The right does a tolerable job beefing about and critiquing the problems with left/liberal hysteria about “too much” fertility. But they conflate two issues into one and thus come out unsuccessful in their rhetorical quest to get married women to pop out more babies.
The fact is that American white fertility has been clustered around 2-4 children (with 5-6 the acceptable fringe due to Catholic and Mormon influences) since basically we had free black people and free white people (so, since 1870 or so). American black fertility has been more like 2-6 children until the 1970s, when they pretty much went to the same pattern as whites. There were also extended periods where both black and white women had 20% or so rates of no children.
So fixating on 1950s style fertility, with its unusually low rate of childlessness among the women of both races, is historically inaccurate. The excessive and vigorous rhetoric on even the mainstream right regarding family size is not very successful because it’s going up against long-standing American norms about family size being relatively small even when there wasn’t much or any modern birth control.
And it causes the right to make that conflation error I led with. They look at small family sizes through a 1950s, historically wrong lens, and declare, repeatedly, that college education is responsible, whether it’s simply attending at all (non-mainstream right) or liberal indoctrination while attending plus too many people attending (mainstream right).
Which brings us to the College Funnel. The College Funnel is the process by which married childbearing increasingly requires women to climb into the College Funnel and squeeze their way through to a degree. Some, quite a few, fall out at various points, but even that much makes getting married before the kids come a whole lot more likely.
With whites, the College Funnel has clearly increased births for women attending and especially completing college. But the births for white women without college attendance have plunged dramatically. With blacks, the College Funnel is at least partly another way to describe married black birth becoming the province of educated immigrants and/or mixed marriages (racially or ethnically, as in marrying a black immigrant) at higher and higher rates since the 1980s. What you have left over in both white and black cases is a small hard core of annual unwed births that combined were around 400k in 1970 and are now around 900k-1m annually since 1990. Sharp rise, then flattened out.
The College Funnel is fairly raceless, with more racial and ethnic intermarriage, which probably muddies the numbers some too.
So you have this problem where people of a certain level of brains are having the married kids and in the case of whites and Asians, it’s most of their kids on top. You have this different problem where people who might or might not have that level of brains, but don’t get into the College Funnel basically can’t have kids except in a handful of “wheeee feckless pride” areas, mostly urban. And the second problem is real, and worth discussing. But combining it with the college thing and declaring college renders anyone who stands next to one sterile is incorrect and not a solid way to get to solutions to let those second-problem people get to have children, much less children mostly in wedlock, again.
The numbers are from data in the National Center for Health Statistics Vital Statistics Reports’ various pdfs.
