According to Forbes, Detroit is America's most dangerous city. Forbes based it on the city's rate of 1,200 violent crimes per 100,000 people and other violent crime statistics from the Federal Bureau of Investigation.
"Detroit has, historically, been one of the more violent cities in the U.S.," says Megan Wolfram, an analyst at iJet Intelligent Risk Systems, a Maryland-based risk-assessment firm. "They have a number of local crime syndicates there--a number of small gangs who tend to compete over territory."
The second most dangerous city in America is Memphis, in Tennessee. It has a population of 1,295,670 and the number of violent crime per 100,000 is 1,218. The third is Miami in Florida.
