Stretching 1,200 miles into the Pacific, Aleutians West is among the most geographically isolated counties in the U.S., yet its mixed Alaska Native and military-connected population has produced near-even presidential margins in recent cycles.
The county's recent history is a story of close margins. The Democratic margin reached seventy-eight points in 1964; the Republican margin reached thirty-five points in 1988. Most other elections have been decided by single-digit points.
Aleutians West Census Area's demographics — a population of 5,235, a 24% non-Hispanic-white share, a median household income of $135,500 — situate the county close to national averages on several dimensions. The county's voting pattern over the last decade is most similar to that of Nome Census Area and Dillingham Census Area.
