Census forms are sent to housing units, not to people; thus, Census 2010 won't be accurate if the Census Bureau doesn't know about all the housing units in an area. Despite their best efforts, there is no way the Census Bureau can replicate the knowledge local governments possess about their communities.
The LUCA program provides the opportunity for local officials to review the addresses used by the Census Bureau in order to ensure an accurate census. A large number of Indiana's cities, towns and counties participated in this technical program. They will be receiving feedback from the Census Bureau in Fall 2009.
