U.S. House
Each result reflects the U.S. House district as it was drawn for that election; redistricting has redrawn these lines over time, so they can differ from the current 120th-Congress district shown on the map above.
Ohio's 4th covers a swath of north-central and west-central farm country where Republican presidential nominees have carried the district by margins exceeding 35 points in recent cycles, reflecting a rural electorate with few competitive precincts.
Across the recorded series it reached a Democratic high of 15.5 points in 1912 and a Republican high of 42.6 points in 2024. Between 2020 and 2024 the district moved 2.2 points toward the Republican candidate; the 2024 margin was 42.6 points.
A population of 786,513, a 86% non-Hispanic-white share, and a median household income of $77,081 describe the district. The district's voting pattern over the last decade is most similar to that of Congressional District 12 and Congressional District 2.
The congressional districts 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.
