St. Francis County sits in the Arkansas Delta, where a majority-Black population and persistent rural poverty produce one of the state's rare competitive margins — the 2024 presidential race landed within a single percentage point.
The county's recent history is a story of close margins. The Democratic margin reached eighty-eight points in 1932; the Republican margin reached thirty-five points in 1972. Most other elections have been decided by single-digit points.
St. Francis County's demographics — a population of 22,400, a 41% non-Hispanic-white share, a median household income of $42,574 — situate the county close to national averages on several dimensions. The county's voting pattern over the last decade is most similar to that of Chicot County and Lee County.
