The trend of childlessness in Taiwan is getting more and more serious and has become a national security issue. In order to increase the desire to have children, the government has initiated various incentives to encourage births, including birth subsidies, childcare subsidies, and even marriage subsidies. According to statistics from the Ministry of the Interior, there will only be 165,249 newborns in Taiwan in 2020, a record low, but the number of deaths will exceed the number of births for the first time, the first time that the population has experienced negative growth, of which the public's late marriage and non-marriage is one of the key factors, as late marriage makes it difficult for women of childbearing age to give birth to their first child as the age of birth is being delayed year by year and it is hard to push for the birth of a second child. In addition, the heavy burden on child-rearing families and women's difficulties in combining family and employment also affect the desire to have children.
