How are Districts determined?
Every 10 years, following the national census, the boundaries of the legislative (and Congressional) districts are adjusted to make the districts as evenly split among the population as possible. This is referred to as Redistricting for the Congressional districts or Reapportionment for the Legislative districts. Congressional Redistricting is handled by legislation, and Legislative Reappotionment are handled by a Legislative Reapportionment Commission whose members are appointed by the leadership of the General Assembly, the Governor, and the Chief Justice of the Colorado Supreme Court. In the event the Legislature and the Governor fail to enact redistricting legislation, the courts will generally order a plan to be adopted.
