The headline news of a study of women sociologists is that having children does not interfere with having a successful career at a research university.
What struck me about the study by Roberta Spalter-Roth and Nicole Van Vooren, though, is the even larger difference that having kids made to the careers of men.
The study divided these sociology Ph.D.s, measured a decade after getting their degree, into "ideal" careers as tenured professors at research universities, "alternative" careers as tenured professors at teaching colleges, or "marginal" careers as adjunct teachers and the like.
For the fathers, 80% were in either ideal or alternative positions, with only 20% getting by marginally.
For childless men, 41% were in marginal careers.
I see this is further evidence that marriage and fatherhood transforms men from the least productive to the most productive workers.
