It’s Never Painless

These numbers came from the most recent edition of The Prevention Researcher, and they blew my mind. The first number is females, the second males.

Adolescent Suicidal Behavior by Gender
Seriously considered attempting suicide: 21.8% 12%
Made a suicide plan: 16.2% 9.9%
Attempted suicide: 10.8% 6%
Made a medically serious attempt: 2.9% 1.8%
Suicide Victims per 100,000: 2.4, 12.2

The girls may think about suicide more than boys, but boys actually kill themselves more than 5 times more often. Why?
