What it’s like
The place. Winthrop Harbor is a small village in Lake County, Illinois, where nearly all of the homes are lived in by their owners. Household incomes run below the county's, and few residents live below the poverty line. Winters are cold, with January highs just around freezing and lows well below it, and summers are warm; rain and melted snow add up to a fair amount over the year.
Work. Residents work mostly in manufacturing, in schools, hospitals and social care, in professional and business services, and in shops. Across Lake County, some of the largest workplaces are AbbVie, Abbott and Discover Financial Services. The commute to work is a fairly long one, and a small share of people work from home.
Things to do. Adeline Jay Geo-Karis Illinois Beach State Park, a beach, is a short drive away, as is Library Park for a quieter afternoon outdoors. Six Flags Great America, an amusement park, is also a short drive away. The Chicago Botanic Garden, a botanical garden, is a longer drive.
