美国20-39名妇女的无子女率急剧上升,2024年,由于成本、职业和社会变化,无子女妇女人数比预期增加570万。 U.S. childlessness among women 20–39 rose sharply, with 5.7 million more childless women in 2024 than expected, driven by cost, career, and social changes.

新罕布什尔大学的一项新研究发现,美国20至39岁妇女的无子女率大幅上升,2024年无子女妇女人数比预期增加570万,比2016年增加210万。 A new study from the University of New Hampshire finds a significant rise in childlessness among U.S. women aged 20 to 39, with 5.7 million more childless women in 2024 than expected—up from 2.1 million in 2016. 17年来,由于30岁以下妇女的生育率下降,出生人数比预计的少近1 200万。 Over 17 years, nearly 12 million fewer births occurred than projected, driven by declining fertility among women under 30. 尽管老年妇女的生育率略有提高,但增长并未抵消下降。 Despite modest increases in fertility among older women, the gains didn’t offset the drop. 研究人员将这一趋势与住房和育儿费用的上升、儿童保育和家事假有限、婚姻率降低、妇女受教育和事业的机会增加等联系起来。 Researchers link the trend to rising housing and child-rearing costs, limited childcare and family leave, lower marriage rates, and greater educational and career opportunities for women. 这一转变引起了人们对保健、学校、工业和劳动力的长期影响的关切,这种现象被称为“人口悬崖 ” 。 这项研究基于人口普查和卫生统计数据,没有经过同行审查,也没有得到联邦和州来源的资助。 The shift raises concerns about long-term impacts on healthcare, schools, industries, and the labor force, a phenomenon called the “demographic cliff.” The study, based on Census and health statistics data, has not been peer-reviewed and was funded by federal and state sources.
