Bryn Mawr College, between 1888 and 1900, graduated 376 girls, of whom 165, or 43.9%, had married up to January 1, 1913.
Studying the Vassar College graduates between 1867 and 1892, Robert J. Sprague found that 509 of the total of 959 had married, leaving 47% celibate. Adding the classes up to 1900, it was found that less than half of the total number of graduates of the institution had married.
Remembering what a selected group of young women go to college, the eugenist can hardly help suspecting that the women's colleges of the United States, as at present conducted, are from his point of view doing great harm to the race. This suspicion becomes a certainty, as one investigation after another shows the same results. Statistics compiled on marriages among college women (1901) showed that:
| 45% of college women marry before the age of 40. |
|---|
| 90% of all United States women marry before the age of 40. |
| 96% of Arkansas women marry before the age of 40. |
| 80% of Massachusetts women marry before the age of 40. |
In Massachusetts, it is further to be noted, 30% of all women have married at the age when college women are just graduating.
It has, moreover, been demonstrated that the women who belong to Phi Beta Kappa and other honor societies, and therefore represent a second selection from an already selected class, have a lower marriage rate than college women in general.
