More than 300 million children across the globe are victims of online sexual exploitation and abuse each year, research suggests. In what is believed to be the first global estimate of the scale of the crisis, researchers at the University of Edinburgh found that 12.6% of the world's children have been victims of nonconsensual talking, sharing and exposure to sexual images and video in the past year, equivalent to about 302 million young people. A similar proportion " 12.5% " had been subject to online solicitation, such as unwanted sexual talk that can include sexting, sexual questions and sexual act requests by adults or other youths. Offences can also take the form of "sextortion", where predators demand money from victims to keep images private, and abuse of AI deepfake technology. The US is a particularly high-risk area. The university's Childlight initiative " which aims to understand the prevalence of child abuse " includes a new global index, which found that one in nine men in the US (equivalent to almost 14 million) admitted online offending against children at some point. Surveys found 7% of British men, equivalent to 1.8 million, admitted the same. The research also found many men admitted they would seek to commit physical sexual offences against children if they thought it would be kept secret. Child abuse material is so prevalent that files are on average reported to watchdog and policing organisations once every second.
