Estimation of the Elderly Poverty Rate due to Household Separation and Policy Response

Abstract

This study demonstrates that elderly poverty can be caused not only by the lack of income among the elderly but also by non-economic factors such as separation from children, elderly divorce, and other related factors. There are several types of elderly households, but it was found that household separation occurred the most in type 1 (elderly/child generation). In the process of the separation of elderly households, the number of households increased by 5.4% from 2009 to 2020, while household current income decreased by 8.2% and the number of household members decreased by 0.25 persons. From 2009 to 2020, the Gini Coefficient change value for the elderly households was estimated to be —0.022 points, and the Gini Coefficient change value for the combined effect and segregation effect of elderly households was estimated to be –0.091 points and 0.069 points, respectively. During the same period, the change in the value of the elderly poverty rate was estimated to be –7.4% points, the combined effect was –32.1% points, and the segregation effect was 24.6% points, respectively. The analysis of the Gini Coefficient and the poverty rate for the elderly found that the overall inequality and poverty rate of elderly households decreased over time, but the negative segregation effect on inequality and poverty rate continued to increase. This analysis suggests that even if income levels continue to increase (by combined effect), inequality and poverty among the elderly may still increase. Therefore, this study suggests that it is necessary to promote a mixture of family policy and income policy in order to become an effective retirement income security policy.
