World Underpopulation Problem

Some statistics suggesting that the Earth’s population might not continue to increase indefinitely.

I’m not sure how reliable this information (referenced by the thread) is, but it is interesting:

The 2050 projection has gone from the 1994 estimate of 9.8 billion to this year’s [1998] estimate of 8.9 billion.

Over the past 30 years, the average number of children born to women in the less-developed countries has fallen from 6.2 to 3.0—a decline of record-breaking speed.

Although a fertility rate of 2.1 children per woman is needed just to replace current population, in Europe the fertility rate has dropped to 1.42 and in Japan to 1.43.

This would support the idea that increasing quality of life will eventually rein in global population growth.

Edit: NYT article: “Demographic ‘Bomb’ May Only Go ‘Pop!’”

More surviving children means less incentive to give birth as often. As late as 1970, the world’s median fertility level was 5.4 births per woman; in 2000, it was 2.9. Barring war, famine, epidemic or disaster, a country needs a birthrate of 2.1 children per woman to hold steady.
