Duval County, anchored by Jacksonville, has shifted steadily toward competitive status as a growing Black electorate and an influx of younger, college-educated residents have eroded margins that once made it a reliable anchor of Florida's Republican coalition.
Across the recorded series it reached a Democratic high of 95.2 points in 1892 and a Republican high of 44.7 points in 1972. Between 2020 and 2024 the county moved 5.3 points toward the Republican candidate; the 2024 margin was 1.5 points.
A population of 1,023,153, a 48% non-Hispanic-white share, and a median household income of $71,277 describe the county. The county's voting pattern over the last decade is most similar to that of Stafford County and Warren County.
