Fertility in the US is higher than that among those with bachelor's degrees, but at the doctoral level, nearly one in three women never get around to starting a family. There isn't much in the way of surprises (heh) across groups, but the GSS has tracked the same data since its inception back in the early seventies. So, for comparative purposes, the percentages of women of the same age grouping who participated in the survey from 1973 through the end of that decade and reported never having children are also included in the following table, which shows the percentage of women by educational cohort who reported having no children*:
|Less than HS||6.5%||7.0%|
|Up to associate's||12.8%||7.3%|
|Up to bachelor's||21.3%||10.0%|
|Up to master's||21.9%||14.9%|
|Up to doctorate||31.9%||32.1%|
No difference among those who climb to the top of the academic mountain today and those who did so a generation ago (although at that time they represented less than 1% of all women; today they comprise nearly 4% of the female population). A significant change has occured among those who attend college without going as far, however. The percentage of these women who are not having children has almost doubled in three decades, while among the least educated, the proportion who forego kids has been halved.
GSS variables used: YEAR(1973-1980)(2000-2008), SEX(2), AGE(36-62), EDUC(0-8)(9-11)(12)(13-14)(15-16)(17-18)(19-20), CHILDS
* No high school = 0-8 years of education; Some high school = 9-11 years; High school graduate = 12 years, Up to associate's = 13-14 years; Up to bachelor's = 15-16; Up to master's = 17-18 years; Up to doctorate = 19-20 years.
