1.0 Overview of the BAS
The Census Bureau conducts the Boundary and Annexation Survey (BAS) annually to
collect and maintain the most current, legally established boundary information for
federally recognized American Indian reservations, off-reservation trust land and tribal
subdivisions. In support of the government-to-government relationship with federally
recognized American Indian tribes, the Census Bureau works directly with tribal officials
to maintain a current and comprehensive inventory of correct names, legal descriptions
and legal boundaries for federally recognized tribes with reservations and/or offreservation trust lands.
The Census Bureau’s primary purpose for delineating tribal boundaries is to develop the
best possible geographic framework for the tabulation and presentation of statistical
information. Through the BAS, the Census Bureau updates reservation, off-reservation
trust land and tribal subdivision boundaries, as well as their names and features (features
such as roads or rivers), and address information at the boundaries. The information
collected is used to tabulate data from various programs and surveys, such as the
American Community Survey and 2010 Census. Maintaining these boundaries and
boundary-to-feature relationships correctly through the BAS makes certain that the
appropriate population is assigned to your area.
To complete the BAS, please review the maps in your BAS package. If the boundary of
your American Indian Area (AIA) is correct, please submit the “No Change” postcard. If
there are changes to your contact information, the Census Bureau appreciates your
cooperation in updating the BAS forms, included in your package. You can access the
electronic version of the form at the following website:
, click on “Response Methods”.
Make changes on the maps and return the updated maps, appropriate legal documentation
and forms to the Census Bureau by March 1.
If a tribal government disagrees with the Census Bureau’s depiction of their boundary
and provides supporting documents that pre-date 1990, when our boundaries were last
sanctioned by the BIA, we ask for clarification from the U.S. Department of the Interior,
Office of the Solicitor regarding the correct current boundary. Complicated legal land
issues often require an extended period of time for resolution, and in those cases, the
Census Bureau retains the boundary we have in our database until a legal opinion is
issued by the Solicitor’s office.

In compliance with the Office of Management and Budget Circular A-16, the BAS
supports the Census Bureau’s spatial data steward responsibilities for the Federal
Geographic Data Committee and the Geospatial One-Stop by updating the inventory
of and boundaries for governmental units. In addition, the BAS is the source of upto-date information on boundaries, codes, and names for the U.S. Geological
Survey’s (USGS) National Map and the Geographic Names Information System.

2.0 Updating the BAS Materials
There are six steps involved in updating the BAS materials:
•
•
•
•
•
•

Reviewing and updating (if necessary) the geographic information on the BAS-5
form
Reviewing and annotating the map(s) with boundary changes and corrections
Annotating feature changes, additions, or deletions on the map
Annotating the address breaks at the intersection of roads and boundaries
Signing the updated maps and forms
Returning the signed maps and forms along with legal documentation supporting
all legal boundary changes (for example, additions and deletions of trust land)

It is important that all questions on the form are answered completely. If there are no
changes to report, please return only the “No Change” postcard provided with your
materials. Please do not return all of the materials. If there are changes, sign and return
only the maps with changes. (You can access the electronic version of the form at the
following website: ). Return
the completed form(s) and updated map(s) using the pre-addressed envelope or return
label by March 1 to:
National Processing Center
ATTN: BAS Returns, Bldg 63A
1201 East 10th Street
Jeffersonville, IN 47132
2.1 Reviewing and Updating Your Form
Begin with a review of all information printed on your form. If any information needs to
be changed, cross out the incorrect data and print the correction beside it. Provide an
effective date for name, type or status changes. Regarding misspelled names, cross out
the error and print the correctly spelled name next to the misspelling.

To change the name of a federally recognized American Indian reservation, offreservation trust land or tribal subdivision, follow the directions as shown in Example 2.1
below:
•
•
•
•

Mark the “No” box
Print the correct name and effective date of the change in the box provided
Provide documentation, such as a tribal resolution or Federal Register Notice to
support the change
Continue with question 2

Example 2.1: Updating the tribal BAS-5 form and Question 1.

