City of St. Clair, MO
When the mining and lumbering industries played out, they were replaced by the coming of International Shoe Company in 1922. From 1920 to 1930 the population increased from 410 to 1453– one out of three people worked in the shoe factory. Transportation to St. Louis grew with the opening of Highways 30 and upgrading of U.S. 66 (now I-44). St. Clair soon became a resort for residents in St. Louis.
After International Shoe Company closed in 1982, residents began commuting to St. Louis for employment. St. Clair today is a rural bedroom community of the metropolitan area. However, the concentrated effort by the City may write another chapter here. There are now over 15 major industries and approximately 200 retail establishments. The population of the city is about 4724, with 15,000 people living in the school district.
