Beaver County's sparse ranching communities and tiny population of roughly 6,000 produce some of the most concentrated Republican presidential margins in Utah, with the 2024 result exceeding 74 points.
The Democratic margin in Beaver County peaked at sixty-eight points in 1896. By 1968 the county had flipped, voting Republican for the first time in many years. The 2024 margin was seventy-four points, the most Republican-leaning result in the county's modern history.
The economic context is the key. Beaver County's median household income of $79,360 sits well below state and national norms, and 7% of residents live below the federal poverty line. The shift here is part of a broader realignment of working-class places across the country. The county's voting pattern over the last decade is most similar to that of Borden County and Gaines County.
