The 2010 Decennial Census Local Update of Census Addresses (LUCA)
Program
The Local Update of Census Addresses (LUCA) Program is an integral part of
the 2010 Census activities that utilizes the expertise of tribal, state, and local
governments to improve the accuracy and completeness of the address list used
to take the census.
The U.S. Census Bureau invited the chief executive/highest elected official of
your tribal government to participate in this program. Your tribal government
selected Option 2, Title 13 Address List Submission. This option allows you
to:
•
Review the Census Bureau’s address list for your reservation and/or
off-reservation trust lands including city-style 1 and noncity-style 2
residential addresses and the address count list. These lists are for
reference purposes only.
•
Submit your tribe’s address list of single or multiunit structure or group
quarters 3 city-style addresses only, in a predefined Census Bureau
computer-readable format. The Census Bureau will only accept your
address files (city-style addresses only) in the predefined format as
explained in Chapter 4.
1
The term city-style address is defined as an address that consists of a house number and street or road name, for
example, 201 Main Street. However, the address may or may not be used for the delivery of mail, and may include
apartment numbers/designations or similar identifiers. See Chapter 2 for a complete definition.
2
The term noncity-style address is defined as a mailing address that does not use a house number and street or road
name. This includes rural routes and highway contract routes, which may include a box number, post office drawers, or
general delivery. See Chapter 2 for a complete definition.
3
A group quarters is a place where people live or stay that is normally owned or managed by an entity or organization
providing housing and/or services for the residents. See Chapter 2 for a complete definition.
Option 2 Title 13 Address List Submission For Tribal Governments

Chapter 1: Introduction to the 2010 Decennial Census Local Update of
Census Addresses (LUCA) Program
•
Identify any additions, deletions, or corrections to boundaries, roads,
or other physical features on the Census Bureau paper maps or submit
an updated version of the digital map file (shapefile) provided by the
Census Bureau.
Background
The Census Address List Improvement Act
The Census Address List Improvement Act of 1994 (Public Law 103-430)
strengthened the Census Bureau’s partnership capabilities with tribal, state,
and local governments by expanding the methods the Census Bureau could use
to exchange address information. Designed to improve the accuracy of the
Census Bureau’s address list, the Act authorized the Census Bureau to provide
individual addresses to officials of tribal, state, and local governments who
agreed to conditions of confidentiality. Census 2000 marked the first
decennial census for which the Census Bureau could provide its address list
for review to governments that signed the required confidentiality agreement.
(See Appendix A for the terms of the LUCA Program Confidentiality and
Security Guidelines.)
The Census Bureau’s Master Address File (MAF)
In preparation for Census 2000, the Census Bureau created the Master Address
File (MAF) by merging the 1990 Address Control File 4 with the latest version
of the U.S. Postal Service’s (USPS) Delivery Sequence File 5 (DSF). The
MAF is a nationwide database of all addresses used to support many of the
Census Bureau’s operations. Besides containing mailing addresses and ZIP
Codes, an address record in the MAF also contains geographic information
about the location of addresses. In areas where there are noncity-style
addresses (e.g., rural route or post office box number), the address record may
contain additional information such as a location description.
The Topologically Integrated Geographic Encoding and Referencing
(TIGER®) Database
Address records in the MAF are linked to feature segments in the
Topologically Integrated Geographic Encoding and Referencing (TIGER®)
database. The TIGER® database includes the geographic coordinates and
names of all streets, water features, and other linear features, and boundaries
for all jurisdictions and statistical areas (census tracts6, census blocks 7, etc.)
4
The 1990 residential address list used to label questionnaires, control the mail response check-in operation, and
determine the nonresponse follow-up workload.
5
A computerized file containing all delivery point addresses serviced by the U.S. Postal Service (USPS). The USPS
updates the DSF continuously as its letter carriers identify addresses for new delivery points or changes in the status of
existing addresses.
6
A census tract is a small, relatively permanent statistical division of a county or statistically equivalent entity,
delineated for the purpose of presenting Census Bureau statistical data.
Option 2 Title 13 Address List Submission For Tribal Governments

Chapter 1: Introduction to the 2010 Decennial Census Local Update of
Census Addresses (LUCA) Program
used to tabulate decennial census data. The TIGER® database also includes
address ranges 8 along streets that have city-style addresses and the hierarchy
of census geographic area codes from the tribal level down to individual
census blocks (www.census.gov/geo/www/geodiagram.html). By linking
address records in the MAF to the TIGER® database, the Census Bureau is
able to identify street segments along which an individual address exists and
determine the geographic code that applies to that address.
The Census Bureau’s Geography Division regularly updates the MAF/TIGER
database from various sources. In addition to the USPS DSF, other sources of
updates include current household surveys, special censuses, and local sources.

A census block is a geographic area bounded by visible features, such as streets, roads, streams, and railroad tracks,
and invisible features, such as the boundaries of governmental units and other legal entities. Census blocks are the
smallest area for which the Census Bureau collects and tabulates statistical information.
8
Address ranges are the lowest and highest address numbers used to identify structures along each side of a street
segment that has city-style addresses. Usually one side of the street has even address numbers and the other side has
odd address numbers.

