What it’s like

The place. Rockville is a very small city in St. Clair County, Missouri, with a quiet, rural feel. Homes here are typically valued well below what buyers pay in much of the country. Winters are cold, with highs that stay near freezing in January and a modest amount of snow, while summers turn hot by July, and rain and melted snow add up to a fair amount over the year.

Work. Across St. Clair County, household incomes sit below the national picture, and the job market has been growing slightly, with unemployment easing over the past year. Many residents work in schools, hospitals and social care, in shops, in the building trades, or in transport, warehouses and utilities. Some of the county's largest workplaces are Truman Lake Manor, Osceola Schools and Ellett Memorial Hospital.

Things to do. Panther Creek runs in or beside town, and the Marais des Cygnes River and Little Osage River are both a short drive away for a day by the water. Also a short drive off is Fort Carondelet, a historic fort that points back to the area's early past.

FEMA’s National Risk Index (December 2025) rates the risk each natural hazard poses to the people, buildings and farms in Rockville’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 Kansas City, MO-KS metro.
