Chatham County, anchored by Savannah, delivers some of Georgia's widest Democratic margins on the coast, driven by a majority-minority population and a dense historic urban core that consistently outpaces statewide trends.
The Democratic margin in Chatham County reached its widest at seventy-eight points in 1912. The margin in 2024 was eighteen points — still decisive.
Chatham County's loyalty is rooted in its place. Median household income of $71,097, a 47% non-Hispanic-white share, and a population of 300,879 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 Mecklenburg County and Franklin County.
