Redistricting

2020-2021

See also: Redistricting in Colorado after the 2020 census

On November 1, 2021, the Colorado Supreme Court approved the congressional redistricting plan that the state's Independent Congressional Redistricting Commission approved on September 28, 2021. Colorado was apportioned eight seats in the U.S. House of Representatives after the 2020 census, a net gain of one seat as compared to apportionment after the 2010 census. This map took effect for Colorado’s 2022 congressional elections.

The Denver Post's Alex Burness said that the approved map "gives comfortable advantages to each of Colorado’s seven incumbent members of Congress" and that the newly created 8th District would be competitive based on recent results.

How does redistricting in Colorado work? On November 6, 2018, Colorado voters approved two constitutional amendments, Amendment Y and Amendment Z, establishing separate non-politician commissions for congressional and state legislative redistricting. Each commission consists of four members belonging to the state's largest political party, four members belonging to the state's second-largest party, and four members belonging to no party. Commission members are appointed by a panel of three judges selected by the Chief Justice of the Colorado Supreme Court. The amendment requires at least eight of the commission's 12 members, including at least two members not belonging to any political party, to approve a map.

The Colorado Constitution requires that state legislative district boundaries "be contiguous, and that they be as compact as possible based on their total perimeter." In addition, "to the extent possible, districts must also preserve the integrity of counties, cities, towns and–where doing so does not conflict with other goals–communities of interest." There are no similar requirements for congressional districts.

This is the 7th Congressional District of Colorado after the 2001 redistricting process.
