Online Bullying Statistics

GITNUXREPORT 2026

Online Bullying Statistics

Cyberbullying touches far more than “mean messages”: pooled victimization links to higher anxiety, depression, loneliness, sleep problems, and even suicide related outcomes, while reportable cyber harms are still underused by adults. At the same time, large platform scale and tighter rules are colliding with gaps in visibility, with schools and educators repeatedly saying they need better training and students still reporting cyberbullying at rates well above single digits.

Cyberbullying and online harassment have become so common that the scale of reporting and moderation is now measured in millions of removal requests, including 1.5 million take down requests handled under applicable rules for harassment and threats. Yet the same research also shows a troubling mismatch between how often young people experience harm and how consistently it is captured, from victims and perpetrators to hateful content exposure that can normalize hostility. Let’s look at what the latest evidence says about prevalence and the mental health risks linked to online bullying, and why the differences in measurement matter.

Prevalence Interpretation

Under the “Prevalence” angle, the data show that online bullying is widespread, with between 14% and 26% of students reporting cyberbullying in recent periods in the United States and England reporting 8% bullied online in 2018 alongside a much higher 42% reporting at least one online harm in 2021.

Risk Factors Interpretation

Risk factors linked to online bullying are clear, with a 2021 review showing cyberbullying perpetration increases the likelihood of substance use and related risk behaviors, a 2020 meta-analysis finding cyberbullying victimization is tied to higher odds of anxiety-related outcomes, and in the U.S. 6% of students reporting romantic relationship-based cyberbullying suggests these harms can be especially pervasive.
