2020 Census Local Update of Census Addresses Operation

The 2020 Census Local Update of Census Addresses Operation (LUCA) is a voluntary decennial census operation. LUCA is the only opportunity prior to the 2020 Census for tribal, state, and local governments (including the District of Columbia and Puerto Rico) to review and update the Census Bureau’s residential address list for their jurisdiction. The Census Bureau relies on a complete and accurate address list to reach every living quarters and associated population for inclusion in the census.

The Census Address List Improvement Act of 1994 (Public Law 103-430) authorizes the LUCA operation.

In accordance with the law, the LUCA Feedback Phase provides participating governments with detailed feedback materials that document which local address updates the Census Bureau processed. LUCA participants may dispute the processing results of certain addresses, only if those addresses meet certain eligibility criteria.
