What it’s like
The place. Dennison is a town in Illinois, within Clark County. Its residents are older on average than people across the country, and a larger share of them own the homes they live in. Winters here are cold, summers are warm, and rain and melted snow fall steadily through the year.
Work. Many residents work in schools, hospitals and social care, or in manufacturing, the building trades and retail shops. Unemployment is lower than it was a year earlier, though the county has somewhat fewer jobs than the year before. A smaller share of adults hold a four-year degree than across the country as a whole, and few people work from home.
Things to do. The CANDLES Holocaust Museum and Education Center and the Swope Art Museum are both a short drive away and are among the better-known places to visit nearby. For time outdoors, Shakamak State Park is a longer drive away and is a protected area of woods and water.

Natural hazards
- DroughtRelatively moderate
FEMA’s National Risk Index (December 2025) rates the risk each natural hazard poses to the people, buildings and farms across Clark County, against the rest of the country; all of them together, very low. 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 Clark County.
