Suicide Due To Bullying Statistics

New CDC YRBS results put cyberbullying and suicidality side by side in the same school survey, with 8.5% of students reporting being electronically bullied in 2021, while multiple meta-analyses find bullying victimization roughly doubles or more the odds of suicidal ideation and suicide attempts. The page then traces how effective school prevention can be, showing measured reductions from programs like KiVa and Olweus alongside why risk indicators such as feeling sad or hopeless almost every day (13.2%) matter for prevention before tragedies escalate.

When 1 in 5 youths are involved in bullying across studies, the mental health fallout can look like a separate crisis happening in the same school day. Using CDC Youth Risk Behavior Survey data alongside global reviews, this post connects bullying and cyberbullying to suicidal ideation and suicide attempts through pooled odds ratios and population-level patterns. The contrast is stark because bullying risk is not just correlated with suicidality, it repeatedly shows up as a measurable predictor, mediator, and target for prevention in the evidence base.
