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.
New Jersey's 10th anchors its identity in Essex and Hudson County urban cores, where Democratic presidential margins have exceeded 50 points in recent cycles, making it among the least competitive House seats in the country.
Across the recorded series it reached a Democratic high of 65.5 points in 2012 and a Republican high of 11.7 points in 1920. Between 2020 and 2024 the district moved 11.1 points toward the Republican candidate; the 2024 margin was 50.9 points.
A population of 773,965, a 19% non-Hispanic-white share, and a median household income of $72,784 describe the district. The district's voting pattern over the last decade is most similar to that of Congressional District 9 and Congressional District 8.
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.
