The Census Bureau has begun releasing local-level 2010 Census population counts, delivering the data on a state-by-state rolling basis through March. These data include official census population totals, as well as data on race, Hispanic or Latino origin and voting age for multiple geographies within each state.
The Census Bureau has launched an interactive map widget that showcases these data for each state, as well as Puerto Rico and the District of Columbia. The application enables users to view county-level population change from 1960 to 2010, as well as state level data on race and Hispanic or Latino origin.
The widget can be embedded on your website and will be updated as additional states are released.
American Fact Finder can be used to access data from multiple geographies within each state, including census blocks, tracts, voting districts, cities, counties and school districts.
