日本における高齢者の所得格差の地域間格差

Abstract

This study focuses on the rapid aging in Japan and aims to analyze the gap in the income of the aged between the regions. As a result of an analysis, the following conclusions were drawn. First, income per capita decreases in the regions with the progress of aging. Especially, as the fewer the population in the region, the higher the ratio of the aged became, it turned out that the distribution of incomes became worse. This means that the ratio of aging is in the opposite relationship with the income per capita. This suggests that the development of the local economy would be difficult unless a policy against aging is promoted. Second, it turned out that there was a large gap in income in the aged over 75, and there was a gap between regions. The Gini’s coefficient was higher in those over 75, and there was a little difference between regions, but there was a trend of the expansion of the gap. Also, it turned out that the difference in income has nothing to do with the reception of livelihood protection. Accordingly, it is expected that the increase in the number of senior citizens who live alone due to urbanization becomes a social issue of the elderly poverty. Through the analysis, it was found out that population aging greatly affects the growth and distribution in the local economy. It is important to respond to aging by mitigation, but it is necessary to change our way of thinking in a new way, not bound to the patterns in the past so that we can continue to develop the economy in spite of aging.
