OFFICE OF THE DIRECTOR

Recently, the U.S. Census Bureau invited the chief executive/highest elected official of your 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 government’s participation in the LUCA
Program, your local knowledge can help ensure that we achieve complete coverage in our enumeration of
your jurisdiction. If your 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 on the Census Bureau maps.
The enclosed flyer, Will Your Community Be Ready for the 2010 Census Local Update of Census
Addresses (LUCA) Program? , provides an overview of the LUCA Program. The flyer answers questions
that may assist your government in deciding whether to participate in this important 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 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.
