The City of Round Rock ranks as the 13th safest city in the United States, according to a national survey of crime statistics of cities with a population of 75,000 or more.

The survey, released Nov. 19, 2007, by CQ Press, used rates for murder, rape, robbery, aggravated assault, burglary and motor vehicle theft for its rankings. All cities of 75,000 population or more that reported data to the FBI in 2005 for the six categories of crime measured for the survey were included. Two years ago, Round Rock ranked as the 8th safest city.
