Fewer births, also known as low fertility rate or low fertility rate, refers to the phenomenon that the fertility rate in a region or country drops significantly, leading to a slowdown or even negative population growth. Fewer children are usually accompanied by a series of social, economic and political problems, such as labor shortage, increasing social security pressure and slowing economic growth.

There are many reasons for the decline in the birth rate, including the following aspects:

1. Economic development: With the economic development and industrialization, people's lifestyles and values have also changed. More and more people choose to pursue career development, personal freedom and quality of life, thus delaying or giving up childbirth.

2. Education level: The improvement of education level makes people pay more attention to the realization of their own values and career development, and at the same time makes people pay more attention to their children's education quality and growth environment, thus reducing their willingness to have children to some extent.

3. Urbanization: With the acceleration of urbanization, the pace of people's life is accelerating and the pressure of life is increasing, making it difficult for people to bear the responsibility of bearing and raising children.

4. Fertility policy: The government's fertility policy and related welfare measures will also have an impact on people's fertility wishes. If the government's birth policy is too strict or unattractive, it may lead people to postpone or give up giving birth.

The phenomenon of declining birthrate not only affects individuals, families and society, but also may have a far-reaching impact on the long-term development of a country. Therefore, many governments have adopted a series of policies and measures to deal with the problem of declining birth rate, such as increasing maternity allowance, expanding parental leave and improving medical and educational security.
