As a result of a group such as the University of Tokyo analyzing the relationship between whether or not there are children and annual income for people in their late 40s to 70s, the proportion of people with children tends to increase as the annual income increases. I found out.
This research was conducted by a group of specially appointed researchers, Haruka Sakamoto, Graduate School of Medicine, the University of Tokyo.
Based on the national birth trend basic survey, the group analyzed the relationship between the annual income at the time of 40s and the number of children for people aged 47 to 79.
As a result, among men in the generation around 50 years old, the percentage of those who have children was 37% with an annual income of less than 3 million yen, while it was 80% with an annual income of 6 million yen or more.
At present, 74% of men in their late 70s have an annual income of less than 3 million yen, and 93% have an annual income of 6 million yen or more. In both cases, the higher the annual income, the higher the proportion of children.
On the other hand, the average number of children per child decreased as the generation became younger, but when analyzed by educational background, only women who graduated from college at around 50 years old are now higher than the older generation. The group says that economically independent women may be more likely to have children.
Researcher Sakamoto says, "We need to take measures to stabilize our lives, such as securing an employment environment, without considering the declining birthrate as a change in the values of young people."
