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.

Madison County's 2024 presidential margin of R+45.3 reflects a pattern common to Montana's sparsely populated ranching counties, where Republican candidates have dominated by wide margins across successive election cycles.
Across the recorded series it reached a Democratic high of 67.3 points in 1896 and a Republican high of 52.1 points in 1984. Between 2020 and 2024 the county moved 5.5 points toward the Republican candidate; the 2024 margin was 45.3 points.
A population of 9,223, a 90% non-Hispanic-white share, and a median household income of $75,250 describe the county. The county's voting pattern over the last decade is most similar to that of Granite County and Carbon County.
