What it’s like
The place. Summit is a village in Cook County, home to people who tend to be somewhat younger than you might expect in an older inner suburb. Incomes run well below the county's, and more households than across Cook County as a whole are in poverty, while most homes are lived in by their owners. Few adults have a four-year degree, and winters are cold, with the coldest weather in January and warm summers peaking in July, with a fair amount of rain and melted snow through the year.
Work. Residents work mostly in manufacturing, in schools, hospitals and social care, in professional and business services, and in shops. Among the largest workplaces in Summit are Talerico Martin, a commercial bakery, Summit Schools, the school district, and Frito-Lay, a wholesaler. Unemployment across Cook County is higher than it was a year ago, though the county has added a few more jobs than the year before. A typical commute is fairly long, and very few people work from home.
Things to do. SeatGeek Stadium is in or beside town, so live games and concerts are close to home. A short drive away are the United Center, a stadium, and Brookfield Zoo. Farther afield, the Art Institute of Chicago is a museum 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 Summit’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 Cook County and the Chicago-Naperville-Elgin, IL-IN-WI metro.
