Once a reliably Republican collar county, Montgomery has shifted so decisively that its 2024 presidential margin of D+22.8 now ranks among the widest in Pennsylvania, driven by high educational attainment and rapid demographic change in townships like Lower Merion.
Across the recorded series it reached a Democratic high of 26.3 points in 2020 and a Republican high of 57.0 points in 1924. Between 2020 and 2024 the county moved 3.5 points toward the Republican candidate; the 2024 margin was 22.8 points.
A population of 867,573, a 72% non-Hispanic-white share, and a median household income of $113,915 describe the county. The county's voting pattern over the last decade is most similar to that of Delaware County and Greater Bridgeport Planning Region.
