Research on China's Birth Rate based on BP Neural Network

Abstract

In terms of the impact of population age structure on birth rate, some studies have shown that compared to the reference category of respondents aged 30-34, young respondents are less likely to not have children, while older recipients have a more common unwillingness to have children; Women of childbearing age consider their own physical condition and reproductive safety factors. The older their parents are, the lower their willingness to have children, and after having one child, they may not be willing to have a second child; Moreover, if there are more elderly people in the family and the social pension security system and system are not perfect, the willingness of the family to have more children will decrease.
