The post below is probably going to elicit a lot of comments. Some of it will repeat chestnuts of historical wisdom which illustrate the ignorance of the typical modern. For example, it is false that the lower classes always have more children than the upper classes. In general it is the reverse, because the lower orders are more squeezed on the Malthusian margins (this explains how downward social mobility worked in early modern Europe; the less successful children of the elites drifted down to replace the masses who were not replacing themselves). In any case, Angela M. Cable asks:
Has it not occurred to anyone that perhaps the more educated a woman is, the less she *wants* children. How do we know these women are not child-free as opposed to child-less?
If I was Angela I would go look for the literature on this. I'm not one to ask questions imperiously without taking the time out to actually do some legwork. But I'm a peculiar beast. Let's satisfy Ms. Cable's curiosity, which probably remains unsated by any compulsion to find out the truth of the matter. The General Social Survey has a variable which asks the ideal number of children an individual would like to have. Let's replicate the analysis with that variable, and look at the difference between ideal and realized number of children.
Some of the difference has to be the fact that more educated women have children later. So they'll get closer to their "goal." But I don't think all of it is due to that. Interestingly the variation in the ideal number of children is smaller than that of the realized number of children. That suggests that the gap between educated and uneducated isn't simply an ideological preference chasm.
