Every 10 years, states redraw the boundaries of their congressional districts to reflect new population counts from the census. Colorado gained a seat this cycle after the 2020 census. The state’s independent redistricting commission created a map that adds a new competitive seat in the northern suburbs of Denver and makes the 7th District, currently held by retiring Democratic Rep. Ed Perlmutter, less secure for his party.

How the new map shifts voting power by demographic

Colorado gains a seat thanks to population growth recorded in the 2020 census. White voters represent the majority in all eight of its districts.

Methodology note: Vote margins for new congressional districts are determined by calculating precinct-level vote totals for each district. If a new district splits a precinct, block-level voting-age population is used to allocate that precinct’s votes to the new districts. Block-level demographic data from the 2020 census is reaggregated into each new district’s boundaries.
