OJJDP has released Juvenile Arrests 2011. This bulletin draws on data from the Federal Bureau of Investigation’s (FBI) Uniform Crime Reporting (UCR) Program. Using UCR data that local law enforcement agencies across the country provide, the FBI prepares its annual Crime in the United States report, which summarizes crimes known to the police and arrests made during the reporting calendar year. OJJDP’s annual Juvenile Arrests bulletins analyze data from the Crime in the United States report to characterize the extent and nature of juvenile crime. Among other findings, the bulletin reports that juvenile arrests in 2011 decreased 11 percent and juvenile violent crime arrests decreased 10 percent over 2010.
