Crime & Crime Prevention

Overview

The Uniform Crime Report (UCR) and National Crime Victimization Survey (NCVS) are the U.S. Department of Justice’s two national measures of crime in the United States.^[1]

The NCVS collects information from victims on nonfatal violent and property crimes, reported and not reported to the police, against persons age 12 or older from a nationally representative sample of U.S. households. According to 2012 NCVS data, there has been an increase in both violent crime and property crime victimizations in the U.S. when compared to 2011.^[2]

The UCR Program reports a statistical compilation of offense and arrest data reported by U.S. law enforcement agencies that voluntarily participate in the program. Data from the 2012 UCR show that while the violent crime rate remained virtually unchanged when compared to the 2011 rate, the property crime rate declined 1.6 percent.^[3]
