the nineteenth century there were between four and five children to each marriage, while by the end of the century the number of children had fallen to between four and but little over one. > Engelmann finds that there is but a very trifling difference in this respect between the upper and the lower social classes; the average for the labouring classes at St. Louis he finds to be about two, and for the higher classes
It is among the foreign-born population, and among those of foreign parents, that the larger families are found; thus Kuczynski, by analysing the census, finds that in Massachusetts the average number of children to each married woman among the American-born of all social classes is 2.7, while among the foreign-born of all social classes it is 4.5.
Moreover, sterility is much more frequent among American women than among foreign women in America. Among various groups in Boston, St. Louis, and elsewhere it varies between 20 and 23 per cent, and in some smaller groups is even considerably higher, while among the foreign-born it is only 13 per cent.
The net result is that the general natality of the United States at the present day is about equal to that of France, but that, when we analyse the facts, the fertility of the old native-born American population of mainly Anglo-Saxon origin is found to be lower than that of France. This element, therefore, is rapidly dwindling away in the United States. The general level of the birth-rate is maintained by the foreign immigrants, who in many States (as in New York, Massachusetts, Michigan, and Minnesota) constitute the majority of the population, and altogether number considerably over ten millions. Among these immigrants the Anglo-Saxon element is now very small. Indeed, the whole North European contingent among the American immigrants, which was formerly nearly 90 per cent of the whole, has since 1890
