What it’s like
The place. Dupo is a village in St. Clair County, just across the river from St. Louis. Household incomes here run below the county's, and homes are modestly priced. Winters are cold, with highs near freezing in January and a fair amount of snow, while July days turn hot.
Work. Residents work mostly in schools, hospitals and social care, with many others in professional and business services, shops, and restaurants and hotels. Among the larger workplaces in Dupo are Kuna Meat Company, the community unit school district and KFS Trucking. Most people travel a good distance to work, and few work from home.
Things to do. Much of what draws people out is a short drive away in and around St. Louis. Gateway Arch National Park is a national park on the riverfront, the Saint Louis Zoo is a zoo in Forest Park, and the Missouri Botanical Garden is a botanical garden. Cahokia, an archaeological site, is 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 Dupo’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 St. Clair County and the St. Louis, MO-IL metro.
