria for geographic entities are met. While
aware that there are secondary uses of geographic entities and the data tabulated for them,
the Census Bureau will not modify their boundaries or attributes specifically to meet
these secondary uses, including those of other government agencies. If a change is made
to a geographic entity to meet one specific purpose, it may be detrimental for other
programs that also use these entities.
The Census Bureau will use the following criteria and guidelines to help ensure that the
SDTSAs delineated for the 2010 Census meet their definition, support the intended
purpose of the program, provide useful and meaningful data for the tribe they represent,
and enhance the ability for data users to make more meaningful comparisons between
data.
Criteria are rules that must be followed by all officials delineating statistical AIAs for the
2010 Census, while guidelines are suggestions for improving the relevance and utility of
statistical AIAs.
3.1 All State Designated Tribal Statistical Areas must follow these criteria:
1. A SDTSA must contain some American Indian population and housing.
2. A SDTSA may not overlap with any other AIA, at the same level of the geographic
hierarchy.
3. A SDTSA may not completely surround another legal or statistical AIA at the same
level of the geographic hierarchy.
4. A SDTSA may not include more water area than land area.
5. Officials delineating SDTSAs may only add nonvisible lines such as corporate limits
as a boundary if other acceptable boundary features such as roads, rivers, streams,
shorelines, trails and ridgelines, are not available and they aid in a SDTSA meeting
other specific, delineation criteria and/or guidelines.
6. The Census Bureau will evaluate the submitted name of a SDTSA to ensure that the
name is clearly distinguishable from the name of any other legal or statistical AIA.
7. SDTSAs may not include military areas.
8. An SDTSA for a specific tribe may be delineated in a state only if the tribe is
officially recognized by the state.
9. The name for each SDTSA is determined by the tribe or tribes (in conjunction with
the Census Bureau, and the state liaison for SDTSAs) that are responsible for its
delineation. The name of a SDTSA must reflect one or more of the following
conditions: The tribe that has the largest population currently residing within the
SDTSA; and/or the name of the tribe most commonly associated with the area
encompassed by the SDTSA.

3.2 All State Designated Tribal Statistical Areas should follow these guidelines:
1. SDTSAs should be comparable in area to the AIRs and/or ORTLs of other tribes with
similar numbers of members in the same state and/or region.

2. American Indians should constitute a large proportion of the population within a
SDTSA, and of the American Indian population, the majority should be members of
the delineating tribe.
3. A minimum population of at least 1,200 individuals or 480 housing units is suggested
to help enhance reliability and availability of sample-based data.
4. SDTSAs should include area where there is structured and organized tribal activity,
including tribal headquarters, tribal service centers, meeting areas and buildings,
ceremonial grounds, tribally owned commercial locations, etc.
5. SDTSAs should not contain large areas without housing or population. A housing
unit density of at least three housing units per square mile is suggested.
6. SDTSAs should be contiguous.
7. Water area should be included only to maintain contiguity, to provide a generalized
version of the shoreline, or if the water area is completely surrounded by land area
included in the SDTSA.
8. SDTSA boundaries should follow visible, physical features, such as rivers, streams,
shorelines, roads, and ridgelines.
9. SDTSA boundaries may follow the non visible, legally defined boundaries of AIRs,
ORTLs, states, counties, or incorporated places.
3.3 Things to consider when delineating SDTSAs
Since SDTSAs also will be used to tabulate and present period estimates from the ACS,
defining officials should consider that, as a general rule, period estimates of demographic
characteristics for geographic entities with small populations will be subject to higher
variances than comparable estimates for geographic entities with larger populations. In
addition, the Census Bureau’s disclosure rules may have the effect of restricting the
availability and amount of data for geographic entities with small populations. The more
closely a SDTSA’s boundary relates to the distribution of tribal members and American
Indians receiving governmental services from the tribe, and does not include large
numbers of people and households not affiliated with the tribe, the more likely that data
presented for the SDTSA will accurately reflect the characteristics of the intended tribal
population.
Although eligible, in a few cases a tribe may elect not to delineate a SDTSA if it will not
provide meaningful, relevant, or reliable statistical data because the member population
now resides in numerous other locations or has been completely subsumed by nonmember and/or non-American Indian populations. In such instances, defining a SDTSA
will not improve the presentation of statistical data relating to tribal members. These
tribes may still be able to receive meaningful, relevant, and reliable statistical data for
their tribal membership at higher levels of census geography through the characteristic of
tribal affiliation.

