Sociological survey presented in this article is devoted to one of the aspects of sociology of deviation, namely suicidal behavior among adolescents. These problems are urgent for Russia in general and for each of its region. The situation is aggravated by the absence of a system of control over information resources, lack of reliable official data on the specifics and dynamics of suicides in the individual regions, inadequate social protection of this age group as well as the absence of systematic work in this direction. The author proposes to analyze the dynamics of distribution of suicide in the Altai territory as the conditions for the repetition of risky behavior and explore the features of suicidal behavior of adolescents in differentiated groups with different levels of risk manifestation. Factors to explain suicide risks of teenagers in Altay region are described in this article. The analytic material is considered from a position of institutional, social group and individual level. The information, which is presented in this article, can be interesting for specialists in sociology of youth, risk and deviations.
