Preadolescents are not the only young people affected by the upward trend. The fact is that suicide has become the second leading cause of death across the entire 10-24 age group. Since 2007, according to the CDC report, suicides among 15-19 year-olds have increased by 76%; rates are also accelerating among 20-24 year-olds. For these two age groups, the suicide rate now exceeds the homicide rate. Nonetheless, while suicide at any age is tragic, a psychologist at Emory University (CDC’s neighbor) told NPR that she was particularly disturbed “to see a significant increase in very young people as young as age 10.” What is equally disturbing is that experts are at a loss to explain the suicide spike in the very youngest.
