Who abuses children? Overview of variables This section examines the perpetrators of technology-facilitated child sexual exploitation and abuse using the comparable seven-indicator measure described in Section 1. Analyses in this section are conducted at the incident level rather than the child level. This is because children may have been subjected to more than one form of technology-facilitated sexual exploitation and abuse measured in the survey. Subsequently, each incident may have involved a different perpetrator. To facilitate incident-level analyses, the data were reshaped so that each reported instance of technology-facilitated sexual exploitation and abuse represented a single observation. Consequently, the numbers and proportions presented refer to individual instances of technology-facilitated sexual exploitation and abuse, rather than the number of children subjected to abuse. To enable comparisons across both rounds of Disrupting Harm, harmonized perpetrator categories were developed to account for differences in the perpetrator response options between survey rounds. These harmonized categories account for changes introduced in the second round of Disrupting Harm, where perpetrator response options were expanded and further disaggregated by age to provide more precision. Perpetrators were grouped into three overarching categories: strangers, someone the child knows, and unidentified perpetrators. Through Children’s Eyes Appendix 66
