Migration is one input to a place’s political change, not its cause — a shift can also come from residents changing their minds, generational turnover, or turnout. These figures describe the places people moved between; they do not measure how any mover voted.

Bonneville delivered an R+45.6 margin in 2024, consistent with its pattern as a heavily LDS, exurban county centered on Idaho Falls — a regional hub whose growth has not meaningfully shifted its partisan composition.
Across the recorded series it reached a Democratic high of 41.4 points in 1936 and a Republican high of 66.2 points in 1984. Between 2020 and 2024 the county moved 1.8 points toward the Republican candidate; the 2024 margin was 45.4 points.
A population of 129,523, a 80% non-Hispanic-white share, and a median household income of $79,068 describe the county. The county's voting pattern over the last decade is most similar to that of Washington County and Utah County.
