Home to Birmingham and a majority-Black electorate, Jefferson County delivered a 10-point Democratic margin in 2024 — a striking outlier in a state that went Republican statewide by nearly 30 points.
The county's recent history is a story of close margins. The Democratic margin reached eighty points in 1936; the Republican margin reached seventy-three points in 1964. Most other elections have been decided by single-digit points.
Jefferson County's demographics — a population of 667,755, a 48% non-Hispanic-white share, a median household income of $66,388 — situate the county close to national averages on several dimensions.
