What it’s like
The place. Carterville is a small city where most homes are lived in by their owners, and incomes run a little below the county's. Typical home values and rents sit in a moderate range, and a good share of adults hold a four-year degree. Winters are cold, with some snow, and summers turn hot, with plenty of rain and melted snow through the year.
Work. Residents work mostly in schools, hospitals and social care, with shops, banks and insurance, and manufacturing also employing many. Across Williamson County, some of the largest workplaces are Aisin MFG. Illinois, which makes sunroofs and automotive parts, the Veterans Health Administration, and Herrin Hospital. Unemployment across the county has eased over the past year, and the county has added jobs, so the picture looks steady. Most people have a fairly short drive to work, and some work from home.
Things to do. Crab Orchard Lake, a reservoir in or beside town, is the nearest place for time on the water. A short drive away are Crab Orchard National Wildlife Refuge, a protected area good for walking and watching birds, and Little Grassy Lake. For a longer day out, Shawnee National Forest is a larger protected area a longer drive away.

FEMA’s National Risk Index (December 2025) rates the risk each natural hazard poses to the people, buildings and farms in Carterville’s census tracts, against the rest of the country; all of them together, relatively high. 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 Williamson County and the Carbondale-Marion, IL metro.