4. Procedures
The Census Bureau strongly encourages TSAP state liaisons to work closely with tribal
officials when delineating SDTSAs.

4.1.1 The following procedures are suggested for reviewing and revising an existing
SDTSA (SDAISA):
1. Compare your source materials with the Census Bureau’s maps.
2. If you are satisfied with how the 2000 SDTSA (SDAISA) boundary is currently
portrayed on the Census Bureau’s maps, fill out and sign the form attached to the
cover letter that came with your materials indicating there is “no change” to the
boundary. Return the form to the RCC using the postage paid envelope provided.
3. If you need to change the SDTSA boundary, cross out the old boundary with an “X”
using a pencil with red lead. Mark the ends of the deletion with red hatch marks (//).
4. Using a pencil with red lead, plot the revised boundaries on the Census Bureau’s map.
a. Please do not add street or other features unless you are adding a feature
that forms the boundary of your SDTSA. The Census Bureau will not
accept new road features at this time unless the road or other feature is
necessary in order to delineate a boundary. Please use a pencil with black
lead to add and label this feature. Then use the red lead pencil to highlight
the feature as an SDTSA boundary.
b. If a feature is incorrectly located, mislabeled or distorted on the Census
Bureau’s maps so that you cannot correctly delineate your SDTSA
boundary using that feature, please draw your boundary (using the red lead
pencil) following the problematic feature and contact your RCC to
describe the location and nature of the problem.
5. Please remember to adjust your SDTSA boundary to follow the acceptable features
described in section 2.5.
6. Review the name of the 2000 SDTSA (SDAISA). If the name is still appropriate for
the SDTSA, make no annotation. If the name requires revision, cross out the old
name and clearly label the new name in red within the boundary of the SDTSA.
Make sure the name follows the criteria described earlier. If there is a name change
for any reason, you must submit a written request signed by the chairperson, chief or
president of the SDTSA.
4.1.2 The Census Bureau suggests the following procedures for delineating a new
SDTSA:
1. If you do not wish to delineate an SDTSA for a tribe, fill out and sign the form
attached to the cover letter that came with your materials indicating you do not wish
to delineate an area.
2. Compare your source materials with the Census Bureau’s map(s).
3. Using a pencil with red lead, plot the boundary on the Census Bureau’s map(s).
4. If a feature that is not on the census map(s) is required as the boundary of the
SDTSA, use a black lead pencil to add and label the new feature and the red pencil to
highlight the feature as an SDTSA boundary.
a. Please do not add street or other features unless you are adding a feature
that forms the boundary of your SDTSA. The Census Bureau will not
accept new road features at this time unless the road or other feature is
necessary in order to delineate a boundary. Please use a pencil with black
lead to add and label this feature. Then use the red lead pencil to highlight
the feature as an SDTSA boundary.

b. If a feature is incorrectly located, mislabeled or distorted on the Census
Bureau’s maps so that you cannot correctly delineate your SDTSA
boundary using that feature, please draw your boundary (using the red lead
pencil) following the problematic feature and contact the your RCC to
describe the location and nature of the problem.
5. Ensure that the SDTSA boundary follows the acceptable features described in section
2.5.
6. Clearly label the name of the new SDTSA in red within the boundary of the SDTSA.
Examples:

Figure 1: Area is being removed from the SDTSA shown in white.

Figure 2: Area is being added to the SDTSA shown in white.
4.2 Transmitting completed submissions and Census Bureau review
Please return all maps to the RCC in the same tube/box/envelope you received it in and
be sure to use the mailing label provided.
The Census Bureau RCC geographic staff will verify that the submitted SDTSAs are
complete, meet all criteria and other requirements and, where the criteria have not been
met, a valid justification is provided. The Census Bureau will provide feedback to the
participant on their submission and if necessary provide additional guidance on the
criteria and guideline usage. The Census Bureau will contact you with any questions or
concerns regarding this submission. The Census Bureau reserves the right to modify,
create, or reject any boundary or attribute as needed to meet the final program criteria and
guidelines or to maintain geographic relationships before the tabulation geography is
finalized for the 2010 Census.
4.3 Verification
If you return your submission with 120 days of receiving the maps and other materials,
the Census Bureau will provide you with a new map, which you can use to verify that the
Census Bureau staff inserted the boundary of the SDTSA correctly. The verification map
will be provided in late 2009. At that time it would be possible for tribes to make minor
boundary changes or add features that still may be missing from our maps.

