What it’s like
The place. Harristown is a small village where nearly everyone owns the home they live in, a far higher share of owners than is usual across the county. Household incomes run above the county's, and the typical home is valued in a range that reflects its small-town setting. Winters are cold and snowy, summers turn warm, and precipitation is spread fairly evenly through the year.
Work. Residents work mostly in schools, hospitals and social care, with manufacturing, retail and other services also employing many. Across Macon County, Decatur Memorial Hospital, Archer Daniels Midland Company and Decatur SD 61 are among the largest workplaces. The commute is moderate, and few people work from home. Fewer adults hold a four-year degree than in many places, and unemployment across the county has eased compared with a year ago.
Things to do. Stevens Creek runs in or beside town, and Rock Springs Conservation Area, a protected area, is also close by. A short drive away are Lincoln Trail Homestead State Memorial, a protected area, and Scovill Zoo. For a longer outing, Robert Allerton Park is a botanical garden 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 Harristown’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 Macon County and the Decatur, IL metro.
