What it’s like

The place. Twin Oaks is a very small village in St. Louis County, with a population far smaller than most towns. People here tend to be older than in many places, and a four-year degree is common among adults. Poverty is rare, and homes sit at a middling price for the region. Winters are cold, with highs hovering around freezing in January and some snow most years. Summers are hot, and rain and melted snow fall steadily across the year.

Work. Residents mostly work in schools, hospitals and social care, in professional and business services, in banks, insurance and property, and in shops. Across St. Louis County, some of the largest workplaces are Washington University in St Louis, The Boeing Company and Mercy Hospital - St. Louis. A good number of people work from home, and the typical commute is a moderate one.

Things to do. The nearest outing on the list is World Wide Technology Soccer Park, a stadium a short drive away. Farther afield, a longer drive brings you to the Missouri Botanical Garden, a botanical garden, and to Gateway Arch National Park, a national park. The Saint Louis Art Museum, also a longer drive away, is another option for a day out.

FEMA’s National Risk Index (December 2025) rates the risk each natural hazard poses to the people, buildings and farms in Twin Oaks’ 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. Louis County and the St. Louis, MO-IL metro.
