Stretching across Prince William Sound and the Kenai Peninsula's fringes, Chugach Census Area is one of Alaska's least-dense jurisdictions, where Indigenous communities and remote fishing villages drive turnout patterns that diverge sharply from urban Alaska.
The Republican margin in Chugach Census Area reached its widest at forty-two points in 1984. The margin in 2024 was seventeen points, in line with the county's deep historical pattern.
Chugach Census Area's loyalty is rooted in its place. Median household income of $90,509, a 71% non-Hispanic-white share, and a population of 6,862 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 Kodiak Island Borough and Wrangell City and Borough.
