OFFICE OF THE DIRECTOR

FROM THE ASSOCIATE DIRECTOR FOR
DECENNIAL CENSUS PROGRAMS
In July 2017, the U.S. Census Bureau invited your government 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 government 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 jurisdiction.
Enclosed with this letter are:
