Burlington spans the Philadelphia exurbs to the Pine Barrens, and its growing suburban collar has steadily widened the Democratic presidential margin — reaching 16.6 points in 2024 despite a traditionally mixed political heritage.
The Democratic margin in Burlington County reached its widest at thirty points in 1964. The margin in 2024 was seventeen points — still decisive.
Burlington County's loyalty is rooted in its place. Median household income of $108,111, a 64% non-Hispanic-white share, and a population of 467,805 together describe a community whose political habits are deeply settled. The county's voting pattern over the last decade is most similar to that of Delaware County and Ulster County.
