Each row is a county-allocated estimate of U.S. House votes for this district — county returns apportioned onto its boundary, not precinct-counted. “Vote lead” is the estimated local lead here, not necessarily the winner of the full contest.
With a 2024 presidential margin of D+85.6, this Philadelphia-area district ranks among the most lopsided in the state, reflecting a dense, heavily Democratic urban core where Republican competitiveness is effectively absent.
Across the recorded series it reached a Democratic high of 93.2 points in 2012. Between 2020 and 2024 the district moved 4.7 points toward the Republican candidate; the 2024 margin was 85.7 points.
A population of 62,188, a 4% non-Hispanic-white share, and a median household income of $40,244 describe the district. The district's voting pattern over the last decade is most similar to that of State House District 201 and State House District 190.
