It is a project that emerged within the research field. Doctor Paolo Campana explains this with his work Breaking networks of youth serious violence carried out through the Nuffield Foundation.

Youth violence is a major public concern, both regarding young people as victims and as perpetrators.
Why is this important?
Previous research has focused on individual factors—such as trauma, adverse school experiences, and living in high-crime communities—that make young people more vulnerable to participation in serious youth violence. However, the role of the factors of how people relate and the networks in contributing to this vulnerability—who is connected to whom and why—remains under-researched.
The latest analyses on youth violence show that the way young people relate to each other is one of the most important factors in understanding both crime and victimisation. Beyond individual characteristics, the connections between people allow for the identification of risk patterns that can help better guide prevention and intervention strategies.
The study reveals that 42% of young people suspected of having committed a crime have acted in conjunction with at least one other person. This fact is especially relevant because the young people who are part of these networks are much more likely to be involved in knife crimes and to maintain links with organised crime groups. In fact, individuals more connected within the network present a much higher risk of carrying knives and participating in violent crimes than the rest of the analysed population.
The data also shows that the risk increases progressively as the number of connections grows. Each new identified accomplice significantly increases the likelihood of a young person engaging in violent acts, especially those involving the use of bladed weapons. Similarly, being connected to individuals who have been victims of violence also increases the likelihood of eventually perpetrating violence, a fact that highlights how it is concentrated and transmitted within certain social networks.
Another notable finding is the strong relationship between knife violence and other forms of serious crime. Young people involved in this type of crime show a higher participation in activities related to drug trafficking and a much stronger connection with organised crime groups. This indicates that knife violence often
forms part of a more complex criminal trajectory and is not an isolated phenomenon.
The study also questions the traditional separation between victims and perpetrators. As the severity of violence increases, it is more common for the same person to have been recorded both as a victim and as a suspect in different incidents. This coincidence is especially high among victims of violence with a knife, which reinforces the need to address these cases from a comprehensive perspective that combines prevention, protection, and intervention.
The most severely affected victims are also immersed in higher-risk social environments. A very high proportion of victims of violence with a knife have direct connections to individuals involved in this type of crime, a fact that suggests that victimisation is not random, but rather concentrated in certain social environments.
Finally, the data indicate that most of the violence among youths occurs between individuals with similar characteristics, particularly regarding age, gender, and ethnic background. However, approximately one third of the incidents involve both adults and minors, an aspect that requires specific protective responses. They also remind us that violence among girls represents a significant reality that is often overshadowed by strategies focused exclusively on boys.
Overall, the analysis demonstrates that social relationships are a fundamental element for understanding youth violence. Incorporating this perspective into public policies and police activity would allow for earlier identification of young people at higher risk and the development of more effective preventive measures before violence escalates.
