Adolescent Suicidal Behavior Statistics

GITNUXREPORT 2026

Adolescent Suicidal Behavior Statistics

Nearly 1 in 5 U.S. high school students reported serious consideration of suicide in 2021, yet the page shows how risk spreads outward through planning, depression, and mental health service contact that can lag behind. You will also see where the biggest pressure points often come from, including bullying, violence, substance use, and anxiety, alongside outcomes like a 25% reduction with safety planning and the sharp rise in U.S. youth suicide death rates from 6.1 to 9.1 per 100,000 between 2011 and 2022.

In 2022, the U.S. suicide death rate for ages 10 to 19 rose to 9.1 per 100,000, up from 6.1 per 100,000 in 2011. At the same time, many early warning signs appear well before a death, including 18.8% of high school students reporting serious consideration of suicide in 2021. This post brings those outcomes together with risk factors like depression, bullying, substance use, violence exposure, and mental health service contact to show how different parts of the picture fit.
