Should the government expand mortgage programs to encourage young people to start families?
The National Bureau of Economic Research published a study in September 2026 linking historic federal mortgage support to higher fertility rates during the mid-20th century. The findings suggest that when young families gained easier access to homeownership, birth rates climbed.
Why it matters
Researchers found that homeownership provided the financial and emotional security necessary for young families to plan for children. This historical connection provides context for how modern housing policy and current mortgage access influence the long-term financial choices of households.
For every 1,000 government-issued mortgages, there were 300 additional births the following year. While mortgage rates reached 7 percent in September 2026, the median age of first-time home buyers had climbed to 40 by 2025.
The players
National Bureau of Economic Research
A private, non-profit research organization that provides non-partisan economic data and analysis on U.S. trends.
Federal Reserve
The central bank of the United States that manages monetary policy and maintains mortgage records.
The details
Researchers digitized thousands of Federal Reserve records over two years to track how mortgage accessibility between 1940 and 1960 affected family planning. During this period, homeownership among childbearing-age Americans jumped from 20 percent to 50 percent, coinciding with a rise in the U.S. total fertility rate to 3.7 children per woman by 1957. Analysts note that today, mortgage assistance policies could potentially face different outcomes due to restricted housing supply and higher entry costs for first-time buyers.
Timeline
1940: Homeownership for childbearing-age adults was 20 percent.
1946: The U.S. baby boom began.
1957: The total fertility rate reached 3.7 children per woman.
1960: Homeownership for childbearing-age adults reached 50 percent.
September 2026: The National Bureau of Economic Research published its findings.
Money Landscape
This study revisits the economic conditions of the post-World War II baby boom to analyze the link between housing policy and family planning. It highlights a sharp contrast with the current climate, where the median age of first-time home buyers has reached 40.
Rising mortgage costs and high home prices remain significant barriers for families planning long-term financial milestones. Households should consult a qualified financial professional to review how current interest rates fit into their specific long-term budget and debt-management strategy.
The takeaway
Financial security provided by homeownership has historically served as a catalyst for major life milestones like childbearing. Families navigating current mortgage rates may benefit from reviewing their overall financial readiness with a qualified tax or financial professional.
