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.

Morgan County's rural, agricultural character has tracked a steady rightward shift over the past two decades, with its county seat of Jacksonville providing a small urban anchor that no longer offsets the broader regional realignment.
Across the recorded series it reached a Democratic high of 28.8 points in 1912 and a Republican high of 33.1 points in 1984. Between 2020 and 2024 the county moved 0.6 points toward the Republican candidate; the 2024 margin was 32.4 points.
A population of 33,021, a 87% non-Hispanic-white share, and a median household income of $66,306 describe the county. The county's voting pattern over the last decade is most similar to that of Madison County and Wayne 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.
