Worldwide some 250 000 homicides occur among youth 10-29 years of age each year – 41% of the annual total number of homicides globally. For each young person killed, 20-40 more sustain injuries requiring hospital treatment. Youth violence has a serious, often lifelong, impact on a person's psychological and social functioning.

  • highlight its preventability
  • prioritize youth violence prevention in international and national health and development agendas
  • reduce youth violence by supporting countries to increase capacity and establish youth violence prevention policies and programmes, and
  • expand the global evidence base to cover more low- and middle-income countries.
