Outline of Final Research Achievements

This study is aimed to examine the sustainability of the long-term care insurance system based on the demographic dynamics of the elderly, as the baby-boom generation is about to enter the later stages of aging. The study quantitatively clarified the factors and their impact on the social dynamics (migration) of the elderly, which are less verified than the natural dynamics. Furthermore, the ideal form of the long-term care insurance system based on the social dynamics of the elderly was considered.
Despite the spread of the new coronavirus and the resulting delays in research execution, a total of six papers were published throughout the research period. Two of them were published in peer-reviewed English-language journals. In addition, an article summarizing the research results was published in a journal whose main readers are local government officials.

Academic Significance and Societal Importance of the Research Achievements

高齢者の社会移動は人口学・地理学・経済学・環境学・公衆衛生など様々な学術分野で注目されており，その研究蓄積も膨大である。しかしながら，日本において高齢者の移動を取り扱っている研究は相対的に少なく，要因分析もまだ途上にある。
世界でも高齢化に進展において最先端を走っている日本において，高齢者の社会動態のあり方を定量的に把握し，その社会的なインパクトを検討することは学術的な意義のみならず政策的な意義も大きい。当然ながら，日本が直面している多くの社会課題に示唆を与えるものとなる。
