What it’s like
The place. Round O is a community in Colleton County, South Carolina, which the Census does not count on its own, so the figures describe the wider county. Most homes are lived in by their owners, and the county's population is mostly working-age and older adults. Winters are mild with little or no snow, summers are hot, and rain falls heavily through the year.
Work. Schools, hospitals and social care, manufacturing, the building trades and retail shops employ many of the county's residents. Jobs in the county were fewer over the most recent year, though unemployment has eased compared with a year earlier. Few adults hold a university degree, most people drive a fair distance to work, and few work from home.
Things to do. Four Hole Swamp and the Edisto River are both rivers a longer drive away, suited to those who enjoy time on the water. Colleton State Park is a protected area also a longer drive away, offering open land for a day outdoors. Angel Oak, a protected area a longer drive away, is one of the best known live oaks in the South.

FEMA’s National Risk Index (December 2025) rates the risk each natural hazard poses to the people, buildings and farms across Colleton County, 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 Colleton County.
