Local Update of Census Addresses (LUCA)

LUCA is the only opportunity offered to local governments to review the Census Bureau's residential address list.


Local government leaders:
Make sure your community gets its fair share of funding in the decade ahead!

Before 2020 Census forms appear in mailboxes, the U.S. Census Bureau needs addresses. If the Bureau doesn’t know that a new subdivision or apartment building has sprung up, residents could go uncounted. That would mean less federal and state funding for your community. And, because the decennial census is the base of your community's estimated population until the next census, a poor count in 2020 will affect your estimate for the next 10 years.

In July 2017, the Census invited local governments to register to help verify and update a database of all residential addresses through its Local Update of Census Addresses (LUCA) program. Counties, cities, townships, and tribal governments will be asked to review the Census Bureau’s address file for accuracy, and supplement it with new or overlooked addresses. This review began in early 2018.

Below are a series of training videos to help you understand and begin to prepare for LUCA. The videos are taken from a recent webinar organized by the Census Bureau’s State Data Center Network. The Census Bureau will be offering formal trainings for all registered participants beginning in January. Once a training schedule is announced, it will be posted here.
