Is a common phenomenon. Generally speaking, the more developed countries and regions, such as Singapore, Japan and China's first tier cities, the higher the education level, the lower the fertility rate. It is recognized by experts and scholars all over the world that the education level is negatively related to the number of children born by women, and countless studies and papers have reached the same conclusion.

The main reasons are as follows:

Women with high academic qualifications generally have better jobs, higher salaries and stronger enterprise. Childbirth and children are too young to live without people. One to n years will delay the cause, and it will be difficult to remedy it later. The better the job, the greater the opportunity cost.

Women with high academic qualifications are generally more assertive. They are not confused about having children at home, or seeing that their peers will have children, but they are more stable and will weigh the pros and cons before making a decision. This trade-off has found many negative effects of having children.

Women with high academic qualifications will collect and sort out information, which is an essential skill for writing papers and doing research. Many women with low academic qualifications may have no idea of risks and consequences before giving birth, while women with high academic qualifications have thought of and discovered them in advance. Therefore, when weighing the advantages and disadvantages, the disadvantages of highly educated women are even heavier.

In general, the higher the social status and money status, the less likely children are to surpass themselves, and the situation that each generation is stronger than the next will become less and less. A child born in an uneducated rural area is likely to have more prospects than himself, so the concept of raising children to prevent old age is very common. Couples with high education and high salary are unlikely to produce better children, and it takes a lot of energy and financial resources, so some people think that investing in children is not as good as investing in themselves. Of course, except those who like children regardless of cost performance, most children are born for love, not for reward.

To a large extent, women with high academic qualifications and high salaries will have more confidence and voice, and will not be influenced by their parents' in-laws and seven aunts. Imagine a female worker with a monthly salary of 2000 yuan and a white-collar worker with a monthly salary of 20 thousand yuan. Who is more emboldened to refuse in the face of her husband's family?

It is precisely because of the high salary that highly educated women can have their own plans for providing for the aged. For example, they can save the cost of senior nursing homes in advance without worrying about their old age. And a pair of low-income couples, moonlight every month, don't even have old-age insurance, and having (a few) children to support the elderly has become the only way out.

Generally speaking, highly educated women's spouses are not low in education, and highly educated men are more likely to be open-minded, respect their wives and not be at the mercy of their families. Even many highly educated men don't want children than their wives.

Highly educated women generally choose to settle in big cities, which are more progressive in thinking and more receptive to unmarried or dink than rural areas or county towns, so the pressure of public opinion in the big environment is not so great, and it is easier to keep their wishes.
