Outline of Final Research Achievements

This study discusses the direction of regional regeneration from migration trend and population distribution change within cities, especially those of aged people, targeting local cities which have experiencing population decline from earlier time. The main findings obtained are summarized as follows. First, although population re-centralization was certainly observed earlier in greater metropolitan area, such as Tokyo metropolitan area, it spread rapidly to the metropolitan area of local cities after 2000s. Second, the trend of population re-centralization seemed to be more striking among aged people. As it is hardly imaginable to the population distribution of local cities go toward sprawling again in the situation where aging society with fewer children and population decline are projected to proceed heavily in the future, it will be necessary to seek new regional planning frame along with the recent population flows.