Introduction
Chapter 2 explains some of the terms and concepts used by the Census Bureau
and recommended strategies for your LUCA review. Refer to the Glossary or
visit the Census Bureau’s Web site at for additional terms
and definitions.
What is a Housing Unit?
A single-family house, townhouse, mobile home, trailer, apartment, group of
rooms, or a single room occupied as a separate living quarters or, if vacant,
intended for occupancy as a separate living quarters. A separate living
quarters is one in which one or more occupants (or intended occupants, if
vacant) live separate from any other individual(s) in the building and have
direct access to the living quarters without going through another living
quarters, such as from outside the building or through a common hall.
The following types of housing units are acceptable and should be included on
the address list you submit to the Census Bureau:
•
•
•
•
Houses, including townhouses, condominiums, and apartments.
Living quarters within an otherwise nonresidential structure such as an
apartment within a church, school, or business.
Mobile homes or trailers occupied as separate living quarters, or if
vacant, intended for occupancy as separate living quarters.
Any housing units under construction that will be habitable (closed to
the elements with final roof, windows, and doors) on Census Day,
April 1, 2010.

Chapter 2: Before You Begin Your Review
What are Group Quarters?
A place where people live or stay, in a group living arrangement, that is
owned or managed by an entity or organization providing housing and/or
services for the residents. This is not a typical household-type living
arrangement. These services may include custodial or medical care as well
as other types of assistance, and residency is commonly restricted to those
receiving these services. People living in group quarters are usually not
related to each other.
The following types of group quarters are acceptable and should be included
on the address list you submit to the Census Bureau:
•
•
•
•
•
•
•
•
•
•
Correctional facilities.
Juvenile facilities.
Nursing homes.
Hospitals with long-term care facilities.
College or university dormitories, fraternities, sororities.
Dormitories for workers.
Religious group quarters.
Shelters.
Group homes.
Any group quarters under construction that will be habitable (closed to
the elements with final roof, windows, and doors) on Census Day,
April 1, 2010.
Note: Housing units and group quarters can exist within the same structure.
Unacceptable Types of Housing Units and Group Quarters
Exclude the following unacceptable types of housing units and group quarters
addresses from your address list. Housing units and group quarters that are:
•
•
•

Option 2 Title 13 Address List Submission For Tribal Governments
Chapter 2: Before You Begin Your Review
Census Bureau Addresses
Residential and Nonresidential Addresses
The Census Bureau divides all addresses in two use types, residential and
nonresidential. Residential addresses are addresses of housing units and/or
group quarters where one or more people could live. Nonresidential addresses
are addresses of a structure or unit within a structure that do not serve as a
residence, such as commercial establishments, schools, government offices,
and churches.
Some structures can contain both residential and nonresidential units, even
though they have a single address such as an apartment over a store or a home
with an office.
Address Formats
City-Style Address Format
The Census Bureau classifies housing units and group quarters that have a
house number and street name address as city-style addresses. Examples
of city-style addresses include 212 Morning Star Road or 137 Eagle Lane,
Apt. 316. In some instances, the house number may also include an alpha
character such as W9254. These addresses are used for mailing or to
provide location for emergency services, such as police, fire, and rescue
(E-911 addresses).
City-style addresses for housing units in multiunit structures, such as
apartment buildings, contain a unit designator, for example, Apt 101 or
Suite D or a location designator such as “rear” or “basement” (Refer to
Appendix D, Unit Designation Abbreviations). The Census Bureau and
the USPS treat these designators as part of the housing unit address, and
they are included in each affected census address record.
Noncity-Style Address Format
The Census Bureau classifies addresses that do not include a house
number and/or a street name as noncity-style addresses. Noncity-style
addresses also may not include a complete house number and street name
address. The majority of noncity-style addresses are located in the more
sparsely settled areas of the United States; however, they may exist in
small- or medium-sized towns as well. Frequently used noncity-style
mailing addresses include:
• General delivery.
• Rural route and box number.
• Highway contract route and box number.
• Post Office box only delivery.
Option 2 Title 13 Address List Submission For Tribal Governments
9
Chapter 2: Before You Begin Your Review
Noncity-style addresses often do not follow any numeric sequence, and
may not be associated with the name of the street or highway on which
they are located. For this reason, the Census Bureau uses different
methods to compile the list of addresses for inclusion into the address list,
such as location descriptions (BRICK HSE w/ATTACHED GARAGE ON
RIGHT), structure points (geographic coordinates), and census geographic
codes (state code, county code, census tract number, census block
number).
Census Tract
Census tracts are small, relatively permanent statistical subdivisions of a
county or statistically equivalent entity, delineated for presenting Census
Bureau statistical data.
The proposed criteria for census tracts for the 2010 Census is that they contain
a minimum of 1,200 people with an optimal population of 4,000.
Census tract boundaries are delineated with the intention of being stable over
many decades, so they generally follow relatively permanent visible features.
However, they may follow governmental unit boundaries and other nonvisible features in some instances. Census tract boundaries never cross state
or county (or statistically equivalent entity) boundaries.
Each census tract has a unique number and contains numerous census blocks.
Census tract numbers contain up to a 4-digit number followed by a decimal
point and a 2-digit number for suffixed tracts, e.g., 1234.01. For census tracts
without a suffix, the number will contain a period with zero fill, e.g., 4567.00.
Leading zeros are not shown on Census Bureau materials.
Note: When using the Census Bureau shapefiles to geocode an address to a
Census Tract number, use the Tractlabel attribute field on the curtracts
(current tracts) shapefile.
Census Block
A census block is an area bounded by visible features such as streets, roads,
streams, and railroad tracks and nonvisible features such as the boundaries of
governmental units and other legal entities. A block is the smallest
geographic area for which the Census Bureau collects and tabulates statistical
data.
Census blocks may look like a city block or may be large and irregularly
shaped, depending upon features. The boundary of a state or a county is
always a block boundary.
Census blocks are numbered within census tracts and are unique to the census
tract to which they belong. Census block numbers consist of 4-digits, and
10
Option 2 Title 13 Address List Submission For Tribal Governments
Chapter 2: Before You Begin Your Review
may include a single alpha character suffix reflecting a boundary change or
added feature (e.g., 3001A and 3001B).
Note: The 2010 Census LUCA Program addresses are coded to current
census block/geography.
What is Geocoding?
In order to process your address submissions, the Census Bureau requires the
inclusion of census geographic code information. This link to census
geography is referred to as geocoding. Geocoding places an individual
address in its correct geographic location, which includes the correct state,
county, census tract, and census block codes.
Because the Census Bureau counts people where they live, census geographic
code information or geocodes support the systematic collection of data that
allows Census enumerators to locate an address. They are also important in
allocating data from questionnaire responses to the correct location. You
must include census geographic code information for the Census Bureau to
process your address submissions. The Census Bureau will not accept
addresses without census geographic codes (geocodes) including the state,
county, census tract, and census block codes.
Note: When using the Census Bureau shapefiles to geocode an address to a
Census Tract number, use the Tractlabel attribute field on the curtracts
(current tracts) shapefile.
You can find these census geographic codes on your LUCA materials.
Strategies for Reviewing the Census Bureau’s Address List
You must decide for yourself how to conduct the LUCA program review.
Consider your available time, the information you have readily available, and
the staff and computer resources you have. If resources are limited, the
Census Bureau recommends focusing on areas where addresses are more
likely to be missed or incorrect. For example:
•
•
•
•
•
•
•
•
Areas of new housing construction.
E-911 address conversion areas.
Areas that have changed from single-family homes to multi-family
homes and vice versa.
Warehouses that have been converted to residential lofts.
New mobile home parks or new scattered mobile homes.
Apartment buildings with irregular or missing numbering schemes for
the individual units.
Newly acquired trust land.
Addresses near governmental boundaries.

