The Age of Depopulation With Nicholas Eberstadt | Peter Robinson | Uncommon Knowledge

September 12, 2025·55 min·5 clips

Demographer Nicholas Eberstadt reveals global population will decline for the first time since the bubonic plague.

The interview begins with an alarm. Robinson introduces Eberstadt as a political economist trained at Harvard and an American Enterprise Institute fellow who studies global depopulation. The setup is intentionally historical. Eberstadt's Foreign Affairs article gives the conversation its backbone: humanity may be heading into population decline for the first time since the Black Death. Robinson asks for the broad map and says they will take the subject continent by continent. The liveliest turn is about imitation. Eberstadt argues that fertility behavior is shaped by what people see around them, not only by private preference or economic incentives. He calls that social learning. Mary Eberstadt's cat stuck in a tree example works as a small parable about knowledge that disappears when no one nearby still knows how to model it. Large families, in this telling, are a learned practice. Eberstadt says economists are trained to treat the desire for children as exogenous, but he doubts societies can easily climb back to replacement fertility once they fall far below it. The loss may stick. Robinson tries the idea through his own analogy, comparing abundant childrearing to Latin after ordinary use has vanished. Eberstadt accepts the point, with care. He then points to Israel as a striking exception, where even secular Jews reportedly remain above replacement fertility. Modernity does not look the same everywhere. That example gives the interview its bite. This is not only a conversation about falling numbers. It is about whether cultures can keep reasons for having children alive. The ending turns spiritual, with Eberstadt expecting adaptation, meaning-making, and spiritual ferment as populations shrink, while Robinson closes in the show's formal institutional style.

As heard by us

A sober argument that population decline is a cultural story before it is a statistical one.

Nicholas Eberstadt argues, with real force, that the world may be moving into depopulation for the first time since the bubonic plague, and Peter Robinson lets the case unfold continent by continent.
