Southampton's population of roughly 17,000 is anchored by agriculture and timber, and its electorate has shifted toward wide Republican margins at the federal level even as local races occasionally remain competitive.
The shift began with civil rights. 2004 marked the realignment in Southampton County, by a eight points margin. The Republican margin reached its widest at sixty-six points in 1972. The 2024 margin was twenty-five points.
The political shift has tracked, in Southampton County, the political shift of the South more broadly. A 61% non-Hispanic-white share, a median household income of $70,795, and a 9% poverty rate describe the demographic context. The county's voting pattern over the last decade is most similar to that of Pasco County and Chowan County.