There are many possible sources of address information. Some of these
sources may not match the Census Bureau’s address list exactly, but they are a
good indication of where change is taking place and can help you identify
addresses that you need to add to the your address list. The following list
provides suggestions for address source materials:
•
•
•
•
•
•
•

New housing construction or building permits (include units that are
under construction only if final roof, doors, and windows will be in
place on Census Day, April 1, 2010).
E-911 address files.
Housing inspection records.
Planning or zoning records.
Tribal utility records.
School enrollment records.

Opening the Files
The File Formats
Introduction
The Census Bureau’s address list and address count list files for your
reservation and/or off-reservation trust land are included on your CD-ROM.
This chapter discusses how you must protect the Census Bureau’s computerreadable address information and explains:
•
•
•
File names and formats.
Software requirements.
How to open the files.
Protecting Census Bureau Address Information
The most efficient method to review and match your tribe’s address list to the
Census Bureau’s address list is to copy the Census Bureau’s address file onto
a computer hard drive or a network server in a useable format. You must first
ensure the protection of the Census Bureau’s Title 13, U.S.C. address
information including your Census Bureau computer-readable address file, all
address list paper copies, and maps (including copies) containing structure
points. (Structure points will be displayed on the address list and maps,
where applicable, for the Feedback phase of the program.)
The LUCA tribal liaison must restrict access to confidential Census address
information to only those individuals who have signed the Confidentiality
Agreement. This includes all reviewers and anyone with access to Title 13
materials (See Appendix A for the terms of the Confidentiality and Security
Guidelines). If you need to add additional reviewers during your LUCA
review, a blank Confidentiality Agreement Form is included in Appendix B.
Be sure additional reviewers have read and understand the Confidentiality and
Security Guidelines, Appendix A, before signing and returning the
Confidentiality Agreement Form to the Census Bureau. For detailed
information see Appendix A, Confidentiality and Security Guidelines.
Operating systems, programs, applications, and data related to the review of
Census Bureau addresses must be accessible only to LUCA program tribal

Count List
liaisons and reviewers. The automated data processing (ADP) system should
restrict the read, write, delete, and execute functions applicable to the Census
Bureau’s address information.
The ADP system must use log-on routines that require a user-ID and
password that conform to the following guidelines:
•
Assign a unique user-ID and password for each LUCA Program
liaison and reviewer.
•
Passwords must consist of at least eight (8) nonblank characters
consisting of at least one alphabet letter and either one number or
one special character ($,*, &). No more than six consecutive
characters (AAAAAA) may appear in the password, and then only
once.
•
Reject passwords that are the same as the user-ID or used within
the last 6 months.
•
Encrypt passwords.
•
Disable passwords after three bad attempts.
•
Do not display passwords on terminals or printers.
•
Change passwords every 90 days (more frequent change is
optional) or immediately, if compromised.
•
On new accounts, change the assigned password to a unique
password the first time users log on.
•
The ADP system must display a warning log-on feature.
Computer screens must display a warning that states:
**WARNING*WARNING*WARNING**

•
If you place Census Bureau address information on a shared
computer system, construct electronic security profiles to allow
only the LUCA tribal liaison and reviewers access to the Census
Bureau’s address information. Test your security to ensure that
only the LUCA tribal liaison and reviewers are permitted access to
the Census Bureau’s address information.
•
Lock all rooms containing computers and all associated media
during non-work hours.
•
Do not leave computers with Census Bureau address information
unattended during work hours. Log-off the computer or lock the
room whenever you leave.
•
Label any computer diskettes, CD-ROMs, DVDs, tapes, cartridges
or other computer storage media containing Census Bureau address
information with the following:
“This document contains information the release of which is
prohibited by Title 13 U.S.C. and is for Bureau of the Census
official use only.”
•
If backup is necessary, do not send the tapes, cartridges, or disks
off-site. Store them in a secured area. Do not mix, store, or
back-up LUCA data with other data.
•
Clear magnetic media (tapes, disks, hard drives) containing
Census Bureau address information before reuse. To clear
magnetic media, overwrite all Title 13 data three times at a
minimum using a commercial disk utility program or degauss
using a commercial degausser.
•
Program any software you develop for displaying the Census
Bureau addresses to label each affected page of a printout
containing Census Bureau address information with the following:
“This document contains information, the release of which is
prohibited by Title 13 U.S.C. and is for Bureau of the Census
official use only.”
The File Names
The address list (AL) file contains all of the residential addresses currently
recorded by the Census Bureau for your reservation and/or off-reservation
trust land. The address count list (ACL) file contains the residential address
counts for each census block within your reservation and/or off-reservation
trust land. The name of each of the files is:
1. Address List–LUCA_AL_TRxxxxTAyyyy.txt
2. Address Count List–LUCA_ACL_ TRxxxxTAyyyy.txt

