In this return appearance on the podcast, demographer Lyman Stone joins Aaron Renn to discuss the latest global fertility and marriage trends as of 2026. While U.S. birth rates and marriage rates have shown relative stability at low levels, the picture elsewhere is far bleaker—sharp declines in East Asia and Eastern Europe, with South Korea hitting historic lows.

They explore the long-term consequences: aging societies, loss of dynamism, military vulnerabilities, and whether the United States could emerge as demographic "last man standing" in a world of collapsing birth rates. The conversation covers housing affordability, young men's declining economic prospects, marriage penalties in public policy, ineffective pronatalist interventions, and why cash incentives do work—but at a steep price. Stone also critiques "billionaire baby fetishes," calls for fixing marriage disincentives, and highlights practical ideas like family-friendly airports and better child tax credit design.
