St. Louis, Missouri has replaced Camden, New Jersey as the nation's most dangerous city in 2009, according to a national study by C-Q Press. Camden was the country's most dangerous city in 2003 and 2004 as well.
The study found St. Louis had 2,070 violent crimes per 100,000 residents, compared to a national average of 429.
Detroit and Flint, Michigan and Oakland, California rounded out the top five cities. For the second straight year, the safest city with more than 75,000 residents was Colonie, New York.
The annual rankings are based on population figures and crime data compiled by the FBI. Some criminologists question the findings, saying the methodology is unfair.
The Associated Press reports that Greg Scarbro, unit chief of the FBI's Uniform Crime Reporting Program, said the FBI discourages using the data for these types of rankings.
