The world is running out of children.
This project covers the most important demographic story of our lifetime, with the calm and rigor it deserves.
Global TFR (total fertility rate) is around 2.24 and falling fast. The US hit a record low of 1.599 in 2024. South Korea is at 0.72, the lowest of any country ever recorded in peacetime. About 71% of humanity now lives in countries below replacement. The Lancet projects that by 2100, 97% of countries will be there too.
This is genuinely new in human history. Every previous fertility decline was either temporary or reversed. This one shows no signs of reversing in any country that has lived with it for twenty years.
The lane we're in
We take Hannah Ritchie's posture toward climate data, Tim Urban's patience with hard ideas, and Kurzgesagt's commitment to getting the numbers right, and we apply all three to falling birthrates.
The goal: explain this clearly, source every claim, and keep the politics out of it.
What we don't do
- Doom-mongering or collapse-porn
- Manosphere framing
- Tribal pronatalism
- Culture-war takes on environmentalism
- "Wake up" energy as a primary mode
The trademark frame
The UN's 2025 survey across 14 countries found that people, on average, say they want about 2 children and are having about 1.4. That 0.6-child gap between desire and reality is the most under-amplified fact in the entire conversation. Reframe everything around that number and the question changes. It goes from "should people have more kids" (a culture-war fight nobody wins) to "why aren't people having the kids they say they want" (a problem-solving frame).
