The U.S. Census Bureau has launched a new, interactive map  that conveniently and easily displays local-level 2010 Census population counts . The application allows users to compare county-level population change from 1960 to 2010, as well as state-level data on race and Hispanic or Latino origin for 2010.
Last week, the rollout of detailed data began with the release of local population counts for Louisiana, Mississippi, New Jersey and Virginia. This week, local data for Arkansas, Indiana, Iowa, Maryland and Vermont are being released. For each state, the Census provides summaries of population totals as well as data on race, Hispanic origin, and voting age for multiple geographies within the state, such as census blocks, tracts, voting districts, cities, counties and school districts. The counts are being delivered on a state-by-state basis, and all states will receive their data by April 1.
As new data is released, the Census Bureau will update the map. Learn more about your state .
