When might we run out of kids?

More than you wanted to know about the fertility crisis

Excerpt: "I’m not a population expert, but there’s a ticking time bomb. Almost everywhere in the world, pretty much without exception, has lower birth rates than they used to. In fact, most of the world is below replacement (TFR of 2.2 or 2.1, depending on where you live).

This is true in the US. In Europe. In Australia. Singapore. Japan. Korea. It’s reducing even in India, South East Asia, Latin America. It’s quite possible that despite the heroic efforts from Africa, we might be at replacement TFR insofar as the world is concerned right now.

And this is likely to continue. Today’s <15 set guarantees rising absolute births through ~2040 even if TFR = 1.7, but the trend is rather clear, just looking at the above numbers. Depending on which numbers you believe people think the global population will peak at like 9-10 Billion in the 2050s, then start dropping."