Appendix B – Procedures for accessing population and housing unit
data from American FactFinder
1. Starting at the U.S. Census Bureau internet homepage, click on “American FactFinder”
within the list along the left side of the screen.

2. On the next page, you will see another list on the left side on the screen. Hover your
mouse over “Data Sets” and then click on “Decennial Census” in the menu that pops up.

3. On the next screen, you will have the option of choosing between several different data
sets along with a small description of what each one contains. In this example, we will
access tribal block group data. For block group population data, you should select the
first data set listed which is “Census 2000 Summary File 1.” You may want to scroll
through the other data sets to see what other information is available for your future
reference.

4. To extract data, you will now select a number of parameters to identify your area of
interest. Again, in this example, we will access tribal block group data, but you can also
access data for reservations, off-reservation trust lands, tracts, blocks, and many other
geographic areas.

5. Finally, you will select the specific type of data within “Census 2000 Summary File 1”
that you are looking for. Remember that you may select multiple data types.

6. After clicking “Show Result” you will now see the data you have requested.

1. Introduction
The U.S. Census Bureau is the premier source of information about the American people
and the economy. The U.S. Constitution mandates that a census be taken every 10 years
in order to reapportion the House of Representatives. The data gathered by the decennial
census and other Census Bureau programs are used for several other purposes, including
the allocation and distribution of funds to state, local and tribal governments. Census
information shapes important policy decisions that helps shape the nation’s social and
economic conditions. While best known for the decennial census, the Census Bureau
conducts numerous surveys and censuses that measure changing individual and
household demographics and the entire economic condition of the nation.
Census data help tribal elders and leaders understand what their communities need.
Many tribal communities use census information to attract new business and plan for
growth. In fact, many tribes and tribal organizations use the census data to plan new
facilities and programs for the communities they serve.
In preparation for the 2010 Census, the U.S. Census Bureau has developed the State
Reservation Program (SRP). The SRP provides an opportunity for state officials, working
with state-recognized tribes that have a state American Indian reservation (AIR) to
review and, as needed, update the boundaries and names for American Indian
Reservations (AIRs) for state-recognized American Indian tribes. State recognized tribes
that do not have an AIR are eligible to delineate a state designated tribal statistical area
(SDTSA) as part of our Tribal Statistical Area Program (TSAP). The TSAP also
provides opportunities for federally recognized tribes to delineate other statistical areas as
appropriate. Because the Census Bureau works with a single state appointed liaison to
review and update the state recognized reservations and to delineate state designated
tribal statistical areas, TSAP and the SRP are conducted in tandem.
The Census Bureau will tabulate statistical data from the 2010 Census for state AIRs, and
all TSAP entities, and will continue to use these areas to provide data from the American
Community Survey (ACS) through the coming decade. Meaningful statistical data from
the 2010 Census and ACS provide tribes and other data users with a tool to help them
make informed decisions and plan for community services. More information about the
background and components of these geographic areas can be found in the Federal
Register notice Vol. 73, No. 221 / Friday, November 14, 2008, page 67470. This notice
can also be accessed from our TSAP webpage at:
http://www.census.gov/geo/www/tsap2010/tsap2010.html
These guidelines explain the background, criteria and complete instructions for updating
and delineating state AIRs using paper maps. The topics covered are:

