Violent crimes are classified in four categories consisting of murder, rape, robbery and aggravated assault. Crime statistics are initially collected by individual police departments at the time a criminal defendant is booked at a police station however this data is collected and compiled nationally by the FBI in what is called the UCR (Universal Crime Reporting Program). This allows the nation and individual law enforcement agencies to assess how effective their tactics are working to combat particular crime types as well projecting crime trends to show where new strategies need to be employed.

Violent crimes have been on a downward trend overall for 2010 totaling at an estimated 1,246,248 reported violent crimes throughout the nation.
