On December 21, 2010, the Commerce Department released 2010 Census population figures and the resulting reapportionment of seats in the House of Representatives. The apportionment population of the 50 states in 2010 is 309,183,463, a figure 9.9% greater than in 2000. Just as in the 108th Congress, 12 seats will shift among 18 states in the 113th Congress as a result of the reapportionment. The next census data release will begin February 2011, when the Census Bureau will provide states the small-area data necessary to re-draw congressional and state legislative districts in time for the 2012 elections.
