An estimated 1 million people worldwide take their lives by suicide every year. It is estimated that global annual suicide fatalities could rise to 1.5 million by 2020. Worldwide, suicide ranks among the three leading causes of death among those aged 15–44 years. Suicide attempts are up to 20 times more frequent than completed suicides. Incidence of suicide in a society depends on a range of factors. Clinical depression is an especially common cause. Substance abuse, severe physical disease or infirmity are also recognized causes. The countries of the Eastern Europe and East Asia have the highest suicide rate in the world. The region with the lowest suicide rate is Latin America. Gender difference plays a significant role: among all age groups in most of the world, females tend to show higher rates of reported nonfatal suicidal behavior, males have a much higher rate of completed suicide. == Overview == In most countries the incidence of suicides is higher than the incidence of intentional homicides. A 2006 report by the World Health Organisation (WHO) states that nearly a million people take their own lives every year, more than those murdered or killed in war. WHO figures show a suicide takes place somewhere in the world roughly every 40 seconds. According to the National Institute of Mental Health, suicide contagion is a serious problem, especially for young people. Suicide can be facilitated in vulnerable teens by exposure to real or fictional accounts of suicide, including media coverage of suicide, such as intensive reporting of the suicide of a celebrity or idol. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Epidemiology of suicide」の詳細全文を読む スポンサード リンク
