A survey by the International Health Policy Department, including visiting researcher Peter Ueda of the Graduate School of Medicine, the University of Tokyo, shows that the number of people without children has nearly tripled nationwide over the past 30 years. rice field.
The Department of International Health Policy uses the National Institute of Population and Social Security Research's Basic Survey on Birth Trends to find out how many children were born between 1943 and 1948 and between 1971 and 1975 at the age of 40. We analyzed by income, educational background, gender, etc.
According to the report, 1943% of men born between 1948 and 14.3, 1971% were born between 1975 and 39.9, 1943% of women were born between 1948 and 11.6, and 1971% were born between 1975 and 27.6.It became clear that both men and women have nearly tripled.The number of children increased by only one, while the number of children with two or more decreased.
Analyzing educational background, income and the number of children, the higher the income, the fewer men had no children at any time. Except for those born between 1943 and 1947, those with a college degree or above were more likely to have children.On the other hand, when women were born between 1956 and 1970, the percentage of university graduates who had children was smaller than that of other educational backgrounds, but when they were born after 1971, there was a difference in educational background and the number of children. It's gone.
The declining birthrate has caused a serious population decline in Japanese society, and has emerged as a cause of various problems such as stagnation of economic activities and the disappearance of regions.However, there were many unclear points about the background, and it was not clear what kind of influence the educational background and income had.