Software Requirements
The files you receive are pipe-delimited ASCII text files, meaning they can be
viewed and read as letters and numbers with a text editor. All spreadsheet and
database programs can read and understand these text files.
Many commercial spreadsheet and database programs can open the LUCA
files. Use spreadsheet programs such as Microsoft Excel or Lotus 123 to
open, view, and edit small files. For larger files, use a database program such
as Corel Paradox, QuattroPro, Microsoft Access, or dBase 10.
Note: Some computer programs that can open and view pipe-delimited text
files cannot save an edited file in the correct format. Make sure your program
has the ability to save or export a file with pipe-delimited fields. Call the Help
Desk toll free at 1-866-919-5822 if you need assistance or more information.
Opening the Files
Refer to the readme.txt file for instructions on opening the encrypted selfextracting address list. A case-sensitive password is required to open the file.
The Census Bureau will mail the password to you, separate from your LUCA
materials.
•
The Census Bureau recommends that you make a copy of each of the
files and place them on the hard drive of a computer that is password
protected. This will preserve the original files should you need to look
at an original record or require another original copy of the file.
•
To help keep your work organized, create a new directory or new
folder on your hard drive. Copy the files from the CD-ROM into that
directory or folder.
•
When you open the text files with your application, some spreadsheets
and databases will prompt you to supply some information about the
file. Be prepared to provide the application program with the
following:
c

Introduction
The Census Bureau provides you with one set of paper maps or shapefiles as a
reference for locating and geocoding individual addresses and for updating and
correcting your reservation’s and/or off-reservation trust land’s features and
boundaries. If you requested to receive paper maps, you also receive a Map
Sheet to Block Number Relationship List that identifies the map sheet(s) on
which each census block is located. See Figure 5.2, The Map Sheet to Block
Number Relationship List.
Reading a Census Bureau Paper Map
There are three types of paper map sheets:
1. Index Sheets
2. Parent Sheets
3. Inset Sheets
Index Sheets – for reference (if more than one map sheet)
•
Cover the entire extent of your reservation and/or offreservation trust land.
•
Divided into numbered grids.
Each numbered grid area corresponds to area covered by a
parent sheet.
Used with reservations and/or off-reservation trust land
containing more than one parent sheet.
•
•
32
Option 2 Title 13 Address List Submission For Tribal Governments
•
Index sheets are for reference; please do not make updates to
the index maps because the updates are difficult to incorporate
into our database due to the smaller scale.
Parent Sheets – for map updates
•

Examples of Feature Updates
Adding a new street and associated address ranges 11 on the paper
map
During your review, you may find addresses missing from the Census
Bureau’s address list that are on streets that are partially or entirely
missing from the maps.
For example, Cedar Dr is a new street with newly constructed housing
units in census tract 2623.00 and census block 1027. The addresses
are missing from the address list and the street is missing from the
map.
Figure 5.3: Adding a New Street on the Map

3.
4.
5.
Using a purple pencil, draw the location of the new street on
the map.
Print the street name.
Print the address ranges for each side of the new street.
Print the address breaks where Cedar Dr intersects B St (41-43)
and E St (108-110).
Be sure that your address list matches map corrections.
11
Address ranges are the lowest and highest address numbers used to identify structures along each side of a street
segment. Usually one side of the street has even address numbers and the other side has odd address numbers.

Chapter 5: The Census Bureau Maps
Correcting a street name on the paper map:
The Census Bureau’s address list and map below incorrectly shows C
St instead of Cedar Dr, the correct street name. The map also does not
list the alternate name for the street, which is County Road 9 (Co Rd
9).
Figure 5.4: Correcting a Street Name on the Paper Map
1. Using a purple pencil, cross out the incorrect name, C St, and
print the correct name, Cedar Dr above it.
2. Use double hatch marks to show the extent of the name change.
In this instance, the entire street needs to be corrected.
3. Print the alternate street name (Co Rd 9) in parentheses.
4. Be sure that your address list matches map corrections.

Option 2 Title 13 Address List Submission For Tribal Governments
Chapter 5: The Census Bureau Maps
Correcting the location of a street on the paper map:
The address list shows 101 through 106 N Jefferson St as located in
Census Block 2014. According to your address list sources, N
Jefferson St is located east of Jefferson St in Census Block 2015.
At this location, N Jefferson St includes an odd numbered address
range 12 from 101 through 105 on the west and an even numbered
address range from 100 through 106 on the east.
N Jefferson St intersects Jefferson St between address numbers 502
and 504 13.
Figure 5.5: Correcting the Location of a Street on the Paper Map
1. Using a purple pencil, cross out the incorrect location of N
Jefferson St with a series of “Xs.”
2. Redraw N Jefferson St in its correct Census Block, 2015, and
print the street name and address ranges along the moved
street.
3. Draw an arrow to the correct location of N Jefferson St
4. Print the address breaks where N Jefferson St intersects
Jefferson St between address numbers 502 and 504.
5. Be sure that your address list matches map corrections.
12
Address ranges are the lowest and highest address numbers used to identify structures along each side of a street
segment that has city-style addresses. Usually one side of the street has even address numbers and the other side has
odd address numbers.
13
Address breaks are the city-style addresses on each side of a boundary or at an intersection of a street with another
street or feature.

