Pitkin County, anchored by the resort city of Aspen, combines a small permanent population with high incomes and strong college-educated majorities — a profile that has pushed its presidential margins well above 40 points Democratic in recent cycles.
The Democratic margin in Pitkin County reached its widest at ninety-eight points in 1896. The margin in 2024 was forty-four points — still decisive.
Pitkin County's loyalty is rooted in its place. Median household income of $102,645, a 84% non-Hispanic-white share, and a population of 16,985 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 San Miguel County and Sonoma County.
