According to Bloomberg News website on November 20th, an increasing number of American adults who have not yet become parents say they are likely not to have children, citing reasons such as lack of interest, financial instability, or lack of a partner. According to a report, a latest survey by the Pew Research Center found that 44% of Americans aged 18 to 49 who are not yet parents say they are unlikely or even unlikely to have children one day, an increase of 7 percentage points from 37% in 2018. The report also stated that the survey results do not bode well for reversing the trend of declining fertility rates in the United States. Due to the public health and economic crisis caused by the epidemic, the fertility rate in the United States has been severely affected. According to a report from the Centers for Disease Control and Prevention in the United States, the number of babies born in the United States decreased by 4% to around 3.6 million in 2020. According to the report, about 1/4 of adults under 40 who are already parents do not want more children due to related economic costs, while 3/10 of people say they do not want more children because they are too old.