Deleting a street on the paper map
In this example, there are two streets and their associated addresses to
delete.
1. All of the housing units along a portion of Hillsview Rd
between Census Blocks 1005, 1007, and 1008 have been
demolished, and this section of the street no longer exists.
2. All of the houses on Dakota St between Census Blocks 1002,
1003, 1004, and 1005 have been demolished. The entire street
no longer exists.
Figure 5.6: Deleing Streets on the Map
Deleting a section of Hillsview Rd on the map:
1. Use a purple pencil to “X” out the section of Hillsview Rd that
no longer exists.
2. Use double hatch marks to define the extent of the deleted
segment when deleting only part of the street.
Deleting Dakota St on the map:
3. To delete Dakota St, “X” out the entire street and put a purple
line through the name.
4. Be sure that your address list matches map corrections.

Shapefiles
Shapefiles require the use of GIS software. The Census Bureau provides
county-based shapefile layers in Environmental Systems Research Institute 14
(ESRI) shapefile format. Participants that submit shapefiles with feature
updates must follow Census Bureau requirements.
To geocode addresses to census blocks, a tabblock shapefile is included.
The shapefiles, created from the MAF/TIGER database, allow you to submit
map feature updates electronically. All linear features in the MAF/TIGER
database are contained in the edges shapefile. Use the edges shapefile to add,
delete, or change linear feature attributes.
In addition to an edges shapefile, the Census Bureau provides shapefiles for
legal boundaries that you may edit. Refer to the Digital BAS Respondent
Guide: Tribal Digital BAS Guide included with your LUCA materials for
boundary updates.
For more details on the contents of the shapefiles, view the readme.txt file that
is included on the CD-ROM containing your shapefile
Submitting Shapefile Feature Information
In order to submit digital feature information, you must have a GIS capable of
importing ESRI shapefiles, editing the features, and exporting layers back into
ESRI shapefile format.
The Census Bureau’s Shapefile Coordinate System and Projection
Information
All shapefiles provided by the Census Bureau are in the following
unprojected geographic-based coordinate system:
•
•
•
•
•
•
•
•
GCS_NAD83
Angular Unit: Degree (0.017453292519943299)
Prime Meridian: Greenwich (0.000000000000000000)
Datum: D_North_American_1983
Spheroid: GRS_1980
Semi-major Axis: 6378137.000000000000000000

Inverse Flattening: 298.257222101000020000
14
All shapefiles provided by the Census Bureau are in Environmental Systems Research Institute (ESRI) format. The
use of brand names does not represent an endorsement of a company or its products by the U.S. Government. Due to
the wide use of ESRI products by our partners in the GIS community, and ubiquitous use of the shapefile format as a
medium for GIS data exchange, the Census Bureau provides data in shapefile format.
Option 2 Title 13 Address List Submission For Tribal Governments

Chapter 5: The Census Bureau Maps
General File Setup Guidelines
Upon receipt of your shapefiles, follow the setup guidelines listed
below before beginning actual updates:
•
Open the CD and enclosed zip file to ensure it contains the
shapefiles for your entity.
•
Copy and decompress the shapefiles to a directory on your
server or hard drive.
•
Open the shapefile in a GIS.
Note: If you are using GIS software that does not contain a shapefile
translator, please contact the Help Desk toll free at 1-866-919-5822 for
further instructions.
Changing Our Coordinate System to Match Yours
Our files are in GCS_NAD83 format. Please feel free to project these
files into your local coordinate system projection. Most GIS software
packages contain projection wizards, or something similar, allowing
the user to transform file coordinate systems and projections. For
example, if your office uses ArcView to update files, please activate
and utilize ArcView’s ‘Projection Utility Wizard’ extension. If using
ArcGIS, please use its “Projection Utilities” in ArcToolbox.
MAF/TIGER extract shapefiles contain defined projection information
in the *.PRJ file. Both ArcView and ArcGIS access the *.PRJ file for
projection information; therefore, there is no need for you to define
these parameters before changing the file coordinate system.
In addition, if your files are in a datum other than NAD83, you must
geographically transform our files to match your datum. Most GIS
software has tools for performing geographic transformations on files.
If you transform the files to your local coordinate system, we request
that you convert them back to the GCS_NAD83 format before
submitting the file to the Census Bureau. If you encounter problems
transforming our files, please contact the Help Desk toll free at
1-866-919-5822 for assistance.
Feature Information
If you have reviewed your features using our shapefiles and have
determined that the Census Bureau needs to add, remove, or rename
features in a given area, you may submit your modifications in a
separate layer. To move or correct the shape of a feature, first delete
the feature then add the correction.
42
Option 2 Title 13 Address List Submission For Tribal Governments
Chapter 5: The Census Bureau Maps
Use the appropriate update code located in the coding scheme as
shown in Figure 5.9 to identify the type of feature modification needed
for submission.
If any issues arise with the shapefiles that you submit, your Census
Bureau Regional Office will attempt to contact you to clarify the issue.
If clarification is not made prior to our project deadline, the updates
may not be incorporated into MAF/TIGER. Your updates are
considered temporary until their existence is confirmed during our
Address Canvassing Operation.
Updating the Feature Shapefile
Use the edges layer to provide all feature updates to the Census
Bureau’s shapefile.
Edges Layer Data Dictionary
The data dictionary defines the attribute information for each feature
contained in the edges layer. Refer to Figure 5.7 for an example of the
edges layer data dictionary.

