New numbers released by the Criminal Justice Statistics Center indicate that last year, California posted its lowest number of juvenile arrests in more than half a century. The 2011 total of 149,563 juvenile arrests is the lowest annual tally since 1957; the first year statewide records were kept. Even when accounting for a larger youth population in the state, recent figures indicate California teens are less likely to be arrested for severe crimes, such as murder and rape, than young people 50 years ago. Since the 1970s, youth crime has been on a downward spiral in the Golden State, with the number of violent offenses perpetrated by juveniles plummeting by 50 percent over the last four decades. With reports from all 58 counties analyzed, researchers noted a 17 percent decrease in California juvenile arrests from 2010 to 2011, with violent and property offenses dropping by 16 percent, and status and misdemeanor offenses dropping by 21 percent.
