| Outline of Final Research Achievements |
Owing to the spread of the novel coronavirus diseases, the research period needed to be extended by one year. Nonetheless, an effective utilization of existing resources and a flexible adoption of an approach different from the original plan made it to possible to continue this research project. As originally planned, factors behind declining marriage rate and birth rate had been investigated. The results showed that youth employment and economic conditions have a strong impact on both factors, suggesting that gender structuring, especially in the family domain, is associated with low fertility in Japan.

| Academic Significance and Societal Importance of the Research Achievements |
これまで、少子化対策として様々な施策が講じられてきたものの、いずれも決定的な効果を得られていない。本研究では、これまで推進されてきた政策が結婚や出生にどのような影響を与えていたのかを実証分析した。その結果、保育所の拡充や三世代同居の推進は子どもの数に有意な効果をもたらさなかったことが明らかになった。一方で、若年層の不安定な雇用は、非常に強く未婚化につながっていた。結婚や出生に対する働き方や収入の影響は、とくに男性において顕著であり、公的領域、私的領域におけるジェンダー格差との関連性を示唆する。
