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.

Miami County, anchored by the small city of Peru, delivers lopsided Republican margins in nearly every cycle — its 2024 presidential result of R+54.5 reflects a broader shift toward single-party dominance across rural north-central Indiana.
Across the recorded series it reached a Democratic high of 25.9 points in 1912 and a Republican high of 54.5 points in 2024. Between 2020 and 2024 the county moved 1.4 points toward the Republican candidate; the 2024 margin was 54.5 points.
A population of 35,712, a 87% non-Hispanic-white share, and a median household income of $61,139 describe the county. The county's voting pattern over the last decade is most similar to that of Fulton County and Carroll 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.
