Juvenile arrests in the U.S. declined slightly in 2007, but the juvenile arrest rate for the key crimes of murder and robbery have increased significantly in recent years after a long decline, says a new U.S. Justice Department compilation. Juvenile arrest totals generally are viewed as a proxy for juvenile crime rates generally, although with young people a single crime may generate multiple arrests. The juvenile arrest rate for murder in 2007 was 24 percent higher than the 2004 low, but 72 percent under the 1993 peak. For robberies, the arrest rate was 41 percent greater in 2007 than in 2002 but still 47 percent under its 1995 peak. The report gave a state by state comparison of arrest rates, but most states did not provide complete reports. Of the states that reported more than 90 percent of juvenile arrests the highest per capita in violent crime were Delaware, Maryland, Florida, Pennsylvania, and California. Despite the widespread perception that juveniles are involved in a high percentage of crimes overall, the report found that those 10 to 17 years old accounted for 16 percent of violent crime arrests and 26 percent of property crime arrests in 2007.
