What it’s like

The place. Prospect Heights is a city in Cook County, in the northwest suburbs of Chicago. It is home to more people in their later years than younger ones, with a median age a bit older than you would find in many towns. Most homes are lived in by their owners, and household incomes run a little above the county's, with fewer residents living below the poverty line than you might expect in a place this close to a big city. Winters are cold, with January the coldest month, and summers turn warm in July, with a steady year-round mix of rain and melted snow.

Work. Residents work mainly in manufacturing, in schools, hospitals and social care, in professional and business services, and in shops. Among the largest workplaces in Prospect Heights are Costco Wholesale, the local school district and the packaging maker Plitek. Commutes are moderate, and a good number of residents work from home.

Things to do. The Chicago Botanic Garden is a botanical garden a short drive away. In the city itself, a longer drive away, you can visit the Art Institute of Chicago, one of the best known museums in the country, or walk through Millennium Park, a public garden on the lakefront. Wrigley Field, a ballpark, is another well-known stop for baseball fans.

FEMA’s National Risk Index (December 2025) rates the risk each natural hazard poses to the people, buildings and farms in Prospect Heights’ census tracts, against the rest of the country; all of them together, relatively high. 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 Cook County and the Chicago-Naperville-Elgin, IL-IN-WI metro.
