What it’s like
The place. Sullivan is a small city in Moultrie County where most homes are lived in by their owners, and where the typical home is worth less than in much of the country. Household incomes run below the county's, and relatively few adults hold a four-year degree. Winters are cold, with highs only a little above freezing in January and lows well below it, and some snow each year. Summers turn warm, and rain and melted snow add up to a fair amount over the year.
Work. Residents work mostly in schools, hospitals and social care, in manufacturing, in shops, and in transport, warehouses and utilities. Among the largest workplaces in Sullivan are Hydro-Gear, which makes hydrostatic drives, Agri-Fab, which makes lawn and garden equipment, and the Sullivan school district. Commutes are short, and very few people work from home. Unemployment in Moultrie County is lower than it was a year earlier, and the county has added a few jobs over the past year.
Things to do. Several parks and waterways are a short drive away, among them Wolf Creek State Park, the West Okaw River and Eagle Creek State Recreation Area. Farther afield, a longer drive brings you to Lake Shelbyville, a large reservoir, and to Robert Allerton Park, a botanical garden. The mix is mostly open water, woods and trails, suited to a day outdoors.

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