What it’s like

The place. Round Lake is a village in Lake County, Illinois, home to a good many people for a village of its kind. Households here earn slightly more than the county as a whole, and most homes are lived in by their owners rather than rented. Residents tend to be somewhat younger than in many towns, and a good share of adults hold a four-year degree.

Work. Residents work mainly in manufacturing, professional and business services, schools and hospitals, and banking, insurance and property. Among the largest workplaces in the village itself are the Round Lake school district, the Round Lake Area Park District and the Village of Round Lake. Commutes tend to be long, and a fair number of people work from home.

Things to do. Wooster Lake sits in or beside town, and Six Flags Great America, an amusement park, is a short drive away. The Chicago Botanic Garden is a longer drive, as is Geneva Lake. Winters are cold and snowy, with January the coldest month, and summers turn warm in July, with a fair amount of rain and melted snow through the year.

Natural hazards

  1. Cold wavesRelatively high
  2. TornadoesRelatively high
  3. Strong windRelatively high
  4. Inland floodingRelatively high
  5. LightningRelatively moderate

FEMA’s National Risk Index (December 2025) rates the risk each natural hazard poses to the people, buildings and farms in Round Lake’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 Lake County and the Chicago-Naperville-Elgin, IL-IN-WI metro.
