Yazoo County sits at the eastern edge of the Mississippi Delta, where a majority-Black population and a historically agriculture-dependent economy produce one of the state's most competitive presidential margins, with 2024's R+2.4 result among Mississippi's closest.
The county's recent history is a story of close margins. The Democratic margin reached ninety-eight points in 1936; the Republican margin reached ninety-two points in 1964. Most other elections have been decided by single-digit points.
Yazoo County's demographics — a population of 24,835, a 40% non-Hispanic-white share, a median household income of $39,295 — 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 Kusilvak Census Area and San Joaquin County.
