Youth violence includes various behaviors, such as fighting, bullying, gang-related violence, and homicide. These behaviors involve the intentional use of physical force or power by a young person between the ages of 10 and 24 to threaten or harm other people. Young people can be involved with violence as victims, perpetrators, or witnesses.
