Perpetrators' Identity in Online Crimes Against Children: A Meta-Analysis

Public and police concern about internet crimes against children has been primarily typified as a stranger danger problem. However, existing research suggests a variety of perpetrator ages and relationships to the victim. A more accurate estimate will help inform prevention efforts. This study provides a meta-analysis examining the identity of perpetrators in internet crimes against children. Databases were searched for published and unpublished studies using a detailed search strategy. In total, 32 studies met full inclusion criteria. Inclusion criteria was the following: (1) the victim sample consisted of children under the age of 18 years or young adults (18-25) asked to respond retrospectively; (2) the study victims experienced abuse through the use of technology; (3) the study reported the identity of the perpetrator, either the relationship to the victim or the age of the perpetrator; (4) the study was available in English. The overall proportion of offenders under the age of 18 as a proportion of all identified offenders was 44% (95% CI: 0.28-0.60). The overall proportion of acquaintance and family offenders as a proportion of all identified offenders was 68% (95% CI: 0.62-0.75). Between study variability was explained by data source, with higher proportion of juvenile offenders in studies using survey data. This meta-analysis confirms that most perpetrators of online crimes against children are not strangers to their victims and a large portion of perpetrators are juveniles. Prevention education needs to focus more on inappropriate behavior from anyone in addition to the dangers about communicating with strangers.