Metadata
Metadata Requirements
Metadata that describe the data content, coordinate system/projection,
author, source, and other characteristics of GIS files are critical for Census
Bureau staff to efficiently and accurately process files. The Census
Bureau requires that a metadata text file accompany every GIS file and
layer submitted.
The Federal Geographic Data Committee’s (FGDC) Content Standard for
Digital Spatial Metadata provides a national standard that enables the datasharing public to easily locate critical information about a file and ensure
that no critical information is omitted inadvertently when creating
metadata. For this reason, the Census Bureau requests that metadata be
submitted using this standard. For information about the FGDC and its
geospatial metadata standards, please visit .
The Census Bureau requires that the following sections of the FGDC
metadata form be completed:
•
Citation (information about the originator, publication date, title
edition, and other publications or information).
•
Description (section that contains an abstract describing your data
set).
•
Time period of content (section that describes the vintage of the
data).
•
Spatial domain (information about bounding coordinates).
•
Point of contact (general contact information).
•
Data quality information (information about attribute accuracy).
•
Spatial reference information (section on coordinate
system/projection of the data set).
•
Entity and attribute information (section that describes the contents
of your table).
To help you fulfill the requirement of filling out and submitting metadata,
the Census Bureau suggests visiting the United States Geological Survey
(USGS) Web site at . This site contains useful
information about FGDC compliant metadata, from which one can read
about metadata frequently asked questions, view FGDC metadata
examples, and connect to other FGDC related Web pages. The USGS's
metadata URL is . Moreover, if you are using
Arc/Info, the following link points to a useful Arc Macro Language
(AML) tool that, when executed, completes most of the required sections
50
Option 2 Title 13 Address List Submission For Tribal Governments
Chapter 5: The Census Bureau Maps
of the metadata form automatically
. (This AML is a
product of the Illinois State Geological Survey.)
Note: ESRI’s ArcCatalog also has an embedded program that uses the
FGDC standard in its creation of geospatial metadata.
If you have questions regarding the metadata requirements, please contact
the Census Bureau at the Help Desk toll free at 1-866-919-5822.
Digital File Submission
Use the following as a guide to ensure that you have included all the
required layers.
•
Name the feature update layer:
LUCA__LN_changes.shp
The feature update layer must include:
o A value in its “CHNG_TYPE” field that indicates the type
of change.
o Only feature updates (do not include unmodified features).
•
Include the appropriate metadata.
Boundary and Annexation Survey (BAS)
The Census Bureau conducts the Boundary and Annexation Survey (BAS)
each year to determine the inventory of correct names, legal descriptions, and
legal boundaries of federally recognized American Indian reservations and/or
off-reservation trust lands, counties and equivalent entities, minor civil
divisions, and incorporated places. Title 13, U.S.C. authorizes this voluntary
survey. Specifically, the Census Bureau requests up-to-date boundary
information for tribal governments and information on the legal actions
associated with the changed boundaries. The Census Bureau enters all
boundary and area information obtained through the BAS into the TIGER®
database so that all subsequent map and Census address list products reflect
these changes.
During your LUCA review, you may find that the boundary for your
reservation and/or off-reservation trust land does not depict the correct current
location. You may use your LUCA maps to provide updates to your legal
boundaries.
If you registered to participate in the LUCA program before October 31, 2007,
you received your 2008 BAS materials with your LUCA program materials.

Destroying Census Bureau Title 13, U.S.C. Materials
Program Conclusion
At the conclusion of the appeals process, you must return to the Census
Bureau or destroy all Title 13, U.S.C. address lists and all copies. If you
choose to destroy Title 13, U.S.C. materials, you must follow the Census
Bureau’s specific guidelines for destroying Title 13 materials as described
below or in the Confidentiality and Security Guidelines (See Appendix A).
The designated tribal liaison is required to verify the return or destruction of
any remaining Title 13 materials, both paper and computer-readable (i.e. paper
copies, backup files, etc.) by signing and returning to the Census Bureau the
Return or Destruction of Title 13, U.S.C. Materials form found in Appendix H.
If you return your Title 13 materials to the Census Bureau, this form must be
included. All LUCA Program reviewers and anyone with access to Title 13
materials (includes all persons who signed the Confidentiality Agreement
Form) are required to sign and date this form once the appeals process has
concluded. Should any tribal liaison, reviewer, or anyone with access to Title
13 materials leave before the completion of the LUCA Program, they are
required to sign out of the program by signing and dating this form. If any
tribal liaison or reviewer leaves and fails to sign and date this form, the current
tribal liaison can sign out on their behalf.

