Every year, the FBI ranks the safest as well as the most dangerous cities in America based on a variety of crime data. This year, Ventura County cities Simi Valley (#15) and Thousand Oaks (#17) have ranked in the top 20 safest cities in America.
Once upon a time (not too long ago), these same two cities often ranked in the top five safest cities, however, with new cities and areas making it on the list every year, it has become harder and harder for these two cities to maintain their spots in the top five.
Below is the list of the top 50 safest cities in America. You can view the entire list at 2010 City Crime Rate Rankings (the list is ranked most dangerous to safest, so the safest are at the bottom of the list).