2.2 Making Changes and Corrections to Your Maps
This section includes general guidelines and detailed examples illustrating how to update
boundary and feature information.
Maps Included in BAS Packages
In the past, the Census Bureau mailed an index map and all parent sheets to each entity
with 40 or fewer total map sheets. Entities with more than 40 map sheets received only
an index map. In 2008, we established a new process that determines which map sheets
contain any portion of the subject entity’s boundary. These map sheets form the
“boundary ring” and are determined for any entity with more than 40 map sheets.
Entities with over 40 total map sheets, but less than 40 boundary ring sheets now receive
their index sheet and boundary ring. Map sheets for the interior of the entity are
excluded. This allows entities that previously would have only received an index sheet to
receive the additional map sheets containing their boundary. If an entity has over 40
boundary ring map sheets, then the participant will receive a standard index sheet only.
A maximum of 40 map sheets will be sent to a participant. Full sets of maps can be
requested as needed.

There are a number of general guidelines for changes and corrections to your maps:
•

Three colored pencils are provided in your package: The red pencil should be
used to indicate legal boundary changes or corrections. Use the purple pencil to

Tribal Boundary and Annexation Survey Respondent’s Guide

3

indicate non-legal changes or corrections. Use the blue pencil to add or modify
tribal subdivisions.
•

Compare the BAS maps to a local source for your entity. Update the map(s) if the
boundary shown does not correctly depict your boundary as of January 1 of the
survey year.

•

Refer to examples 2.2.2 through 2.2.5 for the differences between a boundary
change and a boundary correction.

•

Updating Address Information
The BAS maps show the last address stored in our geographic database for each
street that crosses the boundary of your reservation. These addresses are shown
because it is important that the Census Bureau assigns the correct addresses to
each governmental unit. If you have reported an addition or deletion, or have
corrected our depiction of your boundary and you have house numbers, street
names, and addresses, please provide us with the last address within the current
boundary of your reservation.
Since the BAS only collects addresses at the boundary, the Census Bureau has
other programs that determine address information. If you have a reliable source
for addresses within your reservation, and would be willing to share that
information with the Census Bureau, we request that you fill out the Address
Source Information Worksheet included on the last page of this guide. The
Census Bureau staff working on the BAS responses will forward the updated form
to the address update staff with the information you provide. The correct
assignment of addresses is of primary importance to our censuses and surveys.

•

Although the BAS collects boundary information, the survey also accepts feature
updates. You should not, however, attempt to correct the spatial accuracy of
streets on the BAS maps; correct only those streets that are significantly mislocated, or new streets that are related to the location of a new boundary. Please
refer to examples 2.2.7 through 2.2.16, and be sure to use the enclosed purple
pencil for feature updates.

•

Please do not make changes on the index map. Index maps are provided as a
reference to help you quickly locate a map sheet. If you received only an index
map for your reservation or trust land and you need to make boundary changes
and/or feature updates, please call the phone number indicated on the BAS-5 form
or e-mail [email protected] to request a full set of maps or the specific map
sheet(s) needed.

In Example 2.2.1, Cheyenne River Reservation1 is the subject area. Off-reservation trust
lands (T0605) are represented by a brown dot pattern. Note that all areas outside of the
subject area are considered fringe areas. Fringe areas are shaded with a gray dot pattern.
(Ziebach 137 and Haakon 055 are counties.)

Example 2.2.1: Reservation with tribal subdivision, county boundary, and trust land

2.2.2 Boundary changes versus boundary corrections
The two types of modifications that can be made to a boundary are: boundary changes
and boundary corrections.
•

•

A boundary change is a legal change to a boundary as a result of a federal court
decision, treaty, act of Congress, a deed placing land in trust, etc. Copies of the
legal documentation must be submitted with all boundary changes. Reporting
legal boundary changes is the primary goal of the BAS.
A boundary correction is the minor adjustment of a boundary to correct a drafting
error in the Census Bureau’s depiction of an existing boundary and does not
require documentation.

