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.
PA-16 spans the counties south and west of Pittsburgh, where a working-class electorate has shifted decisively toward Republican candidates over the past decade, delivering a 23-point presidential margin in 2024.
Across the recorded series it reached a Democratic high of 30.9 points in 1964 and a Republican high of 50.8 points in 1924. Between 2020 and 2024 the district moved 2.1 points toward the Republican candidate; the 2024 margin was 22.8 points.
A population of 764,852, a 87% non-Hispanic-white share, and a median household income of $67,764 describe the district. The district's voting pattern over the last decade is most similar to that of Congressional District 14 and Congressional District 9.
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.
