(3) Besides economic conditions and individual selfishness we must unfortunately add another cause of decreasing birth rate in our population which has been definitely ascertained, and that is vice. Vice cuts the birth rate chiefly through the diseases which accompany it. About 20 per cent of American marriages are childless, and medical authorities state that in one half of these childless marriages the barrenness is due to venereal diseases. According to Dr. Prince A. Morrow, in his Social Diseases and Marriage, 75 per cent of the young men in the United States become impure before marriage. This serves to disseminate venereal diseases among the general population, especially among innocent women and children. The consequence is, on the one hand, a considerable number of sterile marriages and on the other hand a high infant mortality. It need not be assumed, as we have already said, that vice is more prevalent to-day than in previous generations, but on account of the conditions of our social life diseases which accompany vice are now more widely disseminated than they have been at any time in our previous history; therefore, even the physical results of vice are different to-day than they were a generation or more ago.
(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.
(5) Some phases of the "woman's movement" have without doubt tended to lessen the birth rate in certain sections of American society. Some of the leaders of the woman's movement have advocated, for example, that women should choose a single life, while others have advocated that families should not have more than two children. Mrs. Ida Husted Harper, indeed, has gone so far as to claim that if families would have but two children this would be a cure-all for many social troubles. Indeed, this ideal of two children in the family has been so widely disseminated in this country that it is often spoken of as the "American Idea." Of course, such teachings could not be without some effect. Without attempting to reply to the advocates of this theory of but two children to a family, it will be sufficient to remark that for a population simply to remain stationary three children at least must be born to each family on the average; otherwise, if only two children are born, as one of the children is apt to die or fail to marry, the population will actually decrease in numbers. Under the best modern conditions one out of three children now born either fails to live to maturity or fails to reproduce. There must be, therefore, more than three children born to the average family for a population to grow. From the sociological point of view the ideal family would seem to be one in which from three to six children are born.
(6) Finally, not all of the childless and small families in the native American stock are due by any means to voluntary causes, or even involuntary causes of the kind that we have mentioned. There are also certain other obscure physiological causes at work producing sterility in American women. The sterility of American women is greater than that of any other civilized population, even apart from the causes which have just been mentioned. Some say this is due to physical deterioration in the native white American stock, and there are other things which seem to point in that direction. It may be, however, that this deterioration is in no sense racial, but only individual, affecting certain individuals who lead a relatively unnatural life. Our American civilization puts a great strain upon certain elements of our population, and this strain in many cases falls even more upon the women than upon the men. The social life of the American people, in other words, is oftentimes such as to produce exhaustion and physical degeneracy, and this shows itself in the women of a population first of all in sterility. It is evident that the remedy for this cause is a more natural and more simple life on the part of all, if it is possible to bring this about.
Thus, the causes which influence birth rate are evidently very complex. In the main they are doubtless economic causes among all peoples, but there is no reason to believe that these economic causes act alone in determining birth rate, nor is there any reason to believe that the other psychological and biological causes may be in any way derived from the economic. So far as we can see, then, industrial conditions are mainly responsible for the lessened birth rate in the native white American stock. But mingled with these industrial conditions, operating as causes, are certain psychological (or moral) and biological factors that have to be considered as in the main independent. It is furthermore evident that the causes which lead to the decline and extinction of any population, whether civilized or uncivilized, are complex. All efforts to explain the extinction of peoples of antiquity, or modern nature peoples, such as the North American Indians and the Polynesians, through any single set of causes, must be looked at as unscientific. It can readily be shown that in all these cases the causes of the decline of the birth rate and the ultimate extinction of the stock are numerous and are not reducible to any single set of causes.
Causes which Influence the Death Rate. Before we can fully understand the causes of the growth of a population, that is, of the surplus of births over deaths, we must understand something also about the things which influence the death rate as well as the things which influence the birth rate, because, let it be borne in mind, the growth of a given population (excluding immigration always) is due to the combined working of these two factors.
