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.

Fall River County, anchored by Hot Springs near the Nebraska border, has delivered lopsided Republican presidential margins for decades. Its sparse, ranch-heavy landscape and small elderly population define an electorate with little demographic pressure toward competitive outcomes.
Across the recorded series it reached a Democratic high of 42.2 points in 1912 and a Republican high of 49.3 points in 2024. Between 2020 and 2024 the county moved 4.1 points toward the Republican candidate; the 2024 margin was 49.3 points.
A population of 7,258, a 84% non-Hispanic-white share, and a median household income of $67,917 describe the county. The county's voting pattern over the last decade is most similar to that of Custer County and Adams County.
The counties whose fingerprint — 2000–2024 trajectory, demographics, ancestry, religion — sits closest to this one, and why.
