Sioux City anchors a rare three-state metropolitan area, drawing its electorate from counties in Iowa, Nebraska, and South Dakota whose agricultural economies and meatpacking workforce produce distinctive voting patterns compared with each state's urban cores.
Across the recorded series it reached a Democratic high of 36.8 points in 1932 and a Republican high of 41.2 points in 1904. Between 2020 and 2024 the metro moved 7.6 points toward the Republican candidate; the 2024 margin was 26.3 points.
A population of 144,682, a 66% non-Hispanic-white share, and a median household income of $75,053 describe the metro. The metro's voting pattern over the last decade is most similar to that of Austin, MN and Marshalltown, IA.
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.
