Child pornography—better known as child sexual abuse material (CSAM)—represents a severe form of exploitation and victimization of children, leaving the victims with emotional and physical trauma. This study presents an analysis of local patterns of CSAM consumption across 1341 French communes in 20 metropolitan regions of France between March 16 to May 31, 2019, using fine-grained mobile traffic data of Tor network-related web services. This research provides public health officials with valuable information to prioritize target areas for public awareness campaigns as another step to fulfill the global community’s pledge to target sustainable development goals: end abuse, exploitation, trafficking and all forms of violence and torture against children.
