What it’s like
The place. Mount Carroll is a small city in northwestern Illinois and the seat of Carroll County. Most homes are lived in by their owners, and typical home values are modest. Household incomes run a little below the county's, and the population skews older than much of the country. Winters are cold and snowy, summers are warm, and rain and melted snow fall steadily through the year.
Work. Residents work mainly in manufacturing, in schools, hospitals and social care, in restaurants, hotels and entertainment, and in shops. The largest workplaces in Mount Carroll include the County of Carroll, the West Carroll school district and Metform LLC / Machined Components. Unemployment across Carroll County is lower than a year ago, and the county has added jobs. Commutes are moderate, and few people work from home.
Things to do. Mississippi Palisades State Park, a protected area, is a short drive away, as are Lake Carroll and the Plum River. For a longer outing, White Pines Forest State Park and Apple River Canyon State Park are both a longer drive away and give room to walk and spend a day outdoors.
