What it’s like
The place. Saint John is a small city in St. Louis County, with a population on the younger side and household incomes well below the county's. More homes here are rented than across the county as a whole, though most are still lived in by their owners. Winters are cold and bring some snow, summers turn hot, and rain and melting snow fall steadily through the year.
Work. Many residents work in restaurants, hotels and entertainment, in schools, hospitals and social care, or in shops. Costco Wholesale and Schnuck Markets are among the largest workplaces in town. Commutes are fairly ordinary in length, and a small share of people work from home.
Things to do. Several well-known places are a short drive away, including the Saint Louis Zoo, the Missouri Botanical Garden and the Saint Louis Art Museum. Forest Park, a large public garden and park, is also close by. For a longer outing, the Gateway Arch is a longer drive away.
