What it’s like
The place. Barnhart is a community in Jefferson County, Missouri, with a younger population than the typical American town and incomes above the county's. Nearly all homes are lived in by their owners, and relatively few residents live below the poverty line. Winters are cold, with some snow, and summers are warm, with a fair amount of rain through the year.
Work. Many residents work in schools, hospitals and social care, and others work in manufacturing, the building trades, and professional and business services. Some of the largest workplaces across Jefferson County are FOX C Schools, Mercy Hospital Jefferson and Jefferson College. Most people commute to their jobs, and few work from home.
Things to do. The Meramec River is a short drive away and suits an afternoon by the water. A longer drive leads into St. Louis, where the Gateway Arch National Park, the Saint Louis Zoo and the Missouri Botanical Garden are among the best known places to visit.

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