What it’s like
The place. Johnston is a small town in Edgefield County, South Carolina, where people tend to know one another. Homes here are priced well below what is typical for the country, and fewer adults hold a four-year degree than in most places. Winters are mild and short, with almost no snow, and summers run hot, with plenty of rain through the year.
Work. Most residents work in schools, hospitals and social care, with manufacturing, shops and the building trades close behind. Across Edgefield County, the largest workplaces include Edgefield 01 Schools, Bridgestone Americas and the South Carolina Growers Association, which reflects both the county's schools and its factory and peach-farming roots. Commutes are on the longer side, and very few people work from home.
Things to do. For time outdoors, Lake Strom Thurmond is a large reservoir and Lake Greenwood is another lake, both a longer drive away. History lovers can head to Ninety Six National Historic Site, a protected area, also a longer drive away. The Morris Museum of Art is a museum for a rainy day, likewise a longer drive from town.

FEMA’s National Risk Index (December 2025) rates the risk each natural hazard poses to the people, buildings and farms in Johnston’s census tracts, against the rest of the country; all of them together, relatively moderate. It is meant for planning, not a substitute for a local risk assessment or a flood map: FEMA’s index.
From the U.S. Census Bureau’s 2020 census and its American Community Survey (2020–2024 five-year estimates), and the Bureau of Labor Statistics. A survey, so each figure has a margin of error, and figures it is not sure of are left out. More on Edgefield County and the Augusta-Richmond County, GA-SC metro.
