Despite the overall decline in crime, gang violence continues at high levels in some cities, says the U.S. Justice Department’s Office of Juvenile Justice and Delinquency Prevention in an annual report, this one for 2010. The report estimates 29,400 gangs and 756,000 gang members throughout 3,500 jurisdictions across the U.S. It says gang-related homicides increased more than 10 percent from 2009 in cities with populations of more than 100,000.
Highly populated areas accounted for the vast majority of gang-related homicides nationally. Gang members were less likely to migrate to smaller areas and had most likely migrated for social, not illegitimate, reasons, the report said. The overall estimate of gang activity, in terms of the percent oif law enforcement agencies reporting gangs, remained stable, from 34.5 percent in 2009 to 34 percent in 2010.