Census Bureau Submission Review
Verification

Those wishing to participate in the SRP will have the option of updating or delineating
their state AIRs using paper maps or Census Bureau-provided Geographic Information
System (GIS) data, tools, shapefiles, and ESRI® extension specific to this program.
Participants who choose to submit changes using the digital method must have ArcGIS®
9.2 or 9.3. These guidelines provide instructions for the use of paper maps. There
are separate guidelines for the use of the ESRI extension which can be found on the data
disc.
The TSAP Extension, developed by the Census Bureau for ESRI’s ArcMap 9.2, provides
a suite of GIS data management and editing tools/commands designed for participants to
identify, delineate, and review statistical areas. Project inception, quality control, data
submission, and workflow administration are all included in the data management
features of the extension. In addition to the inherent functionality of the ArcGIS
software, the extension’s unique editing tools consist of geographic area assignment,
block boundary definition, tribal tract/tribal block group type attribution, as well as line
editing and polygon split/merge functions. The option of using either the TSAP
extension or the paper maps to submit changes is at the complete discretion of each tribe
as neither is preferred over the other by the Census Bureau. However, depending on the
number anticipated updates and/or their complexity, you might consider using the TSAP
extension which offers you the ability to view population density within American Indian
statistical areas and allow you to more clearly add or remove area or adjust boundaries.
If you are interested in using this GIS application to submit your boundaries and you
have ArcGIS 9.2 or 9.3 software, but did not receive the ArcGIS extension software or
digital data files along with your materials, please contact your RCC 1 . You may also
contact the RCC staff to ask other questions or to arrange for training.
Disclosures to Respondents
The Geography Division manages programs to continuously update features, boundaries,
addresses, and geographic entities in the Master Address File / Topologically Integrated
Geographic Encoding and Referencing System (MAF/TIGER) database (MTdb) that is
used to support programs and to conduct the census and surveys. The TSAP program was
developed to give tribes the opportunity to review and update, if necessary, statistical
tribal entities for use in tabulating and publishing data from the 2010 Census, the
American Community Survey, and other surveys.
Public reporting burden for this collection of information is estimated to average 48 hours
per respondent, including time for reviewing instructions, assembling materials,
organizing and reviewing the information, and reporting any needed changes. We
anticipate that an estimated 650 participants will respond. Remaining entities may be

number. The OMB approval number for this information collection is 0607-0795.

2. Background on the State Reservation Program
The 1890 Census was the first in which American Indian data were collected and
presented for individual AIRs. The Census Bureau began to report data systematically
for a variety of American Indian Areas (AIAs) starting in 1980, when it identified and
presented data for a more complete inventory of AIRs. The Census worked with the
Bureau of Indian Affairs to identify boundaries for AIRs of federally recognized tribes,
and with state government officials to identify boundaries for state recognized AIRs, by
obtaining maps depicting their legally established boundaries.
The SRP occurs once before each decennial census, and is a survey of state AIRs for
those states with state-recognized tribes that are not also federally recognized. Its purpose
is to determine, solely for data collection and tabulation by the Census Bureau, the
complete and current inventory and the correct attributes (names, legal descriptions,
official status) and official, legal boundaries of the state AIRs in each state. Through the
State Reservation Program, the Census Bureau also accepts additions and updates to
features such as roads or rivers that serve as a boundary for the state AIR, as well as
address range break information at the boundaries.
As part of the 2010 Census, state officials will again have the opportunity to review and
update the boundaries of their existing state AIRs or to provide boundaries and other
attribute information for newly recognized state AIRs. If the state AIR official declines
or defers participation, the Census Bureau will use 2000 state AIR boundaries, to tabulate
2010 Census data.
2.1 Eligibility
3

In order to delineate a state AIR for the 2010 Census the tribe associated with the AIR
first must be state recognized. While the Bureau of Indian Affairs (BIA) serves as a
single source for determining which American Indian tribes are federally recognized,
state recognition varies by state. Some states have unique laws that recognize specific
tribes while other states have established a formal process by which tribes apply for state
recognition. State AIRs and their legal boundaries are established pursuant to state law.
Prior to the decennial census and before implementing the state reservation program, the
Census Bureau sends a letter to the governor of each state requesting a list of any staterecognized tribes that are not also federally recognized, and requesting appointment of a
liaison to work with the state recognized tribes and the Census Bureau on geographic
programs. State recognition of a tribe is determined by each respective state government
and conveyed to the Census Bureau by the governor’s appointed liaison. The Census
Bureau will work with the state’s liaison to ascertain a tribe’s status if contacted directly
by a tribe who is claiming state recognition but has not been included on the state’s list of
recognized tribes.
As the liaison for both the SRP and the TSAP, the Census Bureau will work with you to
determine which tribes are eligible for delineating a SDTSA. The list of eligible staterecognized tribes for each individual state will change if new tribes are recognized and
reported to the Census Bureau by that state’s liaison on or before January 1, 2010. The
current list is provided in Appendix A.
2.2 Schedule
In October 2008, the Census Bureau mailed formal invitation letters to state liaisons.
These guidelines and accompanying paper maps required to complete the work are
scheduled to arrive in January 2009. The state liaison will have 120 days from the date
they receive SRP materials to complete a review and submit state AIR delineations or
updates to the RCC. In late 2009, after the Census Bureau has reviewed and incorporated
your delineations into our geographic database, you will receive new maps or digital files
so that you can verify that we have inserted your boundaries correctly. If you have
questions regarding your delineation or submission, assistance will be available from
geographers at your RCC. The Census Bureau strongly encourages you to work with
tribal officials throughout this process.
2.3 Program Materials
If a state has a Census 2000 state AIR(s), the Census Bureau’s RCC will provide maps
depicting the Census 2000 boundary for each state AIR within a one-mile fringe area. If
your updates include area outside of the fringe area, please contact your RCC for
additional maps. If one or more of your state recognized tribes did not have a state AIR
delineated for 2000, but they do have a legally defined reservation that you want to
provide boundaries for 2010, the RCC will work with you to provide map coverage.
County-based maps will be used for this purpose.
The paper map types you receive will depend on the size and mapping complexity of
your state AIR. A state AIR that is smaller in land area may only receive a parent map
4

