Approximately 0.5-1.4% of people die by suicide, roughly 12 per 100,000 individuals per year. Three quarters of suicides globally occur in the low and middle income countries. Rates of completed suicides are generally higher among men than among women, ranging from 1.5 times as much in the developing world to 3.5 times in the developed world. Suicide is generally most common among those over the age of 70; however, in certain countries, those aged between 15 and 30 are at the highest risk. Europe had the highest rates of suicide by region in 2015. There are an estimated 10 to 20 million non-fatal attempted suicides every year. Non-fatal suicide attempts may lead to injury and long-term disabilities. In the Western world, attempts are more common among young people and among females.
Suicide, from Latin suicidium, is "the act of taking one's own life". Attempted suicide or non-fatal suicidal behavior is self-injury with the desire to end one's life that does not result in death.Assisted suicide is when one individual helps another bring about their own death indirectly via providing either advice or the means to the end. This is in contrast to euthanasia, where another person takes a more active role in bringing about a person's death.Suicidal ideation is thoughts of ending one's life but not taking any active efforts to do so. In a murder-suicide (or homicide-suicide), the individual aims at taking the life of others at the same time. A special case of this is extended suicide, where the murder is motivated by seeing the murdered persons as an extension of their self.
The normal verb in scholarly research and journalism for the act of suicide is commit. Some advocacy groups recommend saying completed suicide, took his/her own life, died by suicide, or killed him/herself instead of committed suicide. Opponents of commit argue that it implies that suicide is criminal, sinful, or morally wrong.
