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.
