6 min readjuly 22, 2024

Gangs are complex social structures that form due to various factors like poverty, marginalization, and lack of opportunities. They provide a sense of belonging and protection for members, but often engage in criminal activities that harm communities.

Gang culture revolves around loyalty, secrecy, and strict codes of conduct. Members participate in illegal activities like drug trafficking, theft, and violence. Prevention strategies focus on addressing root causes, intervening with at-risk youth, and supporting those leaving gang life.
