Property tax · $270/mo 2.03% of value a year — the ACS 2020-2024 median bill over the median home value for Saint Clair County, IL

Insurance & upkeep · $171/mo insurance, maintenance and repairs together, from the BLS Consumer Expenditure Survey — the national figure for mortgaged homeowners, scaled to this market's home value. BLS publishes the three bundled and they cannot be split.

Both are priced off the same month's home value, so they rise with the market. Neither is a quote — a specific home's bill depends on its assessment, its age and its insurer.

What it’s like

The place. Belleville is a city where incomes run below the county's and a good share of residents live below the poverty line, though most homes are lived in by their owners. Typical home values and rents are modest, and residents are of an age close to that of the country as a whole. Winters are cold, with January highs staying well above freezing but lows dropping below it, and summers turn hot by July. Snow falls a little each year, and the town gets a fair amount of rain across the seasons.

Work. Many residents work in schools, hospitals and social care, with shops, professional and business services, and restaurants and hotels also employing a lot of people. Among the largest workplaces in Belleville are Memorial Hospital, Belleville Schools and Empire Comfort Systems. Unemployment has eased compared with a year ago, though St. Clair County has seen slightly fewer jobs than the year before. A four-year degree is held by a smaller share of adults than in many places, and the typical commute is of moderate length, with some people working from home.

Things to do. A longer drive brings you to some of the region's best known places. Gateway Arch National Park is a national park along the river, and Cahokia is an archaeological site that tells of the area's earliest cities. The Saint Louis Zoo is also a longer drive away, and it suits a day out with family.

FEMA’s National Risk Index (December 2025) rates the risk each natural hazard poses to the people, buildings and farms in Belleville’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.
