2020 Census

The U.S. Census counts every resident in the United States. It is mandated by Article I, Section 2 of the Constitution and takes place every 10 years. The data collected by the decennial census determine the number of seats each state has in the U.S. House of Representatives and is also used to distribute billions in federal funds to local communities.

Local Update of Census Addresses (LUCA)

LUCA general information - Flyer and Guide.

An accurate population count starts with an up-to-date and complete address list. The LUCA program provides state, local and tribal governments with a once-in-a-decade opportunity to update the Census Bureau’s address list that is used to conduct the decennial census. State, local and tribal government participation in the 2020 LUCA program can contribute to a more accurate population count for their communities.

For more information about LUCA, please visit www.census.gov/geo/partnerships/luca.html (www.census.gov).

LUCA Informational Workshops

LUCA workshops were held in mid-2017 to provide an overview of the program, explain how it will benefit your community, and provide an opportunity to ask questions. The workshops also covered program goals, participation methods, and security guidelines.
