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.
Indiana's 4th district spans the state's rural northwest and west-central corridor, where Republican presidential candidates have carried the district by 30 points or more in recent cycles, reflecting its predominantly small-town and agricultural character.
Across the recorded series it reached a Democratic high of 16.7 points in 1912 and a Republican high of 45.4 points in 1972. The 2024 margin was 29.3 points.
A population of 753,960, a 81% non-Hispanic-white share, and a median household income of $78,449 describe the district. The district's voting pattern over the last decade is most similar to that of Congressional District 6 and Congressional District 5.
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.
