OFFICE OF THE DIRECTOR

Recently, the U.S. Census Bureau invited the governor of your state 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 state,
local, and tribal 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. Your state’s participation in the LUCA Program can
help ensure that we achieve complete coverage in our enumeration of your state. If your state chooses
to participate in the LUCA Program, your state will be able to:
• Review and update the Census Bureau’s address list products for your entire state, or you may elect
to focus your review on selected areas within your state; or
• Submit your state’s address list to the Census Bureau in the Census Bureau specified
computer-readable format; and/or
• Review and update the geographic features in the Census Bureau’s geographic database.
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 state 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 software application that allows your state to update both the address list
materials and map information.
If your state has an active State Data Center, Federal/State Cooperative Program for Population
Estimates, and/or Geographic Information System coordinator, these established Census Bureau
partners may be good candidates for involvement in your LUCA effort.
We will supply your LUCA materials as soon as possible after we receive your state’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 states registering by
November 19, 2007.
