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 (for example, INDIANA) and in other states it is done by independent commissions. This process occured following the 2011 release of state population data from the 2010 Census. It will occur again in 2021 following release of 2020 decennial census population data. The COVID-19 pandemic has delayed collecting and release of Census data including redistricting data which is now targeted to be delivered to states. between July 1-September 30, 2020
