A global knowledge platform for preventing violence

The Violence Prevention Information System (Violence Info) collates published scientific information on the main types of interpersonal violence. This includes information on prevalence, consequences, risk factors, and prevention and response strategies. It also describes what countries report about their actions to address violence. This version contains most of the major features, but remains a work in progress with more studies to be added. User feedback is welcome, including suggestions for features and additional studies, provided they meet the inclusion criteria (see methodology on the About page).


Globally, some 470 000 people are victims of homicide every year. Hundreds of millions more men, women, and children suffer non-fatal forms of interpersonal violence, including child maltreatment, youth violence, intimate partner violence, sexual violence, and elder abuse, with many suffering multiple forms. Such violence contributes to lifelong ill-health – particularly for women and children – and early death.


Violence often blights the lives of individuals for decades. Beyond death, physical injury and disability, violence can lead to stress that impairs the development of the nervous and immune systems. Consequently, people exposed to violence are at increased risk of a wide range of immediate and life-long behavioural, physical and mental health problems, including being a victim and/or perpetrator of further violence. Violence can also undermine the social and economic development of whole communities and societies.

Violence is preventable

Violence is not an inherent part of the human condition. It can be predicted and prevented. In recent decades, data-driven and evidence-based approaches have produced knowledge and strategies that can prevent violence. These include interventions at individual, close relationship, community and societal levels.
