Advanced notice send out to Highest Elected Officials and other LUCA contacts.
In addition to the Advance Notice Letter, the LUCA information booklet, promotional
participant workbooks and instructor guides, the Census Bureau will provide tools for
potential LUCA partners at the Advance Notice stage. These tools will include an
Address Count List for each GU, as well as a public geocoding tool. Potential LUCA
partners can load their own residential address list into the Census Bureau’s geocoding
tool to generate a count of residential addresses by block and compare it to the Census
Bureau’s count of residential addresses by block. This will allow potential LUCA
partners to see where the Census Bureau’s residential address count differs from their
own and to assess their need to participate in the LUCA Operation. Address Count List are now availale at the Census Bureau LUCA web site
