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.
Illinois's 10th Congressional District stretches along the northern Lake Michigan suburbs, blending dense lakefront communities with inner-ring towns that have shifted steadily toward Democratic presidential candidates over the past two decades.
Across the recorded series it reached a Democratic high of 25.7 points in 2020 and a Republican high of 64.5 points in 1920. Between 2020 and 2024 the district moved 3.8 points toward the Republican candidate; the 2024 margin was 21.9 points.
A population of 753,714, a 58% non-Hispanic-white share, and a median household income of $107,371 describe the district. The district's voting pattern over the last decade is most similar to that of Congressional District 11 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.
