Straddling the Mississippi, the Quincy metro pairs a mid-sized Illinois city with rural Missouri counties, producing a reliably conservative regional tilt that has widened in presidential cycles over the past decade.
Across the recorded series it reached a Democratic high of 36.3 points in 1932 and a Republican high of 48.9 points in 2024. Between 2020 and 2024 the metro moved 1.3 points toward the Republican candidate; the 2024 margin was 48.9 points.
A population of 74,678, a 90% non-Hispanic-white share, and a median household income of $65,385 describe the metro. The metro's voting pattern over the last decade is most similar to that of Sidney, OH and Decatur, IN.
The metros 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.
