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.

Yuma County sits at Arizona's southwestern corner along one of the busiest land-border crossings in the country, and its heavily Latino electorate has shifted markedly rightward over the past three presidential cycles, bucking earlier assumptions about demographic voting patterns.
Across the recorded series it reached a Democratic high of 53.3 points in 1936 and a Republican high of 36.1 points in 1984. Between 2020 and 2024 the county moved 14.2 points toward the Republican candidate; the 2024 margin was 20.4 points.
A population of 211,741, a 29% non-Hispanic-white share, and a median household income of $62,876 describe the county. The county's voting pattern over the last decade is most similar to that of Caldwell County and Yakima County.
The counties whose fingerprint — 2000–2024 trajectory, demographics, ancestry, religion — sits closest to this one, and why.
Twin score (0–100) = weighted cosine between tier-standardized fingerprints: presidential margins 2000–2024 with 12-yr trend and elasticity, ACS income, age, education, population and race, top reported ancestries, and religious adherence — chips name the closest-shared dimensions and the widest gap.
