Overpopulation Isn't The Problem: It's Too Few Babies

The world’s population recently passed the 7 billion mark, and, of course, the news was greeted with hysteria and consternation in the media. “It’s not hard to be alarmed,” intoned National Geographic. “We should all be afraid, very afraid,” warned the Guardian.

To be sure, continued population increases, particularly in very poor countries, do threaten the world economy and environment — not to mention these countries’ own people. But overall the biggest demographic problem stems not from too many people but from too few babies.

This is no longer just a phenomenon in advanced countries. The global “birth dearth” has spread to developing nations as well. Nearly one-third of the 59 countries with “sub-replacement” fertility rates — those under 2.1 per woman — come from the ranks of developing countries. Several large and important emerging countries, including Iran, Brazil and China, have birthrates lower than the U.S.

In the short run this is good news. It gives these countries an opportunity to leverage their large, youthful workforce and declining percentage of children to drive economic growth. But over the next two or three decades — by 2030 in China’s case – these economies will be forced to care for growing numbers of elderly and shrinking workforces. For the next generation of Chinese leaders, Deng Xiaoping’s rightful concern about overpopulation at the end of the Mao era will shift into a future of eldercare costs, shrinking domestic markets and labor shortages. the rest
Of course, there have always been unmarried people and childless people; some by necessity or health reasons, others by choice. But now a growing proportion of young child-bearing age women in countries as diverse as Italy, Japan and Taiwan are claiming no intention of having even one child. One-third of Japanese women in their 30s are unmarried, and similar trends are developing in other Asian countries.
