Throughout the month of March, the U.S. Census Bureau will be releasing data from the 2010 Census. Check out the new interactive map which highlights the population gains and losses by state. This data will be used for redistricting and apportionment across the nation. By clicking on an individual state, you can see the apportionment trends over ttime. For example, a state, such as New York, which had 34 Congressional representatives in 1910 will lose 2 more seats as a result of this Census, leaving it with 27 representatives in the 113th Congress.
