Population Bomb? Or Population Dud?
Want to keep abreast of the important subjects of the day and prepare yourself for the leading topics that the mainstream media will soon be discussing? Then remember to listen to the Anchor Rising spot on the Matt Allen show on WPRO radio (630 AM) Wednesdays, around 6:50 pm; a few weeks ago, Matt and I discussed the problems with conventional, elitist Malthusian wisdom about population growth. This Sunday, the New York Times Magazine picked up on the same topic in a long article by Russell Shorto (h/t Instapundit)…
In the 1990s, European demographers began noticing a downward trend in population across the Continent and behind it a sharply falling birthrate. Non-number-crunchers largely ignored the information until a 2002 study by Italian, German and Spanish social scientists focused the data and gave policy makers across the European Union something to ponder. The figure of 2.1 is widely considered to be the “replacement rate” — the average number of births per woman that will maintain a country’s current population level. At various times in modern history — during war or famine — birthrates have fallen below the replacement rate, to “low” or “very low” levels. But Hans-Peter Kohler, José Antonio Ortega and Francesco Billari — the authors of the 2002 report — saw something new in the data. For the first time on record, birthrates in southern and Eastern Europe had dropped below 1.3. For the demographers, this number had a special mathematical portent. At that rate, a country’s population would be cut in half in 45 years, creating a falling-off-a-cliff effect from which it would be nearly impossible to recover. Kohler and his colleagues invented an ominous new term for the phenomenon: “lowest-low fertility.”The Times article proposes an explanation for observed population growth patterns sure to generate protests from the government-planning-is-always-best crowd…
To the uninitiated, “lowest low” seems a strange thing to worry about. A few decades ago we were getting “the population explosion” drilled into us. The invader species homo sapiens, we learned, was eating through the planet’s resources and irretrievably fouling and wrecking its fragile systems. Has the situation changed for the better since Paul Ehrlich set off the alarm in 1968 with his best seller “The Population Bomb”? Do current headlines — global food shortages, climate change — not indicate continuing signs of calamity?
They do, as far as some are concerned, but things have changed somewhat. For one thing, around the world, even in developing countries, birthrates have plummeted — from 6.0 globally in 1972 to 2.9 today — as populations have shifted from rural areas to cities and people have adopted urban lifestyles, and the drop has perhaps lessened the urgency of the overpopulation cry….
To many, “lowest low” is hard evidence of imminent disaster of unprecedented proportions. “The ability to plan the decision to have a child is of course a big success for society, and for women in particular,” Letizia Mencarini, a professor of demography at the University of Turin, told me. “But if you would read the documents of demographers 20 years ago, you would see that nobody foresaw that the fertility rate would go so low. In the 1960s, the overall fertility rate in Italy was around two children per couple. Now it is about 1.3, and for some towns in Italy it is less than 1. This is considered pathological.”
Last year the fertility rate in the United States hit 2.1, the highest it has been since the 1960s and higher than almost anywhere in the developed world. Factor in immigration and you have a nation that is far more than holding its own in terms of population. In 1984 the U.S. Census Bureau projected that in the year 2050 the U.S. population would be 309 million. In 2008 it’s already 304 million, and the new projection for 2050 is 420 million.
“Europeans say to me, How does the U.S. do it in this day and age?” says Carl Haub of the Population Reference Bureau in Washington. According to Haub and others, there is no single explanation for the relatively high U.S. fertility rate. The old conservative argument — that a traditional, working-husband-and-stay-at-home-wife family structure produces a healthy, growing population — doesn’t apply, either in the U.S. or anywhere else in the world today. Indeed, the societies most wedded to maintaining that traditional family structure seem to be those with the lowest birthrates. The antidote, in Western Europe, has been the welfare-state model, in which the state provides comprehensive support to couples that want to have children. But the U.S. runs counter to this. Some commentators explain its healthy birthrate in terms of the relatively conservative and religiously oriented nature of American society, which both encourages larger families. It’s also true that mores have evolved in the U.S. to the point where not only is it socially acceptable for fathers to be active participants in raising children, but it’s also often socially unacceptable for them to do otherwise.
But one other factor affecting the higher U.S. birthrate stands out in the minds of many observers. “There’s much less flexibility in the European system,” Haub says. “In Europe, both the society and the job market are more rigid.” There may be little state subsidy for child care in the U.S., and there is certainly nothing like the warm governmental nest that Norway feathers for fledgling families, but the American system seems to make up for it in other ways. As Hans-Peter Kohler of the University of Pennsylvania writes: “In general, women are deterred from having children when the economic cost — in the form of lower lifetime wages — is too high. Compared to other high-income countries, this cost is diminished by an American labor market that allows more flexible work hours and makes it easier to leave and then re-enter the labor force.” An American woman might choose to suspend her career for three or five years to raise a family, expecting to be able to resume working; that happens far less easily in Europe.
So there would seem to be two models for achieving higher fertility: the neosocialist Scandinavian system and the laissez-faire American one. Aassve put it to me this way: “You might say that in order to promote fertility, your society needs to be generous or flexible. The U.S. isn’t very generous, but it is flexible. Italy is not generous in terms of social services and it’s not flexible. There is also a social stigma in countries like Italy, where it is seen as less socially accepted for women with children to work. In the U.S., that is very accepted.”
