What it’s like
The place. Hardin is a small village and the seat of Calhoun County, in the river country of western Illinois. The people who live here are older than in most of the country, and household incomes run a little below the county's. Winters are cold, with snow that comes and goes, and summers turn properly hot; rain and melted snow fall through the year.
Work. Many residents work in schools, hospitals and social care, with farming, shops and the building trades also employing local people. Across Calhoun County, the biggest workplaces are the school districts, among them Calhoun CUSD 40 and Brussels CUSD 42. Fewer adults here hold a four-year degree than in much of the country, and the number of jobs across the county has held close to steady.
Things to do. Macoupin Creek runs in or beside town, and Two Rivers National Wildlife Refuge, a protected area, is a short drive away. Also a short drive off is the Koster Site, an archaeological site. For a longer outing, Pere Marquette State Park is 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 Hardin’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 Calhoun County and the St. Louis, MO-IL metro.
