OFFICE OF THE DIRECTOR

FROM THE ASSOCIATE DIRECTOR FOR
DECENNIAL CENSUS PROGRAMS
In July 2017, the U.S. Census Bureau invited your state to participate in the 2020 Census Local
Update of Census Addresses Operation (LUCA), as mandated by the Census Address List
Improvement Act of 1994 (Public Law 103-430). As of this date, we have not received your response.
If you have responded, please disregard this letter.
This is the only opportunity offered to your state to review and update the 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. Participation in
LUCA can help ensure an accurate count for your state.
Enclosed with this letter are:
