What it’s like
The place. Johnsburg is a village in McHenry County where nearly everyone owns the home they live in, and household incomes run higher than across the county as a whole. Fewer adults hold a four-year degree than you might expect given those incomes, and a small share of residents live below the poverty line. Winters are cold, with January the coldest month and a fair amount of snow, and summers are warm, with July the warmest.
Work. Residents work mostly in schools, hospitals and social care, followed by shops, manufacturing and the building trades. Within the village, the largest workplaces include the school district, Johnsburg CUSD 12, along with RoofOptions, a roof membrane installer, and Prem Magnetics, which makes electronic capacitors. Unemployment across McHenry County has risen over the past year, though the county has added a few more jobs.
Things to do. Several state-protected natural areas lie a short drive away, including Moraine Hills State Park, Chain O' Lakes State Park and Volo Bog State Natural Area, along with Wooster Lake. Farther afield, a longer drive brings you to Geneva Lake and to Six Flags Great America, an amusement park. Many residents take a typical commute that is fairly long, and some work from home.

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