What it’s like
The place. Deer Park is a village in Lake County, Illinois, home to a small community of owners and families. Incomes here run well above the county's, hardly any households fall below the poverty line, and most homes are lived in by their owners. Typical home values are high, and a large majority of adults hold a four-year degree. Winters are cold, with January highs near freezing and lows well below it, and a good deal of snow falls each year. Summers are warm, and precipitation is spread across the year.
Work. Residents work mostly in professional and business services, in schools, hospitals and social care, in banks, insurance and property, and in manufacturing. Across Lake County, some of the largest workplaces are AbbVie, Abbott and Discover Financial Services. Commutes are fairly long, and a good number of people work from home. Unemployment across the county is lower than a year ago, though the county has fewer jobs than the year before.
Things to do. The Catlow Theater, a theatre in or beside town, is the closest place on the list for an evening out. A longer drive brings you to the Chicago Botanic Garden, a botanical garden, and to Six Flags Great America, an amusement park. Brookfield Zoo is also a longer drive away, for a day with grandchildren or visitors.
