Government Redistricting Web Sites
The decennial population Census of the United States is constitutionally required for determining congressional representation. After each decennial census, the Census Bureau assigns each state the number of seats it will have in the U.S. House of Representatives for the next ten years. Individual states are given the responsibility of drawing legislative boundaries for congressional districts as well as for state legislative districts. In some states, this process is done by the state legislature and in other states it is done by independent commissions. This process will occurr again following the 2011 release of state population data from the 2010 Census.
