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.

Brown County's rural, sparsely populated landscape has produced some of the widest presidential margins in the state, with fewer than 7,000 residents concentrated in small towns and farmland along the Illinois River bluffs.
Across the recorded series it reached a Democratic high of 42.3 points in 1912 and a Republican high of 59.9 points in 2024. Between 2020 and 2024 the county moved 2.7 points toward the Republican candidate; the 2024 margin was 59.9 points.
A population of 6,322, a 74% 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 Pershing County and Gilmer 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.