2.2.3 Boundary changes
These figures illustrate how to correctly draw boundary changes on your maps and to
update the BAS form. Using the red pencil provided, cross out the portion of the
boundary that is no longer current with a string of “X”’s as shown in example 2.2.4.3.
Draw the new boundary line(s) ensuring that you close your boundary and do not leave
an incomplete boundary as shown in example 2.2.3.1. Add the authorization number or
other identifier of the action authorizing the change, along with the effective date of each
addition or deletion that you draw on the map. Document these changes on the BAS
form as shown below.

Note that all examples are for graphical purposes only and do not represent actual boundary, feature or
address changes. The baseline geography for most figures is from the Cheyenne River Reservation.

Tribal Boundary and Annexation Survey Respondent’s Guide

Note that if you are adding a trust land, please annotate as shown in example 2.2.3.1,
where the original reservation boundary is not deleted and so does not need the string of
“X”’s.
Complete Boundary

Incomplete Boundary

Example 2.2.3.1: The first figure illustrates how to make a complete boundary change. The second figure
illustrates a common error with an incomplete boundary change.

Example 2.2.3.2: Updating boundary changes on the tribal BAS form, BAS-5

2.2.4 Boundary with coincident feature change
Example 2.2.4.1 illustrates how to make an adjustment to a boundary that is coincident
with a feature, such as a river or street. In this case, the feature location is correct, but
the boundary location is incorrect. Using the red pencil, you will cross out the portion of
the boundary that is no longer current using a string of “Xs” inside circles. Draw the
updated boundary. Add the authorization number or other identifier of the action
authorizing the change along with the effective date of each addition or deletion.
Document these changes on the tribal BAS form as shown in the following figures.
If you want to move both the boundary and the feature, cross out the incorrect boundary
with a string of red “Xs” and draw a red line representing the new location of the
boundary and road. Example 2.2.4.3 illustrates how to make a correction to the boundary
Tribal Boundary and Annexation Survey Respondent’s Guide

where an associated feature moves along with the boundary. If these changes are the
result of an annexation or deannexation, include the authorization number and effective
date.

Example 2.2.4.1: Making a change to a boundary coincident with a road feature, where only the boundary
moves to the new location

Example 2.2.4.2: Updating the tribal BAS form for a change to a boundary coincident with a feature

Example 2.2.4.3: Making a change to a boundary coincident with a road feature, where both the boundary
and feature move to the new location

2.2.5 Boundary corrections
A boundary correction usually corrects a minor drafting error and does not significantly
change the shape of the boundary. Boundary corrections do not require documentation,
but we may need to contact you for clarification.
This figure illustrates how to complete a boundary correction on the map and tribal BAS
form. Using the enclosed red pencil provided, cross out the incorrect boundaries with a
string of “Xs”, add a line showing the correct boundary and print the letters “BC” as
shown in the figure below, to identify the change as a boundary correction rather than a
legal change.

Example 2.2.5.1: Making a boundary correction

2.2.6 Tribal subdivision program procedures
Tribes may submit the boundaries for one type of administrative area within their
reservation(s) and/or off-reservation trust land for inclusion into the Census Bureau’s
geographic database. The Census Bureau will consider any type of unit of selfgovernment or administration as a “tribal subdivision.” If submitted, tribal subdivisions
should cover all or most, of the tribe’s reservation or off-reservation trust land.
Tribes that delineated tribal subdivisions during earlier BAS cycles may review and
correct names, type and status of subdivisions in the Tribal Names and Status
Documentation section of the BAS-5 form (see the last two pages of your BAS-5 form).
Additionally, tribes should review the information shown on the maps and note any
needed change or correction to their tribal subdivision’s boundaries.
The tribe may submit only one type of subdivision, even if it has more than one type of
distinct administrative area that could qualify as a tribal subdivision (e.g., tribal election
districts, tribal water districts, or health service areas with different boundaries). Tribal
subdivisions can be considered either active (A) or inactive (I). Active subdivisions are
defined as having a functioning government, with elected officials, that provides
programs and services. Inactive subdivisions have no functioning government or elected
officials and receive services solely from the tribe.

