Many such studies are hobbled by small sample groups, or are too short term. The most extensive study to date, published in February in the American Journal of Epidemiology, used historical data from women who gave birth in Jerusalem in the early 1970s.

And Kanazawa, in a 2003 Sociological Quarterly paper, noted that even if wealthy men don't have more kids within marriage, they have...
