The place. Caseyville is a village in St. Clair County, Illinois, home to a small community where most households own the place they live in. Incomes run below the county's, and the typical home is modestly priced. Few adults hold a four-year degree, and winters are cold, with January the chilliest month, while summers are warm, July the warmest, and the year brings a fair amount of rain and melted snow.

Among the larger workplaces in Caseyville are Advancepierre Foods, a frozen specialty food maker, Soil Installers, a construction management firm, and Illinois Central School Bus.
