What it’s like
The place. Sullivan is a small city in Franklin County, Missouri, where most homes are lived in by their owners. Household incomes run below the county's, and typical home values are modest. A four-year degree is held by fewer adults than is common across the country, and the town's residents are close to the middle of the age range. Winters are cold, with a fair amount of snow, and summers are hot, with plenty of rain and melted snow through the year.
Work. Residents work mostly in schools, hospitals and social care, with manufacturing, the building trades and retail close behind. The largest workplaces in Sullivan include KDC-One, an aerosol can filler that works on contract, Walmart, and Missouri Baptist Sullivan Hospital. Most people drive to work, the typical commute is a moderate one, and few work from home.
Things to do. Meramec Caverns, a well-known tourist attraction, is a short drive away. Meramec State Park and the Meramec Conservation Area are both protected areas within a short drive, for walking and time outdoors. Onondaga Cave State Park is a longer drive away and is another protected area to visit.

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 Franklin County and the St. Louis, MO-IL metro.