Tribal Boundary and Annexation Survey Respondent’s Guide

You will have an opportunity to delineate unincorporated population centers (Census
Designated Places) within your reservation during the upcoming 2010 Decennial Tribal
Statistical Area Programs (TSAP). These should not be delineated as tribal subdivisions.
Some examples of areas submitted as tribal subdivisions are:
•

Areas used by your tribe for the election of tribal government officials (e.g.,
districts or precincts used for the election of tribal council members)

•

Areas used by your tribal government for tax purposes

•

Areas used by your tribal government for the provision of general services or
specified services, such as:
o
o
o
o

water districts
health service areas
emergency service delivery areas (e.g., 911, fire, and/or police), or
grazing districts or range units

•

Historical or traditional areas recognized by your tribal government

•

Sub-reservation tribal community governments

The Census Bureau requests that you add and/or revise your tribal subdivision boundaries
on the BAS map(s) and complete the forms enclosed within this package. (If a full set of
BAS maps has not been sent, please request them by calling your Regional Census
Center.2) If your tribe delineated tribal subdivisions during a prior survey, tribal
subdivision boundaries are symbolized on the enclosed BAS maps by a solid blue line.
Before you add/or revise your tribal subdivision boundaries on the enclosed map(s),
please note any changes to the boundary of your land base on the map(s) using the
enclosed red pencil. Add and/or revise the boundaries of your tribal subdivisions on the
enclosed BAS map(s) using the enclosed blue pencil. Additionally, the names and type
(active or inactive) of your subdivisions are listed in the Tribal Names and Status
Documentation section of the BAS-5 form. Please review and update this information.
If this is the first time you are providing tribal subdivisions, please add the boundaries on
the BAS map(s) using the enclosed blue pencil. You must label each tribal subdivision
on each map sheet with its name (e.g., “District 3,” “Arlee District,” “White Rock
Chapter,” “Parmelee Community,” and so forth) and record the names, type, and status of
each in the Tribal Names and Status Documentation section of the BAS-5 form.
Examples of the tribal subdivisions include, but are not limited to: chapters,
communities, districts, segments, and villages. If a tribal subdivision boundary follows a
visible feature such as a stream, road, or fence line, please be sure to indicate that on BAS
map. Add the visible feature it follows if it is not already shown.

If you have any questions, please contact your Census Bureau Regional Office’s
Geography staff at the telephone number shown on your enclosed BAS-5 form.
The following is a list of the criteria for defining tribal subdivisions:
• Tribal subdivisions should cover all, or most, of the tribe’s land base.
• The delineation of tribal subdivisions is restricted to the area contained within
your reservation(s) and/or associated off-reservation trust lands.
• There is no minimum population threshold for a tribal subdivision.
• A tribal subdivision may be discontiguous.
• Your tribe may designate only ONE type of tribal subdivision. If your tribe has
more than one level of tribal subdivisions within its land base, the Census Bureau
recommends delineating subdivisions corresponding to the lowest geographic
level (i.e., those geographic areas containing the smallest area) of the tribe’s
administrative hierarchy.
• Tribal subdivisions should not be based solely on land ownership or other
cadastral areas, nor should they consist of divisions based on the U.S. public land
survey system of townships, ranges, and sections, if these areas have no
governmental or administrative function for your tribe.
If you have any questions or need to request additional maps, please contact your
Regional Office’s Geography staff at the telephone number shown on your enclosed
BAS-5 form.

