20-million children suffered online sexual abuse in one year: Unicef

About 20-million internet-using children across 21 countries were subjected to sexual exploitation or abuse on digital platforms in a single year, with most cases occurring on social media platforms, a new report by the UN children’s charity said on Thursday.

More than one in five children aged 12 to 17 across Africa, Asia, Latin America and Eastern Europe experienced at least one form of sexual abuse or exploitation on online platforms in the year before being surveyed, the Unicef report estimated.

The number of children subjected to the abuse globally is certain to run into many tens of millions, it said.

The research, which Unicef described as one of the largest studies of its kind, was based on national representative surveys collected between 2020 and 2025 of about 21,000 internet-using children in the 21 countries, which included Kenya, Pakistan, Brazil and Serbia.

“While the report doesn’t provide any specific evidence of abuse, we’ll continue to fight child exploitation aggressively across our apps and support law enforcement in prosecuting the criminals behind it,” the Meta spokesperson said.

Snapchat pointed to a blog post by global head of platform safety Jacqueline Beauchere, who said the company was actively combating online sexual extortion through proactive detection, account removals, user reporting tools and safety features designed to protect vulnerable users.

TikTok said it has built a range of safeguards to protect minors, including:

Across nine countries where data was collected, an estimated 1.1-million children reported having AI-generated sexual images or videos created depicting them

The Unicef report said more than half the cases involved someone the child knew, including friends, relatives or romantic partners, while 38% of children first encountered the perpetrator online.

Fewer than 1% of cases involving children were reported to police, a social worker or a helpline, according to the research.

The report also highlighted growing concerns over artificial intelligence (AI). Across nine countries where data was collected, an estimated 1.1-million children reported having AI-generated sexual images or videos created depicting them.

Children who experienced tech-facilitated sexual exploitation were around four times more likely to report suicidal thoughts or self-harm, and reported significantly higher levels of anxiety than their peers, the research said.

“These experiences cause profound emotional and mental distress. Many children suffer in silence, unsure where to turn for help,” Unicef executive director Catherine Russell said.

Unicef urged governments and technology companies to strengthen safety measures on digital platforms, update laws to address evolving forms of abuse including AI-generated content, and improve child protection and reporting systems.
