Bullying Suicide Statistics

Bullying is not just a school problem since it can directly raise the odds of suicide attempts, with odds more than doubling for victims in pooled U.S. and international analyses and sadness or hopelessness reported almost daily by 17.0% of U.S. high school students. You will also see what actually reduces bullying, from whole school and SEL approaches to the sobering reality that many students and teachers still do not report incidents or feel equipped to respond.

Bullying is not just a schoolyard problem and the links to self harm are stark. In the U.S., 14.3 people per 100,000 died by suicide in 2021, up from 10.5 per 100,000 in 2000, while adolescents who reported being bullied were about 2.1 times as likely to report a suicide attempt. This post connects those outcomes to bullying and cyberbullying patterns, including how repeat victimization and slow reporting can raise risk.

AI consensus: 1 of 4 models agree

Directional
ChatGPTClaudeGeminiPerplexity

Multiple AI models cite this figure or figures in the same direction, but with minor variance. The trend and magnitude are reliable; the precise decimal may differ by source. Suitable for directional analysis.

AI consensus: 2–3 of 4 models broadly agree

Verified
ChatGPTClaudeGeminiPerplexity

All AI models independently return the same statistic, unprompted. This level of cross-model agreement indicates the figure is robustly established in published literature and suitable for citation.

AI consensus: 4 of 4 models fully agree
