The St. Louis media market straddles the Missouri-Illinois border, blending a heavily Democratic city center with competitive suburban counties that have shifted markedly in both directions over the past three federal election cycles.
Across the recorded series it reached a Democratic high of 34.1 points in 1964 and a Republican high of 21.9 points in 1920. Between 2020 and 2024 the market moved 2.6 points toward the Republican candidate; the 2024 margin was 5.3 points.
A population of 3,190,471, a 73% non-Hispanic-white share, and a median household income of $79,136 describe the market. The market's voting pattern over the last decade is most similar to that of Detroit and Cleveland-Akron (Canton).
The media markets 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.
