OFFICE OF THE DIRECTOR

Recently, the U.S. Census Bureau invited the highest elected official of your tribal government to
participate in the 2010 Decennial Census Local Update of Census Addresses (LUCA) Program. The
LUCA Program, authorized by the Census Address List Improvement Act of 1994 (Public Law 103-430),
provides tribal, state, and local governments the opportunity to review and update the Census Bureau’s
address list.
The accuracy and completeness of the Census Bureau’s address list is critical to the enumeration
process and the quality of the resulting census data. Through your tribal government’s participation in
the LUCA Program, your local knowledge can help ensure that we achieve complete coverage in our
enumeration of your reservation and/or off-reservation trust land(s). If your tribal government chooses to
participate in the LUCA Program, you can:
• Review and update the Census Bureau’s address list, or submit your address list to the Census
Bureau in the Census Bureau specified computer-readable format; and
• Review and update the legal boundaries and features of your reservation and/or off-reservation trust
land(s) on the Census Bureau maps.
The enclosed flyer, Will Your Community Be Ready for the 2010 Census Local Update of Census
Addresses Program? , provides an overview of the LUCA Program. The flyer answers questions that
may assist your tribal government in deciding whether to participate in this program. We have also
enclosed two computer-based training (CBT) CD-ROMs. One CBT CD-ROM provides background and
instructions on participating in the LUCA Program. The second CBT CD-ROM contains instructional
information on the Census Bureau’s Master Address File/Topologically Integrated Geographic Encoding
and Referencing Partnership Software (available free of charge to LUCA Program participants), a
geographic information system software application that allows your tribal government to update both
the address list materials and map information.
We will supply your LUCA materials as soon as possible after we receive your government’s completed
registration forms. You have 120 days from the date you receive your LUCA materials to complete
your review and submit your address list changes. We will accept registrations up until
December 31, 2007, but can guarantee the full 120-day review period only for governments
registering by November 19, 2007. If you register before October 31, 2007, you have the
opportunity to provide legal boundary updates along with your LUCA updates, and the Census Bureau
will not send you the 2008 Boundary and Annexation Survey package in January 2008.

The Census Bureau provides addresses located within the boundaries of federally-recognized American
Indian reservations and/or trust lands only to the relevant tribal government for review. If you want any
non-tribal governments with boundaries that overlap yours, or the state government, to participate in
your LUCA review, you can work with them to designate reviewers and then submit confidentiality
agreements for them to participate. If your tribe decides not to participate in the LUCA Program, we
encourage you to delegate your review to one of these other governments (with their prior concurrence).
The Census Bureau estimates that it will take between 105 and 1,575 hours to complete the LUCA
review depending on the number of addresses and the rate of address growth and change. This
includes the time needed to read the enclosed invitation materials and complete the registration forms,
and upon receipt of the LUCA materials to read the instructions, assemble and review the LUCA
materials and provide updates. 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, 4600 Silver Hill Road, Room 3K138, Washington, DC 20233, or you may e-mail
comments to ; use "Paperwork Project 0607-0795" as the subject. Please
include a copy of your message addressed to . Under the Paperwork Reduction
Act, we cannot ask you to respond to a collection of information unless it displays a currently valid
Office of Management and Budget (OMB) control number. The OMB number is found in the upper right
corner of each LUCA form.
Please review the enclosed information and contact your highest elected official about your tribal
government’s participation. Your highest elected official received the forms required to register to
participate in the LUCA Program. If you have any questions, please contact your Census Bureau
Regional Office by telephone at 1-866-511-LUCA (5822) or via e-mail at
