Evidence, incidence, gender and age in sexual abuse of children perpetrated by children. Towards a developmental analysis of child sexual abuse

This paper describes a study of all children alleged to have sexually abused children in the city of Liverpool during a 12‐month period. The nature of the evidence in the allegations is reviewed and each designated as ‘stronger’ or ‘weaker’. On this basis annual incidence figures are calculated for children being investigated as possibly or probably having abused another child. Systematic age banding of child perpetrators is extended to a similar age banding of alleged adult perpetrators. An adolescent is more than twice as likely to be suspected of having perpetrated CSA than any other comparable age band in adulthood or childhood. This emphasizes a developmental perspective on sexual offending across the lifespan.
