Inyo spans 10,000 square miles but holds fewer than 18,000 residents, and disputes over federal land management and water rights to Los Angeles consistently define its electoral and policy debates.
The county's recent history is a story of close margins. The Democratic margin reached fifty points in 1912; the Republican margin reached forty-two points in 1984. Most other elections have been decided by single-digit points.
Inyo County's demographics — a population of 18,739, a 62% non-Hispanic-white share, a median household income of $73,991 — 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 Delaware County and Talbot County.
