For the fifth year in a row, crime is down in the United States, according to FBI Statistics. The 2010 statistics show a 5.5% drop in violent crimes from last year's report.
But parts of the country are getting worse.
Flint, Michigan -- the most violent city in America -- saw a 10% increase in violent crime over last year, with 2,208 violent crimes per 100,000 people. Rust Belt neighbor Detroit was only slightly safer.
St. Louis, Mo. -- last year's most violent city -- saw an impressive 18% decrease in violent crime.
The cities on this list are ranked by violent crimes including murder, forcible rape, robbery, and aggravated assault, per 100,000 people.
