In an episode released in January 2025, Senior Editor Kanishk Tharoor spoke with the political economist Nicholas Eberstadt about the global crash in fertility rates and the looming prospect of depopulation.
Over the past century, the world’s population has exploded—surging from around one and a half billion people in 1900 to roughly eight billion today. But according to Eberstadt, that chapter of human history is over, and a new era, which he calls the age of depopulation, has begun. That subject has become even more prevalent in the past year. The United States, for example, recorded its lowest ever birthrate in 2024.
Eberstadt is the Henry Wendt Chair in Political Economy at the American Enterprise Institute and has written extensively on demographics, economic development, and international security. In a 2024 essay for Foreign Affairs, Eberstadt argued that plummeting fertility rates everywhere from the United States and Europe to India and China point to a new demographic order—one that will transform societies, economies, and geopolitics.
