Youth Justice Board reveals 47% rise in child sexual offences and urgent need for intervention

March 8, 2026

KEY INFORMATION:

  • The Youth Justice Board (YJB) has released an Evidence and Insights Pack on harmful sexual behaviour and misogyny by children.
  • Proven sexual offences by children increased by 47% in 2023–24, followed by a further 6% rise in the latest year.
  • One in three children report seeing online content that encourages violence against women and girls.
  • Research indicates that early school-based intervention can effectively shift attitudes toward consent and healthy relationships.
  • Most children who display harmful sexual behaviour do not go on to commit sexual offences as adults if they receive appropriate support.

The Youth Justice Board (YJB) has published a comprehensive Evidence and Insights Pack.

This document examines the prevalence of harmful sexual behaviour, misogyny, and violence among children in England and Wales. The data confirms a 47% increase in proven sexual offences by children during 2023–24, with a subsequent 6% rise in the most recent year.

New research regarding harmful sexual behaviour evidence shows that early intervention is necessary to challenge misogyny and protect young victims. The YJB notes that reported increases may stem from improved detection and reporting within the criminal justice system. However, the scale of sexual harassment in schools remains a significant concern for safeguarding professionals.

The influence of digital environments

The report highlights the role of online platforms in shaping the attitudes of young people. Algorithms often amplify misogynistic content, which can normalise harassment or coercion. According to the pack, 33% of children have viewed content encouraging violence against women and girls. Furthermore, 27% report seeing threats or images of sexual assault via digital channels.

The average age for first exposure to pornography is now approximately 13 years. Some children report exposure as early as primary school age. These experiences can negatively influence expectations regarding consent and healthy relationships.

Addressing harmful sexual behaviour evidence through education

The YJB emphasises that criminal justice responses alone are insufficient. Prevention through education is cited as the most effective method for long-term change. School programmes that focus on healthy relationships and bystander skills can successfully shift peer dynamics.

Stephanie Roberts-Bibby, Chief Executive of the YJB, said: "Violence against women and girls is a serious and growing concern across society and preventing it must start early. Understanding the role harmful sexual behaviour and misogynistic attitudes play in childhood is essential if we are to prevent harm, reduce the number of victims and make our communities safer."

Safeguarding and early intervention

Effective responses must recognise that children displaying these behaviours often have complex needs. Many have experienced personal trauma, abuse, or exploitation. The evidence suggests that with appropriate support, the majority of these children do not offend as adults.

The YJB is calling for further research to identify which specific interventions are most successful. Trusted adults, including teachers and youth workers, are encouraged to identify concerning behaviours at the earliest possible stage. This collaborative approach aims to build respectful relationships and reduce long-term harm to victims.
