The following industries may be affected by the decline in the number of births:

1. Education: The decline in the number of births may lead to a decrease in school and university enrollment, which may affect the demand for employment in the education industry. Schools and educational institutions may need to adjust their enrollment plans and resource allocation.

2. Children's Goods and Services Sector: A declining birthrate will have a direct impact on the children's goods and services sector, such as children's toys, baby products, and children's apparel. These industries may face the pressure of declining market demand.

3. Medical and Nursing Sectors: With the decline in births, the demand for pediatricians and nurses may decrease as the demand for pediatric medical services will decrease accordingly.

4. The real estate industry: fewer births may lead to smaller families, with fewer families needing to buy homes and rent, which could have an impact on the real estate market.

5. Food and restaurant industry: fewer births may reduce the demand for children's meals and children's food, which may have a negative impact on the food and restaurant industry.

It is important to note that the decline in births will not only affect some specific industries, but may also have a ripple effect on the economy as a whole. It could lead to an insufficient supply of human resources, reducing competition and innovation in the labor market, with potentially negative impacts on economic growth.
