Education leads to less baby making

In 1873 college-educated women were less likely to get married and bore fewer children than noncollege-educated women. Professors at the turn of the century, including Harvard’s eminent professor of education, Edward C. Clarke, attributed this link to the shrinking of women’s wombs. Social scientists declared that if a woman’s brain grew her uterus would shrink.

Today, childlessness is still most common among highly educated women. In 2008, 24% of women ages 40-44 with a bachelor's degree had not had a child. However, our explanations for this relationship have changed dramatically. Researchers have found that improved career opportunities and contraceptive methods have created more alternatives for women than in the past.
