2020 Local Update of Census Addresses (LUCA)

Preparation for the 2020 Census begins with LUCA. LUCA is the only opportunity offered to state, local, and tribal governments to review and comment on the U.S. Census Bureau's residential address list prior to the 2020 Census. 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.
