The big rise in childlessness happened two decades ago

(Pew Research Center)

The Pew report was confusingly presented. In spite of its title, that report included this illustration, indicating that the rate of childlessness was actually down in the last year of the study from the year prior, though it was definitely up from 1976.

The biggest rise in childlessness since 1976 (a 5 percent increase) occurred between 1984 and 1992, not exactly current news. There has been a rolling rise since then, but not a big one, and in 2008 the trend was down. The possibility that childlessness rose during the recession is real, but we await further updates.

The 10 percent rate in 1976 was anomalous

It’s worth noting that the childlessness rate has been higher than 10 percent at most points in U.S. history for which records exist. It ranged between 15 percent and 25 percent of white women [the majority and the group on which 19th century records were kept] born between 1830 and 1920—including women whose fertile years occurred during the Depression. And yes, many married couples during that era employed birth control, including condoms and diaphragms,—Goodyear patented the vulcanization of rubber in 1843—as well as withdrawal and abstinence. Per one study, the rate was 10 percent or below among white women only for those born between 1922 and 1942.

Women ages 40 to 44 are not all through with fertility

This data is also complicated by the fact that the pool of women tracked in this chart (women ages 40 to 44) have not all reached the end of their childbearing years. Some of those included in the “childless” count here will bear children by the usual means before they reach 44, the age at which fertility ends for pretty much everyone (exceptions occur but are few). This is a relatively small number—108,920 women between 40 and 44 had kids in 2011, of whom 24,246 were having a first child (and thus moving out of the set with no children). Given the widespread pattern of delaying kids, it’s also more likely that more women will be trying to get pregnant in this age group than did in the past, and so more will succeed.

More people are having kids after 45

Then there’s the new world of fertility technology: currently only a small number of women older than 45 have kids—we can assume that pretty much all of them occur via egg donation (7,610 in 2011, with 2,065 of those being first births, according to the CDC). But if substantial numbers of women are pushed past their natural fertility window by economic pressures, the possibility exists that we’ll see a rise in egg donor births once people are convinced the economic climate is positive and stable. Lowered cost, greater acceptance or other factors could also move more women to try this route.

The stats do not include adoption

The picture of childlessness is also blurred in that only biological parents are counted in the Pew and CDC reports. Both the CDC and the Pew data report on the numbers of women who did or did not bear children. But many adoptive parents—about 125,000 per year overall—would disagree if you called them childless. Add in step-parents and foster parents, and you have a bigger chorus. Given that the Time article focused on people without any kids in their homes, we can assume that many readers don’t see the discussion of childlessness on the same terms that demographers do.
