Religious differentials in reproduction: the effects of sectarian education.

College-educated Catholic women in the 1976 National Survey of Family Growth had higher actual and expected fertility than did college-educated Protestants. Moreover, Catholic colleges or universities had a pronatalist effect on alumnae. Thus, a significant part of the higher Catholic than Protestant cumulative fertility among college-educated women arose from the greater propensity of such Catholics to attend sectarian schools and colleges. The implications are explored.
