Overview of the 2010 Decennial Census LUCA Program
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 local, state, and tribal governments to review the addresses contained in the MTDB. 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, prohibiting the disclosure of census information. The address list is confidential under Title 13 U.S.C. and participants must review a set of security guidelines [PDF] / [MS Word] and sign a confidentiality agreement [PDF] / [MS Word] promising to protect the confidentiality of the addresses.
- The Census Bureau will send the LUCA liaison an address list from the MTDB, corresponding maps, and address tallies.
- In areas with city-style addresses (i.e. house number/street name), the LUCA liaison can comment on individual addresses on the list, as well as addresses missing from the list. The Census Bureau will verify this input during the Address Canvassing Operation and provide feedback to the participants about the results.
- In areas with noncity-style addresses (e.g., rural route and box number or post office box numbers), the LUCA liaisons can challenge the count of housing unit and group quarters addresses. The Census Bureau will visit each census block during the 2010 Census 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 the Census Bureau address determinations provided during the feedback phase. 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.
