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.
District 112 sits in the competitive tier of Pennsylvania's lower chamber, where a 1.1-point Democratic presidential lean in 2024 signals an electorate that swings with candidate quality and turnout rather than locking in with either party.
Across the recorded series it reached a Democratic high of 46.8 points in 1964 and a Republican high of 34.3 points in 1924. Between 2020 and 2024 the district moved 5.6 points toward the Republican candidate; the 2024 margin was 1.1 points.
A population of 62,663, a 89% non-Hispanic-white share, and a median household income of $65,874 describe the district. The district's voting pattern over the last decade is most similar to that of State House District 118 and State House District 114.

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.
