Could Homeownership Reverse the Decline in Birthrates?

Puzzling over the reasons for today's baby bust, economists Melissa S. Kearney and Lisa J. Dettling looked to the last baby boom for answers. Published by the National Bureau of Economic Research, their study finds a strong economic connection between homeownership and birth rates, challenging the view that personal finances are secondary to family planning. The researchers discovered that government-backed home mortgages, particularly those issued under the postwar G.I. Bill, played a transformational role. Among Americans of childbearing age, homeownership rose to 50 percent in 1960, from 20 percent in 1940. For every 1,000 new mortgages issued through government programs, there were about 300 additional births the following year. The findings suggest that housing security, not just income, influences the decision to have children. As housing costs rise and the median age of first-time buyers hits a historic high of 40, the study offers insights into policies that could reverse historic lows in fertility. Governments have tried tax credits and subsidized child care, but the research points to housing policy as a potent lever for encouraging family formation.

The Baby Boom began in 1946 after World War II. By 1957, the total fertility rate reached 3.7 children per woman. While previous hypotheses focused on economic security and reduced health risks, Kearney and Dettling examined the expansion of homeownership. The G.I. Bill gave millions of returning soldiers the ability to buy houses with low or no down payments, helping build the American middle class. Young families benefited most, with homeownership rising significantly among childbearing-age Americans. Researchers linked digitized mortgage records with demographic data to test the effect, finding a startling correlation between mortgage issuance and subsequent birth rates.

在探究当今生育率下降的原因时，经济学家梅丽莎·S·基尔尼（Melissa S. Kearney）和丽莎·J·德特林（Lisa J. Dettling）将目光投向了过去的婴儿潮，以寻求答案。这项由美国国家经济研究局（National Bureau of Economic Research）发表的研究发现，拥有住房与出生率之间存在强烈的经济联系，挑战了个人财务状况在家庭规划中属于次要因素的观点。研究人员发现，政府支持的住房抵押贷款，尤其是战后《退伍军人权利法案》（G.I. Bill）下发放的贷款，起到了变革性的作用。在育龄的美国人中，拥有住房的比例从1940年的20%上升到1960年的50%。通过政府项目每发放1000笔新贷款，次年就会增加约300名新生儿。这些发现表明，住房保障——而不仅仅是收入——影响着生育决策。随着住房成本上升和首次购房者的中位年龄达到40岁的历史高位，这项研究为可逆转生育率历史性低谷的政策提供了洞见。政府已尝试通过税收抵免和补贴育儿服务来应对，但研究表明，住房政策才是鼓励家庭形成的有力杠杆。

婴儿潮始于1946年第二次世界大战之后。到1957年，总生育率达到每位女性3.7个孩子。尽管此前的假设集中在经济安全和健康风险降低上，基尔尼和德特林却考察了拥有住房的扩张。《退伍军人权利法案》使数百万归国士兵能够以低首付或无首付购买房屋，帮助建立了美国中产阶级。年轻家庭受益最大，育龄美国人的拥有住房比例显著上升。研究人员将数字化抵押贷款记录与人口数据进行关联，以检验其影响，发现抵押贷款发放量与随后出生率之间存在惊人的相关性。

FAQ Q: 基尔尼和德特林发现哪种政策能有效提高出生率？

FAQ A: 政府支持的住房抵押贷款，尤其是战后《退伍军人权利法案》下发放的贷款，被发现能显著提高出生率，每1000笔新贷款与次年约300名额外出生相关。