APPENDICES
Appendix A
Confidentiality and Security Guidelines
The law requires the U.S. Census
Bureau to maintain the confidentiality
for all of the information that it collects.
The Census Bureau takes its
responsibility to protect the
confidentiality of the information it
collects very seriously. Respondents
place their trust in the Census Bureau
each time they complete a survey or an
interview. This trust in confidentiality is
critical to the success of the Census
Bureau’s mission to collect and report
the most accurate data possible. To
uphold the law, the Census Bureau
requires that all individuals who work
with the Census Bureau’s confidential
materials read, understand, and agree to
abide by the confidentiality and security
guidelines outlined below.
thereof to examine the individual
reports.”
Section 214 of the Code and the
Uniform Sentencing Act of 1984 set the
penalty for the wrongful disclosure or
release of information protected by Title
13 at a fine of not more than $250,000
or imprisonment for not more than
5 years, or both.
To implement this law, all Census
Bureau employees (both temporary and
permanent) take an oath to maintain the
confidentiality of the census information
they encounter in their work. Census
information includes:
•
Everything on a completed or
partially completed questionnaire or
obtained in a personal or telephone
interview.
•
Individual addresses maintained by
the Census Bureau that Local
Update of Census Addresses
(LUCA) Program liaisons review.
•
Maps that identify the location of
individual housing units and/or
group quarters (“structure points”).
Why Address Information Is Protected
Title 13, United States Code (U.S.C.),
provides for the confidential treatment
of census-related information. Chapter
1, Section 9 of the code states:
“Neither the Secretary, nor any other
officer or employee of the Department of
Commerce or bureau or agency thereof,
or local government census liaison,
may, except as provided in section 8 or
16 or chapter 10 of this title…
1) use the information furnished under
the provisions of this title for any
purpose other than the statistical
purposes for which it is supplied; or
2) make any publication whereby the
data furnished by any particular
establishment or individual under
this title can be identified; or
3) permit anyone other than the sworn
officers and employees of the
Department or bureau or agency
Title 13 of the U.S.C. does not protect
generalized address information, such as
the address range data available in the
Census Bureau’s digital shapefile
products.
In 1994, the U.S. Congress amended
Chapter 1 of Title 13 to allow local
government designated census liaisons
to review the Census Bureau’s address
list for their area. This amendment
recognizes the important role that local
knowledge and participation can play in
building and updating an accurate,
comprehensive census address list. In
Appendix A: Confidentiality and Security Guidelines
58
amending this chapter, the Congress
reaffirmed the confidential nature of
address information.
The Confidentiality Agreement
Each participating government must
designate a primary liaison. The
primary liaison, all reviewers, and
anyone with access to Title 13, U.S.C.
materials must understand and sign the
Confidentiality Agreement. The Census
Bureau considers all individuals who
have access to the Census Bureau’s
address information and maps showing
the location of housing units and group
quarters, liaisons. Therefore, all Option
1 and Option 2 2010 Decennial Census
LUCA Program liaisons, reviewers, and
anyone with access to Title 13 materials
must sign the Confidentiality
Agreement.
Signatures on this form constitute an
agreement by each individual to abide
by the security guidelines outlined
below. While access to Title 13
protected information is temporary, the
commitment to keep the information
confidential is permanent.
•
The Census Bureau will not
deliver the address list materials
to Option 1 and Option 2
participants until we have
received a completed and signed
Confidentiality Agreement and
Self-Assessment Form.
•
Although you may have prior
confidentiality agreements on file
at the Census Bureau, these will
not fulfill the requirements of the
2010 Decennial Census LUCA
Program.
Security Guidelines
The Census Bureau recognizes the fact
that the implementation of these
guidelines may vary slightly from one
59
participant to another. Regardless, the
result must be the same for each
participant – nondisclosure of
information protected by Title 13,
U.S.C.
The primary liaison accepts the
responsibility for protecting and
safeguarding the LUCA program
materials covered by Title 13, U.S.C.
This includes any list that shows
individual Census Bureau addresses
and any Census Bureau map or digital
file that shows individual housing units
and/or group quarters location
(“structure points”). The primary
liaison must restrict access to the Census
Bureau’s address information to those
individuals who have signed the
Confidentiality Agreement. The liaison,
reviewers, and anyone with access to
Title 13 materials must sign the
Confidentiality Agreement.
As you read the Census Bureau’s
security requirements, keep in mind the
important role security plays in the
overall responsibilities of each LUCA
program liaison, reviewers, and anyone
with access to Title 13 materials. The
Census Bureau must have your full
cooperation and commitment to
following these guidelines. Together,
we will maintain the confidential
information entrusted to the Census
Bureau by the Congress and the
American public.
Protecting Census Bureau Address
Information
The Census Bureau will conduct
training workshops covering all aspects
of the LUCA program. In addition, the
workshops will provide the participating
governments with an opportunity to
review the security guidelines and
safeguards to protect against illegal use
of Census Bureau address information.
Census Bureau staff conducting the
workshops will provide information to
Appendix A: Confidentiality and Security Guidelines
help you decide who in your
organization needs to have access to the
Census Bureau’s Address List and will
review the civil and criminal penalties
for improper or illegal use of the data.
Onsite Visits
To ensure that participating entities or
organizations are maintaining adequate
security safeguards, the Census Bureau
may make on-site visits to review your
government or organization’s security
procedures. The Census Bureau will
strive not to disrupt your office
operations. A typical visit would
include a review of:
•
Storage and handling of Census
Bureau address information.
•
Employee access to Census Bureau
address information.
•
The physical safeguard of the
computers, rooms, and buildings
where the Census Bureau address
information is stored.
•
Instructions to employees about
security.
•
Data processing operations
(including use of passwords).
•
Employee awareness of their
responsibilities to protect the
confidentiality of Census Bureau
addresses.
•
During work hours, do not leave a
room unattended where Census
Bureau address information is
stored. Lock the room whenever
you leave.
•
Do not leave Census Bureau address
information unattended at your
desk. Return any Title 13 data to
secure storage when you are not
using it.
•
Only make copies of the
information necessary to complete
your task. Do not leave the copying
machine unattended while making
copies. All copied material
containing Title 13 information
must bear the statement:
“This document contains
information, the release of which
is prohibited by Title 13, U.S.C.,
and is for U.S. Census Bureau
official use only. Wrongful
disclosure or release of
information can be punished by
fine or imprisonment (Public
Law 99-474).”
•
To FAX a document containing
Census Bureau address information
to a Census Bureau location, make
sure the document is properly
labeled with the disclosure
statement: “DISCLOSURE
PROHIBITED BY Title 13,
U.S.C.”, verify the FAX number
before sending, and arrange for a
Census Bureau employee to be at
the FAX machine to receive it and
acknowledge receipt.
•
Do not disclose precise or even
anecdotal information about Census
Bureau addresses or locations to
anyone who has not signed the
Confidentiality Agreement Form or
is not a Census Bureau employee.
Protecting Paper Copies of Census
Bureau Address Information and Maps
•
Keep all Census Bureau address
information in a locked room during
non-work hours. If possible, store
the Census address materials and
maps showing structure points in
locked desks or cabinets.
Appendix A: Confidentiality and Security Guidelines
60
Protecting Computer-Readable Census
Bureau Address Information and Maps
Operating systems, programs,
applications, and data related to the
review of Census Bureau addresses must
be accessible only to LUCA program
liaisons and reviewers. The automated
data processing (ADP) system should
restrict the read, write, delete, and
execute functions applicable to the
Census Bureau’s addresses.
The ADP system must use log-on
routines that require a user-ID and
password that conform to the following
guidelines:
•
Assign a unique user-ID and
password for liaisons, reviewers,
and anyone with access to Title 13
materials.
•
Passwords must consist of at least 8,
nonblank characters consisting of at
least one alphabet letter and either
one number or one special character
($,*, &). No more than six
consecutive characters (AAAAAA)
may appear in the password, and
then only once.
•
Reject passwords that are the same
as the user-ID or that have been
used within the last 6 months.
•
Encrypt passwords.
•
Disable passwords after three bad
attempts.
•
61
Do not display passwords on
terminals or printers.
•
Change passwords every 90 days
(more frequent change is optional)
or immediately, if compromised.
•
On new accounts, the user must
change the assigned password to a
unique password the first time they
log on.
The ADP system must display a
warning log-on feature. Computer
screens must display a warning that
states:
**WARNING*WARNING*WARNING**
YOU HAVE ACCESSED A COMPUTER

