Worldwide, an estimated 200 000 homicides occur each year among youth and young adults aged 10-29 years, making homicide the fourth leading cause of death in this age group. Eighty three percent of homicide victims in this age group are male, and nearly all of these deaths occur in low-income and middle-income countries. For each young person killed, many more sustain injuries requiring hospital treatment. Beyond deaths and injuries, youth violence can lead to mental health problems and increased health-risk behaviours, such as smoking, alcohol and drug use, and unsafe sex. Youth violence results in greatly increased health, welfare and criminal justice costs; reduces productivity; decreases the value of property in areas where it occurs; and generally undermines the fabric of society.
