Dear (Name of Contact):
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 offreservation trust land(s) on the Census Bureau maps.

The enclosed flyer, Will Your Community Be Ready for the 2010 Decennial 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) CDROMs. 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 MAF/TIGER 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).
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 (RO e-mail address).
Sincerely,

Charles Louis Kincannon
Director