GLOSSARY
Address breaks – Address breaks are the city-style addresses on each side of a boundary
or at an intersection of a street with another street or another feature.
Address count list – Identifies the number of housing unit addresses and group quarters
addresses on the Census Bureau’s address list for each census block within a reservation.
Address range – The lowest and highest address numbers used to identify structures
along each side of a street segment that has city-style addresses. Usually one side of the
street has even address numbers and the other side has odd address numbers.
American Indian area – A Census Bureau term that refers to any or all of the following
entities: American Indian reservation, American Indian off-reservation trust land,
Oklahoma tribal statistical area, joint use area, American Indian tribal subdivision, tribal
designated statistical area, and state designated American Indian statistical area.
American Indian off-reservation trust land – The United States holds title for specific
areas in trust for the benefit of federally recognized American Indian tribes (tribal trust
land) or for individual American Indians (individual trust land). Although trust land may
be located on or off a reservation, the Census Bureau recognizes and tabulates data only
for off-reservation trust land. Census data always associate off-reservation trust land with
a specific federally recognized reservation or tribal government.
American Indian reservation – 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. It covers territory over which a tribe(s) has primary
governmental authority. Its boundary is defined by tribal treaty, agreement, executive or
secretarial order, federal statute, or judicial determination. 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 tribal subdivision – A legal subdivision of a federally-recognized
American Indian reservation, off-reservation trust land, or Oklahoma tribal statistical
area. These entities are internal units of self-government or administration that serve
social, cultural, and/or economic purposes for American Indians.

Census block – A geographic area bounded by visible features, such as streets, roads,
streams, and railroad tracks, and invisible features, such as the boundaries of
governmental units and other legal entities. A census block is the smallest area for which
the Census Bureau collects and tabulates statistical information. Census blocks are
numbered within census tracts and are unique to the census tract to which they belong.
Census block number –Census block numbers contain a 4-digit number plus a 1-digit
alpha character, if applicable, e.g. 3001A. Suffixes, such as 2011A and 2011B, reflect

statistical data. Census tracts never cross the boundary of a county or statistically
equivalent entity, but may split other geographic entities; e.g., minor civil divisions and
places.
Census tract number – Unique numbers to identify census tracts within a county or
statistically equivalent entity. Census tract numbers contain up to a 4-digit number
followed by a decimal point and a 2-digit number for suffixed tracts, e.g., 1234.01. For
census tracts without a suffix, the number will contain a period with zero fill, e.g.,
4567.00. Leading zeros are not shown on Census Bureau maps.
Chief executive/highest elected official – The person most responsible for the
governmental activities of a tribal government. This person receives the LUCA Program
invitation letter, and must designate a LUCA tribal liaison, if desired.
City-style address – An address that consists of a house number and street name; for
example, 201 Oak Street. The address may or may not be used for the delivery of mail
and may include apartment numbers/designations or similar identifiers.
75

location entities (places and county subdivisions), and American Indian and Alaska
Native areas.
Geocodes – Codes that place an individual address in its correct geographic location,
which includes the correct state, county, census tract, and census block codes.
Geographic Information System (GIS) – A computer system for the storage, retrieval,
and maintenance of information about the points, lines, and areas that represent the
streets and roads, rivers, railroads, geographic entities, and other features on the surface
of the Earth-information that previously was available only on paper maps.

without going through another living quarters, such as from outside the building or
through a common hall.
Legal boundary – The legally defined boundary of a governmental unit, usually
referring to a county, minor civil division, or incorporated place. The legal boundary
identifies the area within a tribal government's jurisdiction, and thus bounds the area of
LUCA responsibility.

liaison. A person voluntarily appointed by the chief executive/highest elected official of
each reservation to review the Census Bureau’s address list and maps against local
records to identify differences.
