Darlington County's rural Pee Dee economy, long anchored by tobacco and textile industries, has shifted its presidential margins rightward by double digits over two decades, even as its population holds a substantial Black voting-age share above 40%.
The Democratic margin in Darlington County has rarely exceeded 100 points in modern history; the Republican margin has rarely exceeded forty-five points. 2024 delivered the county to the Republican candidate by thirteen points.
Darlington County's demographics resemble the country more than they resemble most counties. A 54% non-Hispanic-white share, a 21% poverty rate, and a median household income of $48,581 — all within the broad national range. The county's voting pattern over the last decade is most similar to that of Chickasaw County and Hidalgo County.
