Abstract

This study aims at analyzing the population structure from 1980 to 2020 in terms of generation balance between the child generations who were born from 1950s to 1970s and their mother generations. It also aims at specifying the municipalities in the Tokyo Metropolitan Area where the population will be out of balance in near future. In this study, the Generation Balance Index based on the five-year age group is employed to make it possible to adapt this method to the further analysis. By comparing the generation balances of populations within the child generation, it is clarified that the cohorts born in 1960s and 1970s tend to move to the central area unlike the cohort born in 1950s. From the analysis of the future population, it is clarified the phenomenon of 'Empty Nest' in municipal level may occur mainly in the suburbs which were most rapidly urbanized in the 1960s and 1970s.
