(4) Education has been alleged as a cause of decreasing birth rate in the native white American stock. This, however, is true only in a very qualified sense. While it is a fact, as collected statistics have shown, that if Harvard and other universities depended on children of their alumni for students their attendance would actually decrease in numbers, it is not true that college graduates have had a lower birth rate than the economic and social classes to which they belong. So far as statistics have been collected, indeed, they seem to indicate that the wealthy uneducated are producing fewer children than the educated classes who associate with them. The influence decreasing the birth rate among the educated is, therefore, not education itself, but the high standards of living and the luxury of the classes with whom they associate. On the other hand, the higher education of women seems to be, down to the present time, operating as a distinct influence to lessen the birth rate among the educated classes for the reason that apparently a majority of educated women do not marry. The higher education has not yet gone far enough, however, to give us any definite facts with which to judge what the ultimate effect of woman's higher education will be. If the higher education of woman is going to lead to a large per cent of the best and most intellectual women in society leading lives of celibacy, then, of course, ultimately the higher education of woman will be disastrous to the race. But probably the relative infrequency of marriage among women who are college graduates is a transitory phenomenon due to the fact that neither women nor men are as yet adjusted to the higher education of women.
