In 1994, Morgan Quitno (a private research and publishing company purchased by CQ Press in 2007) began publishing reports that named St. Louis City among the "most dangerous" cities in the United States. Although the methodology for the reports changed during the 1990s, St. Louis retained its ranking in the top ten most dangerous cities, and it was named the most dangerous city in the United States three times, most recently in 2010.
