Barbour County sits in Alabama's Black Belt region, where a majority-Black population and a legacy of competitive statewide races once made it a notable swing point; the 2024 presidential margin of R+14.7 reflects a broader realignment across the region.
The Democratic margin in Barbour County has rarely exceeded ninety-five points in modern history; the Republican margin has rarely exceeded eighty points. 2024 delivered the county to the Republican candidate by fifteen points.
Barbour County's demographics resemble the country more than they resemble most counties. A 44% non-Hispanic-white share, a 21% poverty rate, and a median household income of $46,042 — all within the broad national range. The county's voting pattern over the last decade is most similar to that of Somerset County and Chickasaw County.
