New census figures tell us what our biggest cities are. Kansas City is still number one, and its margin over St. Louis is growing a little bit. New Census Bureau estimates say Kansas City has grown a little and St. Louis continues to leak population. Springfield, Independence, and Columbia are next, then Lee’s Summit and St. Joseph. The Census Bureau says Lee’s Summit has surpassed St. Joseph in the rankings. Then three St. Louis suburbs – St. Charles, O’Fallon and St. Peters round out the top ten.
