| Outline of Final Research Achievements |
Conventional explanations on the Demographic Transition (DT) omits impacts of structural changes of population. The simulation analyses on DT, however, indicated that the changes had significant effects on crude death, and birth rates through the population momentum thus on the process itself when the transition was quick. The structural changes should be an essential part of the process and be included in the theory. As for the empirical findings, the childless rate has been increasing (even ever married) in Japan and the childless orientation accompanying late marriage and unmarried / divorce is currently prevailing as well. Findings from careful examination of the low fertility and the policy measures in Japan, suggest difficultly “to correct” the fertility situation by a single specific measure. Instead promoting comprehensive measures toward life and family formation with the life-course perspectives. These are all unique and creative viewpoints from the current study project.
