Homicides and Violence Rates Interpretation
While gangs represent only 13% of the national murder problem, they are the overwhelming and hyper-concentrated engine of homicide in America's cities, where a shockingly small cohort of young men—who are 50 times more violent than their peers—drive a brutal cycle of retaliation that claims thousands of lives year after year.