Example 2.2.6.1: Depicting a tribal subdivision

2.2.7 Feature modifications
This figure illustrates how to make feature modifications that may or may not be
coincident with a boundary. Using the purple pencil, you will cross out the incorrect
feature location with “Xs”. Draw the feature in the correct location, and print the name
of the feature as shown in the figure below.

Example 2.2.7: Making a feature modification to a road that does not move the locations of the boundary.

If the feature was previously coincident with a boundary, this modification will not affect
the location of the boundary. If you wish to move both the boundary and the feature,
please refer to section 2.2.4.
Note that adding features internal to the boundary of your reservation or off-reservation
trust land is not required as part of the BAS. This is also true for other features such as
streams, point features or areal features.
2.2.8 Edits to street information
This figure illustrates how to add missing streets, new streets and alternate street names.
•
•

When adding a missing street, new street, or other feature on the map, use the
purple pencil to draw the feature and its name on the map, as shown in the figure
below. “(Cty 5)” is the alternate name for “Willow Street”.
If you know an alternate street name, print the alternate in parentheses as shown
in the following figure.

Example 2.2.8: Adding a road feature with annotation and an alternate road name

Tribal Boundary and Annexation Survey Respondent’s Guide

12

2.2.9 Adding feature names in a congested area
This figure illustrates how to add feature names to a congested area on the map. Using
the purple pencil, draw the features onto the map. If the area is too congested to add all
feature names on the map provided, number each feature and list this number and the
corresponding feature name in the map margin or an uncongested spot close to the
feature’s actual location as shown in the following figure. Please do not repeat numbers
on a map sheet.

Example 2.2.9: Adding street name features in a congested area

2.2.10 Correcting feature location
This figure illustrates how to correct a feature location. Using the purple pencil, cross out
the existing feature on the map, and draw the feature in the correct location. Draw an
arrow pointing to the correct feature location. Label the feature with the feature’s name.

Example 2.2.10: Correcting the location of a street feature

Tribal Boundary and Annexation Survey Respondent’s Guide

13

2.2.11 Correcting feature name
This figure illustrates how to correct a feature name. Using the purple pencil, draw a line
through the incorrect feature name. Print the correct feature name next to the original
name as shown in the following figure.

Example 2.2.11: Correcting a street feature name

2.2.12 Annotating address range breaks
Addresses are stored in the Census Bureau’s spatial database as potential address ranges.
The BAS maps show the break in the potential address range created where a street is
bisected by a boundary. These address range breaks are shown because it is important
that the Census Bureau assigns the correct addresses to each governmental unit. Since
the BAS only corrects addresses at the boundary, the Census Bureau has other operations
that are designed to collect address information (see “Address Information Update” in
section 2.2).

Tribal Boundary and Annexation Survey Respondent’s Guide

14

If any of the following circumstances exist, use the purple pencil to add the address
ranges on both ends of the street:
•
•
•
•

A road where house numbers, street names and addresses were added or deleted
Our depiction of your boundary was corrected
A street was added that crosses a boundary
Our depiction of the potential address range break at the location of the boundary
is incorrect

Example 2.2.12: Adding a street feature and annotating with the name and address breaks

2.2.13 Deleting a feature
This figure illustrates how to delete a feature. Delete only if a feature is nonexistent or if
a street is impassable. Do not delete a street because your government is not responsible
for maintaining it.
Using the purple pencil, mark the beginning and end of the base feature to be deleted
with hatch (//) marks perpendicular to the feature as shown below. Cross out what is to
be removed using a string of “Xs”.

Example 2.2.13: Deleting a street feature

Tribal Boundary and Annexation Survey Respondent’s Guide

15

2.2.14 Adding a cul-de-sac or circle
This figure shows how to correctly represent a cul-de-sac or circle with illustrations of
each symbol and corresponding aerial photographs. The photographs are provided to
show the difference between cul-de-sacs and circles. A cul-de-sac is entirely paved,
whereas a circle has an area of unpaved ground within it.
To add a cul-de-sac or circle, draw the feature using the purple pencil following one of
the sketches below. Print the name of the associated street leading to the cul-de-sac or
circle.

