According to Wikipedia, Clayton is a city in the county seat of St. Louis County, Missouri, United States, and borders the city of St. Louis. The population was 15,939 at the 2010 census.

Now this is Wikipedia so take that with a grain of salt. I'll wait for Missouri Freepers to confirm or to deny.