sheet. State AIRs with large land area may receive an index map, a series of parent maps,
and a number of inset maps. An index map shows the complete state AIR with gridlines
defining specific areas shown on each parent map. A parent map shows a detailed
version of a single grid box from the index map, and an inset map shows finer details of
any areas within the parent map where the feature network is too dense to represent
clearly at the map scale of the parent sheet. You can think of the inset map as a “blowup” of a specific area.

Figure 1: Example of index, parent and inset maps

Figure 2: Tribal areas symbology on maps
The Census Bureau requests that participants use a pencil with red lead to annotate state
AIR boundaries on the paper maps provided. Procedures for annotating the paper maps
are detailed in section 4.
2.4 Boundary Feature Updates

5

The Census Bureau has spent the last six years enhancing the spatial accuracy of the
roads in our database system. The local files used during this project were required to
have an overall average accuracy of 7.6 meters with some files having better accuracy.
Although much of the street network is vastly improved, as you work with our maps you
may notice that in some counties the street and boundary features look distorted. A line
that should be straight may have a noticeable kink or pointed shape. The Census Bureau
is working to correct these problems, and if you need to use a feature that is distorted in
our maps follow the guidelines below.
The Census Bureau is also now moving forward with our 2010 Census field canvassing
and collection activities. This means that we are no longer processing realignments to
our street network. What is critical for the success of the 2010 Census data tabulation is
the location of roads relative to the tabulation entity boundary. As long as the road is
within the correct entity, the population and housing will be properly reported. The
guidelines below explain what updates are acceptable as part of the SRP.
It is critical that participants understand that the SRP is not intended for street feature
updates except where a boundary follows a road (or other visible feature such as a
stream) and the road is not reflected in our file. For this reason the Census Bureau can
not accept street (or other) feature updates that do not follow the guidelines below:
2.4.1 Guidelines for Updating Features
1. If a road is missing and it forms the boundary for the area you are defining, add
the road and provide the name.
2. If you can not correctly delineate the boundary for an entity you are updating
because the feature you need to follow is incorrectly located, mislabeled or
distorted in the Census Bureau’s file, we request that you fix that feature only. In
addition, we request that you report the problem area to the Census Bureau
(through your RCC).
3. Do not add streets that are missing for an entire housing development (add only
streets that are needed to form a boundary). We will be adding new or missing
streets during our address canvassing operation which will occur in the spring and
early summer of 2009. The Census Bureau will provide verification materials to
each participant that returns their submission in the correct format and within the
allotted 120 days that will show the results of address canvassing. If these streets
are still missing at that time, we will accept these as adds.

3. Criteria
State AIR boundaries and names should be reported to the Census Bureau as they exist in
the legislation or treaty under which they were established. By definition, state AIR
boundaries cannot cross state lines unless the AIR and tribe is separately recognized in
each state. State AIRs may not include territory within federally recognized AIRs or off
reservation trust lands. Acceptance of boundary changes to state AIRs requires clear
legal documentation supporting any, and all, changes involving these boundaries. The
Census Bureau will identify each state AIR with the name submitted by the state liaison

6

providing the boundary for the area. For this reason, the state AIR name should reflect
the specific tribal name cited in the legal records establishing the state AIR.

