Suicide is the act of intentionally causing one's own death. Suicide is often committed out of despair, the cause of which can be attributed to a mental disorder such as depression, bipolar disorder, schizophrenia, alcoholism, or drug abuse. Stress factors such as financial difficulties or troubles with interpersonal relationships often play a significant role. Over one million people die by suicide every year. The World Health Organization (WHO) estimates that it is the 13th leading cause of death worldwide and the National Safety Council rates it sixth in the United States. It is a leading cause of death among teenagers and adults under 35. The rate of suicide is far higher in men than in women, with males worldwide three to four times more likely to kill themselves than females. There are an estimated 10 to 20 million non-fatal attempted suicides every year worldwide.
