Social security and divorce in Japan Original Research Article

The purpose of this paper is to explain variations in the divorce rates across prefectures in Japan over the 20-year period between 1982 and 2002. This paper examines the various factors which may affect divorce rates including: the effects of the generosity of social welfare; the income of females relative to males; the female employment rate; the vacancy rate; a shift to no-fault divorce; and social stigma. There are three major findings of this paper. First, the generosity of a particular prefecture in approving the livelihood protection benefits (LPBs) has a statistically negative impact on the divorce rate. Moreover, social stigma has negative impacts both on the divorce rate and the generosity of social security benefits. Finally, political conservatism has a negative impact on the proportion of needy people who receive LPB. The findings of this paper imply that in order to become eligible for the social security benefits, married couples may be more likely to dissolve their marriage in those prefectures where the provision of the LPB is not so generous.
