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.

Rosebud County stretches across southeastern Montana's arid grasslands, blending ranching communities with a substantial Native American population — a demographic split that has historically produced varied turnout patterns even as countywide margins run heavily Republican.
Across the recorded series it reached a Democratic high of 28.4 points in 1936 and a Republican high of 53.6 points in 1904. Between 2020 and 2024 the county moved 3.0 points toward the Republican candidate; the 2024 margin was 37.1 points.
A population of 8,165, a 51% non-Hispanic-white share, and a median household income of $49,914 describe the county. The county's voting pattern over the last decade is most similar to that of Benson County and Glacier County.
