What it’s like
The place. Weldon Spring is a city in St. Charles County, Missouri, where nearly all homes are lived in by their owners and very few households live below the poverty line. Incomes run well above the county's, and typical home values are high. Most adults hold a four-year degree. Winters are cold, with January highs a little above freezing and lows well below it, and some snow falls each year. Summers are hot, and rain and melted snow add up to a fair amount over the year.
Work. Residents work mostly in schools, hospitals and social care, with many also in banks, insurance and property, in manufacturing, and in restaurants, hotels and entertainment. Among the largest workplaces in Weldon Spring are Distribution Management Inc. HQ, a wholesaler of cartridge toner, and Centerpointe Hospital, a psychiatric hospital. Unemployment across St. Charles County is a little lower than it was a year ago. The typical commute is a moderate one, and a good number of people work from home.
Things to do. The Butterfly House at the Missouri Botanical Garden is a short drive away, a good outing for a quiet afternoon. A longer drive takes you to Gateway Arch National Park, one of the best known landmarks in the region. The Saint Louis Zoo is also 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 Weldon Spring’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 St. Charles County and the St. Louis, MO-IL metro.