Example 2.2.14: Adding cul-de-sac and circle features with annotations

Tribal Boundary and Annexation Survey Respondent’s Guide

16

2.2.15 Unnamed roads
If you find unnamed road segments on the maps, please provide the road names, if
known, using the purple pencil. If these are unnamed private roads, label them as “PR”.
Examples of private roads include driveways and unnamed roads in commercial or
industrial parks (see figure 2.2.15).

Example 2.2.15: Adding named and unnamed road features with annotation

2.2.16 Designating a geographic corridor to a street feature
The Census Bureau geographically codes addresses based upon the centerline of the
street. If this coding would result in addresses being assigned to the wrong entity, we
recommend the creation of a geographic corridor. A geographic corridor is an area that
only includes road surface and right-of-way and does not contain any structures
addressed to either side of the road. There are two types of geographic corridors:
•
•

An area where a road is not part of your reservation or off-reservation trust land
An area where only the road belongs to your reservation or off-reservation trust land

Tribal Boundary and Annexation Survey Respondent’s Guide

17

The following figures illustrate how to represent a geographic corridor on your maps. To
indicate a geographic corridor on your map, use the red pencil to draw a line on each side
of the road. Mark the beginning and end of each line with perpendicular hatch marks.
Write the letters “GC” beside each line. Please contact your Regional Census Center
with any questions regarding corridors or offsets (see Appendix 3 for a list of Regional
Census Centers).

Example 2.2.16.1: When designating a geographic corridor to the north and south of a road that is not part
of your reservation or off-reservation trust land, the addresses are moved from the non-reservation area to
your reservation or off-reservation trust land.

Example 2.2.16.2: When designating a geographic corridor to the north and south of a road that belongs to
your reservation or off-reservation trust land, the addresses are moved from your area to the nonreservation area.

2.2.17 Designating a geographic offset to a street feature
A geographic offset is an area claimed by an entity that is only on one side of a road,
includes the structures on both sides of the road and does not include any structures
addressed to that side of the road. We geographically code addresses based on the street
centerline.
Although we are aware that many governments base their legal boundaries on parcelbased, right-of-way mapping, the Census Bureau’s maps are based on spatial data that is

Tribal Boundary and Annexation Survey Respondent’s Guide

18

topologically integrated, which makes the maintenance of offsets inefficient. For this
reason, we request that you implement the Census Bureau’s centerline representation of
your boundary rather than providing an offset.
2.2.18 Inserting point and area features
These figures illustrate how to insert point and/or area features, including mountains and
airports. Using the purple pencil, draw the feature in the correct location, and print the
name of the feature as shown in the figures below.

Example 2.2.18.1: Adding a point feature

Example 2.2.18.2: Adding an area feature

3.0 Signing the Updated Maps
For each map sheet that has changes, fill in the Signature Box on each map sheet that you
have updated:
•
•

Print the date, your name, position and phone number
Sign your name

Example 3.0: Completing the signature box on the map sheet

Use the postage-paid envelope included in your BAS package to return the signed and
updated tribal maps and the BAS form to the Census Bureau. If after reviewing the tribal
BAS forms and maps it is determined that you do not have any changes to report, sign the
“No Change” postcard and return it to the Census Bureau.

Appendix 1: Paperwork Reduction Project
The Census Bureau estimates that the BAS review will take most respondents from 1 to 6
hours to complete. This includes the time needed to read the instructions, assemble
materials, organize and review the information, and report any needed changes. This
estimate is based on 80 percent of all areas having few or no changes. However, for
areas with many changes it may take 20 hours or longer to complete the survey. Please
send comments regarding this burden estimate or any other aspect of this collection of
information, including suggestions for reducing this burden to:
