Which industries are directly affected after the birth population is reduced?

The decline in the birth population may have an impact on the following industries:

1. Education industry: The decrease in the birth population may lead to a decrease in the number of students enrolled in schools and universities, thus affecting the employment demand of the education industry. Schools and educational institutions may need to adjust enrollment plans and resource allocation.

2. Children's products and services industry: The decrease of the birth population will directly affect the children's products and services industry, such as children's toys, baby products, children's clothing and so on. These industries may face the pressure of declining market demand.

3. Medical care industry: With the decrease of the birth population, the demand for pediatricians and nurses may decrease, because the demand for children's medical services will also decrease accordingly.

4. Real estate industry: The decrease of birth population may lead to the decrease of family size and the decrease of the number of families who need to buy houses and rent houses, thus having an impact on the real estate market.

5. Food and catering industry: The reduction of the birth population may reduce the demand for children's catering and children's food, which may have a negative impact on the food and catering industry.

It should be noted that the reduction of the birth population will not only affect some specific industries, but also affect the whole economy. It may lead to insufficient supply of human resources, reduce the competitiveness and innovation ability of the labor market, and have a potential negative impact on economic growth.
