Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.

The whole demographical transition to lower birthrates has a more detailed explanation in the theory that more educated women are much more choosy and (at least) less enthusiastic with bearing children with men of about equal status. UN data says that we just reached peak baby, with significant exception in Africa only, where prospects for improving status, the living standard or marrying up are still well believable.

So instead of children per woman decreasing evenly, you would have one group of women continuing having many children and another ot having any? Right?

Sounds totally off base to me, but it is a testable statement. Now go see if you can find data that supports your statement.

Why would you assume that "children per woman" would decrease somewhat evenly?

Comparing sizes of rich patriarchal families with families of highly successful women would be interesting  -- but I have choices on whom to work for. Is there any update on conservative versus liberal families?

In nature, females of hierarchical species typically do not reproduce evenly at all. What happens in the next 5 minutes in this video should not be surprising.

The new Oxford Handbook of Evolution, Biology, and Society is highly recommendable.

Evolution and Human Reproduction
Section "Social Status, Wealth, and Reproduction" is what we are talking about.

Evolution, Societal Sexism, and Universal Average Sex Differences in Cognition and Behavior

contrary to most scientists' expectations, these so-called universal sex differences have been shown to be more pronounced in Western industrial societies than in most non-Western developing societies
