Flagler's population nearly doubled between 2000 and 2020, driven largely by retirees settling in planned communities like Palm Coast. That demographic influx has accompanied a consistent rightward trend in presidential margins, reaching R+28.2 in 2024.
The Republican margin in Flagler County reached its widest at forty-eight points in 1972. The margin in 2024 was twenty-eight points, in line with the county's deep historical pattern.
Flagler County's loyalty is rooted in its place. Median household income of $77,363, a 75% non-Hispanic-white share, and a population of 126,528 together describe a community whose political habits are deeply settled. The county's voting pattern over the last decade is most similar to that of St. Clair County and Clark County.
