Migration is one input to a place’s political change, not its cause — a shift can also come from residents changing their minds, generational turnover, or turnout. These figures describe the places people moved between; they do not measure how any mover voted.

Warren County's rural and small-town character sets it apart from New Jersey's densely populated corridors, and its R+20.7 margin in 2024 makes it one of the state's sharpest counterweights to the Democratic-leaning northeast.
Across the recorded series it reached a Democratic high of 38.5 points in 1912 and a Republican high of 46.6 points in 1928. Between 2020 and 2024 the county moved 4.3 points toward the Republican candidate; the 2024 margin was 20.7 points.
A population of 110,849, a 75% non-Hispanic-white share, and a median household income of $100,869 describe the county. The county's voting pattern over the last decade is most similar to that of Sussex County and Hunterdon County.
