82 THE SHADOW OF THE WORLD’S FUTURE to migration, For the transfer of people with unsuit- able ideals into the midst of others of higher status would be a most unsatisfactory migration. We are involved thus in considering aspects of the question which at first sight might appear quite irrelevant. To consider for a moment the simple matter of the degree of luxury to which a people has become accustomed, the complication of its mode of living, and the consequential effects of these, it is easy to see how these things operate. Increase of population depends mainly upon the frequency of marriage, upon its taking place early, upon its fertility, and upon the age at which that fertility eventuates. A thrifty self-denying people reaches the economic possibility of marriage earlier, while luxuriousness, inordinate love of wealth, marriage with persons of disparate age,! etc., all tend to reduce both the frequency of marriage and its fertility when it actually occurs. The economic load borne by a fertile married people is greater than that which is borne by those of less fertility. Thus personal qualities are factors of very high importance, a fact well illustrated by history. The growth of the population of the United States of America reveals this in a very remarkable way. As was mentioned earlier, from 1790 to 1860 the rate of increase was sensibly uniform, and was no less than a little over 3 per cent. per annum. And since 3 per cent. per annum means the doubling of a population in 23°45 years, the attainment of such a rate involves the exercise of sterling physical and moral qualities. These in their turn have an influence on migration: see the table hereinbefore, Chapter V. (page 58). Although physical and other complexities in the distribution of the human race over the earth’s surface + It has been shown that fecundity depends upon the ages of both husband and wife.
