The rates and numbers of elderly suicide in Korea have been increased during 1985-1998. This indicates the seriousness of the problems which the elderly are faced with. So many late-life problems may push older people across the edges. Those in unbearable situations may call out fur helps, they may try to cope with various ways, or they may commit suicides. Because it is widely believed that suicide among the elderly can be understood as a personal solution or alternative to late-life problems in old age, the elderly`s suicides seem to be an appropriate indicator in estimating seriousness of late-life problems. A comparison of the history of suicide research with other populations shows that the several late-life problems have been found with placing an individual elder at risks for increasing suicidal behaviors Research has identified such problems as financial insecurity, retirement, loss of social roles, physical illness, lack of social supports, and loneliness as the problems that increase the incidence of suicidal behavior. Though it is difficult far us to explain and understand the phenomenon of the elderly`s suicide because of its complexity, we need to ascertain problems and social conditions behind suicides and also to prepare for some appropriate policy-tasks in light of social welfare for the aged, through examining the phenomenon. For explaining the elderly`s suicide, the theoretical orientations are based on sociological perspectives in the paper. From the standpoints of social integration theory and exchange theory, this study is to examine the relationship between late-life problems and suicide. These two may have been fruitfully employed in conjunction with each other. Finally, this study would identify urgent late-life problems related with the elderly`s suicide and suggest the relevant policies for Korean elders. Sometime in the near future, the government should be required to provide social welfare programs for the elderly, particularly for those at risk for increasing suicidal behaviors.
