What it’s like
The place. Sumner is a small city in Lawrence County, in the southeastern part of Illinois. Its residents are somewhat younger than in many small towns, and homes here cost far less than in most of the country. Winters are cold with some snow, summers turn hot, and the year brings a good deal of rain.
Work. Many residents work in schools, hospitals and social care, with manufacturing, shops, and transport and warehousing also employing a good number. Across Lawrence County, the largest workplaces include Toyota Boshoku Illinois, which makes motor vehicle interior systems, the Illinois Department of Corrections, and the Lawrence County school district. Few adults here hold a four-year degree, and a typical commute is a short drive, with very few people working from home. Across the county, incomes are modest and unemployment has eased over the past year, though the number of jobs has slipped slightly.
Things to do. Red Hills State Park is a protected area in or beside town, a handy place for time outdoors. A longer drive takes you to the history of the Wabash valley, including George Rogers Clark National Historical Park, a museum and memorial, and the Forts of Vincennes. Rivers such as the Embarras and the White River are also 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 Sumner’s 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 Lawrence County.
