Deschutes anchors Oregon's outdoor-recreation economy around Bend, and its rapid in-migration of remote workers and retirees has flipped a once reliably Republican county to a consistent Democratic lean by double digits.
The Democratic margin in Deschutes County has rarely exceeded fifty-one points in modern history; the Republican margin has rarely exceeded thirty points. 2024 delivered the county to the Democratic candidate by ten points.
Deschutes County's demographics resemble the country more than they resemble most counties. A 87% non-Hispanic-white share, a 9% poverty rate, and a median household income of $92,758 — all within the broad national range. The county's voting pattern over the last decade is most similar to that of Chaffee County and Hays County.
