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 the area covered by your jurisdiction is entirely 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 any addresses contained within the boundary of any
federally-recognized American Indian reservation and/or off-reservation trust land on the Census
Bureau’s address list to any government other than the relevant tribal government. This policy is in
keeping with the Census Bureau’s recognition of 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 review, your government can still
participate in the LUCA Program if your government has a list of city-style (e.g., 101 Main Street)
addresses for your jurisdiction that you would like to submit.
Although your government cannot review the individual addresses for your jurisdiction, your government
can still participate in the LUCA Program through Option 3. Option 3 offers you an opportunity to submit
your local computer-readable address file (city-style addresses only) to the Census Bureau. For
reference, Option 3 participants receive the Census Bureau’s computer-readable address count list,
which contains address counts for each of the census blocks within your jurisdiction. If your government
chooses to participate in the LUCA Program, you will be able to:
• Submit your local address list containing only city-style addresses to the Census Bureau in the
Census Bureau specified computer-readable format; and
• Review and update your 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 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 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 submit your
address list. 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 address list, 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
