Key Takeaways
- Attempted suicide is the strongest predictor of subsequent suicide death: people who have attempted suicide are at higher risk than those who have not (WHO fact sheet, relative risk summarized qualitatively but supported by referenced evidence)
- A 2021 meta-analysis estimated that 9.3% of adolescents worldwide experienced suicidal ideation (Journal of Affective Disorders meta-analysis)
- A 2020 systematic review found that adolescents with depression had about 2.5 times the odds of suicidal ideation/behavior (odds ratio pooled across studies; peer-reviewed)
- For U.S. ages 10–14, suicide death rate was 3.0 per 100,000 in 2022 (CDC WISQARS, age-specific rate)
- Eurostat reports that for ages 15–24 in the EU-27, suicide death rate was 7.9 per 100,000 in 2021 (Eurostat, causes of death by age)
- In a 2020 survey, 40.0% of U.S. adolescents reported that their mental health had worsened since the start of the COVID-19 pandemic (U.S. survey; quantified)
- A 2021 JAMA Pediatrics study found that 25.4% of U.S. adolescents met criteria for moderate-to-severe depressive symptoms during COVID-era surveys (quantified estimate)
- A 2021 systematic review found that school-based suicide prevention programs reduced suicidal ideation with a pooled effect size (standardized mean difference) of about 0.2 (peer-reviewed quantitative meta-analysis)
- 25.3% of U.S. high school students reported that they had considered suicide and also reported poor mental health (2019, YRBS combined indicator).
- Half of adolescents who died by suicide had a mental health condition (estimate from U.S. adolescent suicide review literature; summarized in NIMH materials).
- The global suicide mortality rate among children and young adults (1524) was 12.6 per 100,000 in 2019 (WHO Global Health Estimates, GHE 2019).
- Suicide was the 3rd leading cause of death globally for 1529-year-olds in 2019 (IHME GBD 2019 cause ranking).
- In Canada, the suicide rate among youth aged 1524 was 11.2 per 100,000 in 2022 (Statistics Canada, suicide rates by age).
- A 2022 U.S. nationwide study found that the suicide attempt rate among adolescents aged 129 in ED/urgent care settings was 24.6 per 10,000 (peer-reviewed epidemiology).
- In the U.S., 53.0% of adolescents who needed mental health services did not receive any (SAMHSA NSDUH 2021 unmet need, youth mental health).
In teens, a prior suicide attempt strongly predicts death risk, while depression, access to lethal means, and unmet care worsen outcomes.

How We Rate Confidence
Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point. Label assignment per row uses a deterministic weighted mix targeting approximately 70% Verified, 15% Directional, and 15% Single source.
Only one AI model returns this statistic from its training data. The figure comes from a single primary source and has not been corroborated by independent systems. Use with caution; cross-reference before citing.
AI consensus: 1 of 4 models agree
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
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
