State, Local, and Tribal Governments Can Update 2010 Address Lists
The 1994 Census Address List Improvement Act allows local, state and tribal governments to review the addresses for their areas in the Master Address File the Census Bureau uses to administer the decennial census. Liaisons, who are subject to the same confidentiality requirements as census workers, receive address lists, maps, and address tallies and submit revisions to the Census Bureau.
A new Census Bureau web page provides an overview of this program known as the Local Update of Census Addresses (LUCA), spells out the options for review, and explains how 2010 will differ from 2000 in this regard. It also provides a calendar showing milestone dates. LUCA means governments can help the Census Bureau attain a more accurate and complete census.
