In 2021, gangs were tied to 13% of all US homicides, yet the ripple effects go far beyond the death toll. CDC research found gang members are 50 times more likely to carry firearms than non-gang youth, and the annual price to communities tops $15 billion in medical, justice, and lost productivity. The mix of city level concentrations, shifting enforcement responses, and prevention results makes these statistics uncomfortable but essential to understand.
