Here’s a startling fact: America’s birth rates are plummeting, and the culprit isn’t just economic uncertainty or shifting cultural norms—it’s the skyrocketing cost of housing. But here’s where it gets controversial: new research suggests that if housing costs had remained stable since 1990, the U.S. could have seen 13 million more children born by 2020. Yes, you read that right. According to Benjamin K. Couillard, a doctoral candidate in economics at the University of Toronto, the link between housing costs and fertility rates is far more profound than most people realize. His preprint research paper reveals that rising housing costs have led to an 11% drop in births nationwide since 1990, with housing accounting for a staggering 51% of the total fertility decline between the 2000s and 2010s.
The U.S. fertility rate currently sits at 1.62 children per woman, well below the 2.1 replacement rate needed to maintain population stability, as reported by the National Center for Health Statistics. Couillard’s model, which combines urban economics and industrial organization, isolates the impact of housing costs from other factors influencing family planning and location choices. And this is the part most people miss: it’s not just about affordability—it’s about long-term demographic sustainability. If families can’t afford larger homes, they’re less likely to have more children, creating a ripple effect that could reshape the nation’s future.
Here’s the kicker: current U.S. housing policies focus heavily on building smaller units like studios and one-bedroom condos, which do little to address the needs of growing families. Professor Nathanial Baum-Snow, Couillard’s thesis supervisor, points out that subsidizing larger, family-sized homes would have a far greater demographic impact. In other words, families would have more children if they had the space to raise them comfortably. But here’s the controversial question: Are policymakers prioritizing short-term housing solutions over the long-term health of our population? Couillard argues that a maximalist housing policy—one that aggressively expands supply to keep costs down—could have solved the majority of the fertility problem.
So, what does this mean for the future? If housing costs continue to rise, the U.S. could face even more severe demographic challenges, from an aging population to labor shortages. Here’s where you come in: Do you think housing affordability should be a top priority for policymakers? Or is the focus on smaller units the right approach? Let’s spark a conversation—because this isn’t just about houses; it’s about the future of families and the nation as a whole.
