Youth suicide is when a young person, generally categorized as someone below the legal age of majority, deliberately ends their own life. Rates of youth suicide and attempted youth suicide in Western societies and other countries are high. Youth suicide attempts are more common among girls, but adolescent males are the ones who usually carry out suicide. Suicide rates in youths have nearly tripled between the 1960s and 1980s. For example, in Australia suicide is second only to motor vehicle accidents as its leading cause of death for people aged 15–25, and according to the National Institute for Mental Health, suicide is the third leading cause of death among teens in the United States.
