The article focuses on the study of suicide worldwide and Ukraine in particular. The phenomenon of suicide is relevant in all corners of the world, it affects people of all nations, cultures, religions, articles, and classes. The scientific community in many countries around the world demonstrates indifference to the problem of suicide; Accordingly, suicide is gradually becoming one of the leading causes of death worldwide. Thus, suicide ranks 15th among the leading causes of death. WHO statistics show that suicide is committed twice as often as murder, and emphasizes that this phenomenon is global and reaches critical levels every year. We have analyzed the regulatory framework for suicide at the global level. For example, over the last decades, since 2000, due to the incredible efforts of WHO, this problem has begun to receive national attention. In the developed world, many regulations on suicide prevention have been developed and adopted. In the course of scientific research, we found out that suicide and Ukraine is the seventh cause of death, which confirms the criticality of the problem and the need for its fastest solution. We believe that there is a need today to support such categories of persons as children and young people, servicemen, convicts, and the elderly. The article examines the experience of such foreign countries as the USA, Azerbaijan, Israel, Canada, Australia, New Zealand, Great Britain, and other European countries of the world. Finding out what prevention and prevention measures they have implemented in national suicide prevention programs, we see the possibility of their implementation in Ukraine and are convinced of their effectiveness. According to the results of scientific research, we will develop an administrative and legal mechanism for suicide prevention in Ukraine, which can work if all the steps of the algorithm for reducing suicide rates are fulfilled. Keywords: suicide, administrative and legal mechanism, the algorithm of actions, statistics, suicide rate.
