The Global Baby Bust : short term benefits for the WOT, long term costs
Excerpted from a loooong article in Foreign Affairs Magazine. Hattip Instapundit. Lots of meat, and concisely written. The writer is very worried about the long term situation, but I read it that those who have faith in the future will end up inheriting the earth through their grandchildren, even if there will be pain for a while. ;-) Read the whole thing.Summary: Most people think overpopulation is one of the worst dangers facing the globe. In fact, the opposite is true. As countries get richer, their populations age and their birthrates plummet. And this is not just a problem of rich countries: the developing world is also getting older fast..... [A] closer look at demographic trends shows that the rate of world population growth has fallen by more than 40 percent since the late 1960s. And forecasts by the UN and other organizations show that, even in the absence of major wars or pandemics, the number of human beings on the planet could well start to decline within the lifetime of today's children. Demographers at the International Institute for Applied Systems Analysis predict that human population will peak (at 9 billion) by 2070 and then start to contract. Long before then, many nations will shrink in absolute size, and the average age of the world's citizens will shoot up dramatically. Moreover, the populations that will age fastest are in the Middle East and other underdeveloped regions. During the remainder of this century, even sub-Saharan Africa will likely grow older than Europe is today. The root cause of these trends is falling birthrates. Today, the average woman in the world bears half as many children as did her counterpart in 1972. No industrialized country still produces enough children to sustain its population over time, or to prevent rapid population aging. Germany could easily lose the equivalent of the current population of what was once East Germany over the next half-century. Russia's population is already contracting by three-quarters of a million a year. Japan's population, meanwhile, is expected to peak as early as 2005, and then to fall by as much as one-third over the next 50 years -- a decline equivalent, the demographer Hideo Ibe has noted, to that experienced in medieval Europe during the plague. Although many factors are at work, the changing economics of family life is the prime factor in discouraging childbearing. In nations rich and poor, under all forms of government, as more and more of the world's population moves to urban areas in which children offer little or no economic reward to their parents, and as women acquire economic opportunities and reproductive control, the social and financial costs of childbearing continue to rise.... Today, when Americans think of Mexico, for example, they think of televised images of desperate, unemployed youths swimming the Rio Grande or slipping through border fences. Yet because Mexican fertility rates have dropped so dramatically, the country is now aging five times faster than is the United States. It took 50 years for the American median age to rise just five years, from 30 to 35. By contrast, between 2000 and 2050, Mexico's median age, according to UN projections, will increase by 20 years, leaving half the population over 42. Meanwhile, the median American age in 2050 is expected to be 39.7. Those televised images of desperate, unemployed youth broadcast from the Middle East create a similarly misleading impression. Fertility rates are falling faster in the Middle East than anywhere else on earth, and as a result, the region's population is aging at an unprecedented rate. For example, by mid-century, Algeria will see its median age increase from 21.7 to 40, according to UN projections. Postrevolutionary Iran has seen its fertility rate plummet by nearly two-thirds and will accordingly have more seniors than children by 2030.... Over the next decade, the Middle East could benefit from a similar "demographic dividend." Birthrates fell in every single Middle Eastern country during the 1990s, often dramatically. The resulting "middle aging" of the region will lower the overall dependency ratio over the next 10 to 20 years, freeing up more resources for infrastructure and industrial development. The appeal of radicalism could also diminish as young adults make up less of the population and Middle Eastern societies become increasingly dominated by middle-aged people concerned with such practical issues as health care and retirement savings. Just as population aging in the West during the 1980s was accompanied by the disappearance of youthful indigenous terrorist groups such as the Red Brigades and the Weather Underground, falling birthrates in the Middle East could well produce societies far less prone to political violence.... Even if the United States could compete with Europe for immigrants, it is by no means clear how many potential immigrants these regions will produce in the future. Birthrates are falling in sub-Saharan Africa as well as in the rest of the world, and war and disease have made mortality rates there extraordinarily high. UN projections for the continent as a whole show fertility declining to 2.4 children per woman by mid-century, which may well be below replacement levels if mortality does not dramatically improve. Although the course of the AIDS epidemic through sub-Saharan Africa remains uncertain, the CIA projects that AIDS and related diseases could kill as many as a quarter of the region's inhabitants by 2010. The writer also talks about how with increased social welfare costs of aging populations, nations will not be able to afford armies or wars, not even the US, so there'll be no more wars. Less innovation from oldster-heavy populations as well, so no increase in productivity from the remaining youngsters, and no discussion of the impact of a Bird Flu or other pandemic. My personal view on the army thing is that, at least in the Anglosphere and Israel, while the median age of the troops will increase, there will be no lack of those willing to serve. I wouldn't have thought so before I started hanging out here, but now I know that old sheepdogs never really stop standing guard. I'm not as worried about the innovation thing either -- my father discovered interferon just before being pushed into retirement, which meant the world had to wait another decade before someone else came up with it (and got the cover of Time Magazine and all the other rewards as a result -- Daddy was *not* happy about that, poor man). In a culture that rewards innovation, innovative people don't stop just because the clock turns over. Posted by: trailing wife 2006-05-12 |
