Yukon-Koyukuk is the largest county-equivalent in the United States, spanning over 145,000 square miles of interior Alaska, yet its small population—predominantly Alaska Native—has delivered consistent Democratic margins in recent presidential cycles.
The Democratic margin in Yukon-Koyukuk Census Area reached its widest at fifty-seven points in 1964. The margin in 2024 was twenty-one points — still decisive.
Yukon-Koyukuk Census Area's loyalty is rooted in its place. Median household income of $55,741, a 22% non-Hispanic-white share, and a population of 5,195 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 Nome Census Area and Bexar County.
