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 Bureau will invite 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, and townships will be asked to review the Census Bureau’s address file, check it for accuracy, and supplement the file with new or overlooked addresses. This review will begin in early 2018.

What do you need to do?

Just look for the Census Bureau’s LUCA invitation in July 2017. The Bureau will mail packets to the highest elected official of your county, city, township, or American Indian reservation and send a copy to any additional contacts it has on file. You can help by making sure that that packet doesn’t get accidentally overlooked. LUCA registrations must be returned to the Census Bureau by December 15, 2017. 

• After you register you can prepare by:  
          - Developing a strategy for your government's address review  
          - Identifying local address sources such as new building permits, planning and zoning records, and utility and property tax records
          - Attend LUCA promotional and technical webinars and workshops in Fall 2017

You can learn more about LUCA at the U.S. Census Bureau's website. Still have questions? Please send us an email:
