Every 16 minutes, someone in the United States commits suicide, according to the American Association of Suicidology (AAS). Worldwide, there is a suicide every 40 seconds. The AAS says that in 2006, the most recent year for which figures are available, 33,300 people in the U.S. completed suicide. Of these, 4,189 were between the ages of 15 and 24. For every completed suicide in this young population, there are an estimated 100 to 200 attempts. Donna Amundson, L.C.S.W.
