Youth gangs affect society in several negative ways. Gangs are formed by both male and female adolescents and teenagers in both urban and rural areas. Gang members often identify themselves through visual symbols like tattoos, graffiti, and hand signs that represent their culture. Violence is common, as gangs frequently assault rival gang members in schools and cities, increasing crime rates. To prevent gang formation and its outcomes, such as dropping out of school and criminal activity including theft, robbery, and homicide, communities have implemented educational programs in schools to teach youth about the dangers of gangs.
