The U.S. Census Bureau announced this week that 2010 Census population totals and demographic characteristics have been released for communities in all 50 states, the District of Columbia and Puerto Rico  – ahead of the April 1 deadline. The data have provided the first look at population counts for small areas and race, Hispanic origin, voting age and housing unit data released from the 2010 Census. With the release of data for all states, national-level counts of these characteristics are now available.
In April, the Census Bureau will release the National Summary File of Redistricting Data, providing the same population, housing unit counts and demographic characteristics for the United States and other cross-state geographies, such as regions, divisions, metropolitan areas and American Indian, Alaska Native and Native Hawaiian areas.
Census data are now being used by state officials to realign congressional and state legislative districts in their states, taking into account population shifts over the last decade.
