Spanning roughly 25,000 square miles with fewer than 3,000 residents, Copper River Census Area is one of Alaska's most sparsely populated jurisdictions, and its electorate has leaned heavily Republican in every recent presidential cycle.
The Republican margin in Copper River Census Area reached its widest at sixty-five points in 1984. The margin in 2024 was forty-three points, in line with the county's deep historical pattern.
Copper River Census Area's loyalty is rooted in its place. Median household income of $79,250, a 54% non-Hispanic-white share, and a population of 2,626 together describe a community whose political habits are deeply settled. The county's voting pattern over the last decade is most similar to that of Garfield County and Rockwall County.
