Home to Moab and the gateway to Arches and Canyonlands, Grand County draws an unusually high share of outdoor-recreation workers and transplants, producing a consistent Democratic lean that stands out sharply against Utah's statewide Republican margins.
The Democratic margin in Grand County has rarely exceeded eighty-one points in modern history; the Republican margin has rarely exceeded fifty-two points. 2024 delivered the county to the Democratic candidate by nine points.
Grand County's demographics resemble the country more than they resemble most counties. A 84% non-Hispanic-white share, a 13% poverty rate, and a median household income of $67,106 — all within the broad national range. The county's voting pattern over the last decade is most similar to that of Leelanau County and Nevada County.
