This study examined spatial dependence in local suicide ideation and suicide rates among the elderly. Further, we compared the difference in spatial dependence between men and women. For the empirical analysis, we used the 2017 Korea Community Health Survey and spatial analysis. The empirical analysis shows that first, both local suicide ideation and actual suicide among the elderly are spatially dependent. Second, the spatial dependence in local suicide ideation is greater for elderly women while the spatial dependence in local actual suicide rates is greater for elderly men. The empirical results suggest that suicide prevention policies among the elderly should be refined to reflect spatial dependence in local suicides and gender differences between local suicide ideation and actual suicide regarding spatial dependence.
