Economic Demography

The most robust trend in economic demography might also be one of the least publicized: rapid economic growth follows when the fertility rate falls below about 2.5. China and India illustrate the point. Go to Gapminder and compare total fertility and per capita gdp through time. In 1950, both had total fertility rates around 6 (with India slightly lower) and both were very poor 418 UX for China, 538 for India inflation adjusted dollars. Sometime during 1978, China caught up and passed India, each country now making about 800 per yr. But China's fertility rate was now 2.8 while India's was 4.6.

What happened next was dramatic. China's fertility rate dropped to 1.7 and China grew explosively, sextupling it's gdp per capita to 4959. India's fertility rate dropped too, but much more slowly and only to 2.5, and its gdp grew only half as much, to 2452.

These are the biggest guys on the block, but other have similar results. South Korea has grown steadily, but very rapidly since getting below the magic 2.0 number. Macau is atypical, but it to grew exposively after its fertility went all the way down below 1.

India and China are among the world's most productive lands but agriculturally and intellectually, so why are their people so poor? There is more than one reason, I'm sure, but the one that impresses me is that they just have way too many people.

Asia shows strong signs of clawing its way out of the Malthusian trap, but sub-equitorial Africa seems hopelessly trapped. It wouldn't hurt if more of the world would just acknowledge that we know the way out. Technology, infrastructure, and a economic legal system, sure, but the for the payoff -> fertility.

UPDATE: Why does **** stupid blogger insist on interpreting dollar signs as some sort of escape character? This post was incoherent enough without that.
