Source - Economist, November 24, 2018: "Baby bust"
The US birth rate has been falling and is more in line with European birth rates. The downward change is especially large in Hispanics and urban families.
All from the article: Soon after the great recession hit America, in 2007, the birth rate began to fall. Many people lost their jobs or their homes, which hardly put them in a procreative mood. But in the past few years the economy has bounced back—and births continue to drop. America’s total fertility rate, which can be thought of as the number of children the average woman will bear, has fallen from 2.12 to 1.77. It is now almost exactly the same as England’s rate, and well below that of France.
What changed? One possibility is that the drop is little more than a mathematical quirk. The total fertility rate is calculated by adding up the proportions of women in each year of life who had a baby in the previous year. It is affected by changes in birth timing. Suppose that all American women have exactly two children. If a cohort of women move to have those children later, the fertility rate will temporarily fall below two. This happened in the late 1970s, when the rate dipped to 1.74 before recovering.
To some extent, history is probably repeating itself. In 2017 the mean age of a first-time mother was 27, up from 25 in 2007. The teenage birth rate has halved in the past ten years—something that Power to Decide, a campaign group, attributes to less sex and better contraception. Colleen Murray, its senior science officer, says that Obamacare has made long-acting contraceptives like IUDs available to more young women. The trend of Americans giving birth at ever older ages could run for a while. In Europe, women’s mean age at first birth is 29. In Japan it is 31.
And with every passing year the drop in American fertility seems less temporary. Some data suggest that people have come to desire small families. The large National Survey of Family Growth shows that 48% of American women with one child expect not to have a second. Some religious conservatives fear that a broad cultural shift is under way. According to Gallup, a pollster, the share of Americans who never go to church has risen from 10% to 27% since 2000. That could be connected to falling fertility. Churches tend to be in favor of children—more so than the other places where people hang out on the weekend, such as gyms and bars. But it is hard to disentangle cause from effect. What is clearer is that America’s fertility rate is being pulled down by two specific groups of people: Hispanics and urbanites. Hispanic women still have more children, beginning at a younger age, than non-Hispanic whites, blacks or Asians. But their fertility rate is falling exceptionally quickly. Between 2007 and 2017 it dropped from three to two, pulling down the national average. William Frey, a demographer at the Brookings Institution, a think-tank, points out that the recession hit them hard. Many Hispanics worked in the construction business, which collapsed, and lost their own homes to foreclosure. Hispanics are also increasingly American. Two-thirds were born in the country, and the proportion is rising because immigration from Latin America has slumped. They have probably adopted American small-family norms. The fertility rate has fallen more sharply in large cities than in smaller cities or rural areas (see chart 2). Rents and prices have soared, making it harder to afford an extra bedroom. Lots of properties are being built in city centers—but many of these are tiny flats in towers. In 2006 only 27% of newly completed apartments had fewer than two bedrooms. In 2017 fully 48% did.
It is possible that cities like Miami are not only accommodating the growing ranks of single and childless people, but are actually creating more of them. Hill Kulu, a demographer at the University of St Andrews in Scotland, has found that in England and Finland suburbanites and small-town-dwellers have more children than you would expect from looking at other aspects of their lives. It is almost as though extra bedrooms and child-friendly neighborhoods make children. Perhaps the American family is becoming more European because its cities are looking a little denser and a little less suburban—that is, a little more European.
