2010 Census Local Update of Census Addresses Program


Will Your Community Be Ready?

The Local Update of Census Addresses program, also known as LUCA, is a decennial census geographic partnership program that will allow the U.S. Census Bureau to benefit from local knowledge in developing its Master Address File for the 2010 Census and yearly ongoing household surveys. Tribal, state, and local governments can contribute to a complete enumeration of their community by reviewing and commenting on the list of housing units and group quarters addresses that the Census Bureau will use to deliver questionnaires within their community.


Why is the LUCA program important to your community?


An accurate population count starts with an up-to-date and accurate address list. If a housing unit or group quarters address is listed on the Master Address File, it will ensure that the people residing at the address will be enumerated. A February 2003 Government Accountability Office report prepared for a congressional requestor indicated that in fiscal year 2000, about $283 billion in federal grant money was distributed to state and local governments by formula; states received their share of this money based in part on factors such as annual population estimates derived from the 1990 decennial census. When the population estimates were updated to reflect the 2000 census results, an additional $388 million in federal grant funding went predominately to the 23 states that had above-average estimate revisions. Clearly the stakes are high, and a complete count is vital to cities and towns nationwide.


How is the LUCA program administered?


The LUCA program is made possible by the Census Address List Improvement Act of 1994 (Public Law 103-430), which provides an opportunity for designated representatives of tribal, state, and local governments to review the addresses contained on the census address list. The program operates as follows:


·     The invited governments designate a LUCA liaison to review the portion of the census address list covering the area under its jurisdiction. The LUCA liaison will be subject to the same confidentiality requirements as census workers, which prohibit the disclosure of census information. The address list is confidential under Title 13 U.S. Code and participants must review a set of security guidelines and sign a confidentiality agreement promising to protect the confidentiality of the addresses.

·     The Census Bureau will send the LUCA liaison an address list from the Master Address File, corresponding maps, and address tallies.

·     In areas with city-style addresses the LUCA liaison can provide input regarding individual addresses on the list, as well as addresses missing from the list that should be added. The Census Bureau will verify this input during the Address Canvassing Operation and provide feedback to the participants about the results.

·     In areas with non-city-style addresses (e.g., rural route and box number or post office box numbers), the LUCA liaisons will provide input regarding the count of housing unit and group quarters addresses. The Census Bureau will visit each census block during the Address Canvassing Operation and update the census address list. The Census Bureau will provide the LUCA participants with an updated address list and maps during the feedback phase.

·     Public Law 103-430 allows the LUCA participants to appeal final Census Bureau decisions. All appeals must be adjudicated prior to Census Day to ensure that the housing unit is visited during the enumeration phase. An agency independent of the Census Bureau will review and decide on all appeals prior to Census Day, April 1, 2010.