4. Procedures
4.1 Annotating Maps
The Census Bureau strongly encourages SRP state liaisons to work closely with tribal
officials to review state AIRs.
4.1.1 Suggested procedures for reviewing and revising an existing state AIR:
1. Compare your source materials with the Census Bureau’s maps.
2. If you are satisfied with how the state AIR boundary is currently portrayed on the
Census Bureau’s maps, fill out and sign the form attached to the cover letter that
came with your materials indicating there is “no change” to the boundary. Return the
form to the RCC using the postage paid envelope provided.
3. If you need to change the state AIR boundary, cross out the old boundary with an “X”
using a pencil with red lead. Mark the ends of the deletion with red hatch marks (//).
4. Using a pencil with red lead, plot the revised boundaries on the Census Bureau’s map.
a. Please do not add street or other features unless you are adding a feature
that forms the boundary of your state AIR. The Census Bureau will not
accept new road features at this time unless the road or other feature is
necessary in order to delineate a boundary. Please use a pencil with black
lead to add and label this feature. Then use the red lead pencil to highlight
the feature as a state AIR boundary.
b. If a feature is incorrectly located, mislabeled or distorted on the Census
Bureau’s maps so that you cannot correctly delineate your state AIR
boundary using that feature, please draw your boundary (using the red lead
pencil) following the problematic feature and contact your RCC to
describe the location and nature of the problem.
5. On the paper map, “delete” any incorrect boundaries by drawing “X”s along the
boundary using the appropriate colored pencil.
6. Review the name of the 2000 state AIR. If the name is still appropriate for the state
AIR, make no annotation. If the name requires revision, cross out the old name and
clearly label the new name in red within the boundary of the state AIR.
4.1.2 Suggested procedures for delineating a new state AIR:
1. Compare your source materials with the Census Bureau’s map(s).
2. Using a pencil with red lead, plot the boundary on the Census Bureau’s map(s).
3. If a feature that is not on the census map(s) is required as the boundary of the state
AIR, use a black lead pencil to add and label the new feature and the red pencil to
highlight the feature as a state AIR boundary.
a. Please do not add street or other features unless you are adding a feature
that forms the boundary of your state AIR. The Census Bureau will not
accept new road features at this time unless the road or other feature is
7

necessary in order to delineate a boundary. Please use a pencil with black
lead to add and label this feature. Then use the red lead pencil to highlight
the feature as a state AIR boundary.
b. If a feature is incorrectly located, mislabeled or distorted on the Census
Bureau’s maps so that you cannot correctly delineate your state AIR
boundary using that feature, please draw your boundary (using the red lead
pencil) following the problematic feature and contact your RCC to
describe the location and nature of the problem.
4. Clearly label the name of the new State AIR in red within the boundary of the AIR.

Figure 3: In this example, area is being added to an existing State AIR.

8

Figure 4: In this example, area is being removed from the State AIR.
Acceptance of state AIR boundary changes to state AIRs requires clear legal
documentation supporting any and all changes involving these boundaries.
4.2 Transmitting completed submissions and Census Bureau review
Please return all maps and copies of relevant documentation describing the State AIR
boundary location in the same tube/box/envelope you received it in and be sure to use the
mailing label provided. The Census Bureau RCC geographic staff will verify that the
submitted state AIRs are complete, and that all legal documentation is provided. The
Census Bureau will contact you with any questions or concerns regarding your
submission.
4.3 Verification
If you return your submission within 120 days of receiving the maps and other materials,
the Census Bureau will provide you with a new map, which you can use to verify that the
Census Bureau staff inserted the boundary of the State AIR correctly. The verification
map will be provided in late 2009. At that time it would be possible for tribes to make
minor boundary corrections if necessary.

Appendix B – Procedures for accessing population and housing unit
data from American FactFinder
1. Starting at the U.S. Census Bureau internet homepage, click on “American FactFinder”
within the list along the left side of the screen.

2. On the next page, you will see another list on the left side on the screen. Hover your
mouse over “Data Sets” and then click on “Decennial Census” in the menu that pops up.

2

3. On the next screen, you will have the option of choosing between several different data
sets along with a small description of what each one contains. In this example, we will
access tribal block group data. For block group population data, you should select the
first data set listed which is “Census 2000 Summary File 1.” You may want to scroll
through the other data sets to see what other information is available for your future
reference.

3

4. To extract data, you will now select a number of parameters to identify your area of
interest. Again, in this example we will access tribal block group data, but you can also
access data for reservations, off-reservation trust lands, tracts, blocks, an many other
geographic areas.

4

5. Finally, you will select the specific type of data within “Census 2000 Summary File 1”
that you are looking for. Remember that you may select multiple data types.

6. After clicking “Show Result” you will now see the data you have requested.
