Martin County sits along the Roanoke River in eastern North Carolina, with a population that is roughly 40% Black — one of the higher shares in the state. That demographic mix has kept presidential margins closer here than in many surrounding rural counties.
The Democratic margin in Martin County has rarely exceeded ninety-six points in modern history; the Republican margin has rarely exceeded thirty-nine points. 2024 delivered the county to the Republican candidate by ten points.
Martin County's demographics resemble the country more than they resemble most counties. A 52% non-Hispanic-white share, a 20% poverty rate, and a median household income of $48,578 — all within the broad national range. The county's voting pattern over the last decade is most similar to that of Robeson County and Granville County.
