Abstract

The purpose of this study is to compare changes in suicide rates among Korean regions since the late 1990s. Especially, the main goal of this study is to reveal whether there is a persistent pattern of suicidal risk level at the spatio-temporal level. If the occurrence of suicide is temporally and spatially fixed at the local level, we can find the evidence that the environmental forces that lead to the abnormal suicide in Korean society are differentiated not only at the social level but also at the local level. In order to examine such patterns, this study empirically test the spatial distribution of suicide incidence and the regional distribution of the longitudinal combination trajectories of age-related suicide risk. First, we examined the spatial autocorrelation level of suicide rates among age groups longitudinally. Second, we conducted trajectory clustering analysis to classify the types of age-related suicidal risk structures, mapping the regional distribution of trajectory types, and multinomial logistic regression analysis. This study finds that the regional risks of suicide in Korea
have maintained the fixed sequence structure throughout the research period and that the distribution of suicide risk was fixed around the characteristics of the region and administrative districts. At the conclusion, some policy implications were
presented by discussing the results.
