The statistics presented address reported crimes, arrests, dispositions of adult felony arrests, adult probation, criminal justice personnel, citizens' complaints against peace officers, domestic-violence-related calls for assistance, and law enforcement officers killed or assaulted. Statistics reported for previous years show the historical trend for reported crime in California. The crime data show that there was a decrease in the crime rate per 100,000 population for every violent and property offense. From 2009 to 2010, the violent crime rate decreased 6.9 percent (from 453.6 to 422.3), reaching its lowest level since 1968 (411.1). The 2010 total arrest rate of 4,559.1 per 100,000 population at risk is 6.0 percent lower than the 2009 total arrest rate of 4,849.0.
