The 2030 Census Local Update of Census Addresses Operation (LUCA) is an opportunity for officials of tribal, state, and local governments to engage with the 2030 Census by reviewing and commenting on the U.S. Census Bureau's address list prior to the 2030 Census.
While 2030 LUCA does not officially start until 2027, governments can choose to start preparing now.
LUCA is one of the Census Bureau’s Geographic Partnership Programs that supports the 2030 Census. This operation supports the Census Address List Improvement Act of 1994 (Public Law 103-430).
The Census Bureau relies on a complete and accurate address list to reach every living quarter and associated population for inclusion in the decennial census. LUCA provides an opportunity for governments to participate in reviewing this address list.
A LUCA review starts with governments reviewing their address count list by tabulation block and compare the totals to their own address list to determine if any discrepancies exist. Governments may find the address count meets expectations and no further review may be necessary.
Governments who agree to protect the confidentiality of our address list can receive the addresses for their jurisdiction. They have the option to provide suggestions to add residential addresses, delete residential addresses that do not exist or update the geographic location of residential addresses. The U.S. Census Bureau's address list includes street address or other descriptive information about the location where people live.
Governments who provide suggestions will receive feedback on their submission and will have the option to appeal results to the Office of Management and Budget (OMB).
