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.
Our records indicate that a portion of the area covered by your jurisdiction is within the boundary of a
federally-recognized American Indian reservation and/or off-reservation trust land. For the LUCA
Program, the Census Bureau will not provide for your review the addresses on its list for that portion of
your jurisdiction. The Census Bureau provides addresses contained within the boundaries of
federally-recognized American Indian reservations and/or off-reservation trust lands only to the relevant
tribal government, in keeping with the unique government-to-government relationship between the
federal government and federally-recognized tribes. The Census Bureau nonetheless encourages tribal
governments to coordinate their address list review with, or to delegate (if they do not plan to
participate) review authority to, neighboring local governments or the state government. In the event that
the tribal government chooses not to coordinate its address list review for the portion of the area
covered by your jurisdiction, you can still help to improve the address list for your entire jurisdiction by
submitting potentially missing addresses as part of the LUCA Program.
The LUCA Program provides options for your government to:
• Review/correct the Census Bureau’s address list for the non-reservation/trust land portion of your
jurisdiction. If there are city-style addresses (e.g., 101 Main Street) that you think are likely missing
from the Census Bureau’s address list for the reservation/trust land portion of your jurisdiction (e.g.,
because they represent new construction), you can submit them as added addresses along with the
changes for the non-reservation/trust land area; or
• Submit your local address list of city-style addresses for all or part of your entire jurisdiction, including
the part that overlaps the tribal boundary, to the Census Bureau in the Census Bureau specified
format; and
• Review and update your legal boundaries and features on the Census Bureau maps.
Your government will not receive feedback on our disposition of any added addresses for the
reservation/trust land portion of your jurisdiction, or be able to appeal our determinations on these, but
we will include these addresses on our list for questionnaire delivery if we are able to validate them in
our field check.

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 in 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.
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 chief executive/highest elected official about
your government’s participation. Your chief executive/highest elected official received the forms required
to register to participate in the LUCA Program. If you have any questions regarding the LUCA Program,
please contact your Census Bureau Regional Office by telephone at 1-866-511-LUCA (5822) or via
e-mail at
Sincerely,

Charles Louis Kincannon
Director
