Another feature of the fluctuation is entitled to some consideration. In proportion to the population of those nations, the emigration from Norway and Sweden since 1870 has been very large, and such drafts as were made in the years 1882 or 1903 could not be expected to keep up. The periodicity of the ripening of a good "crop" of eligible emigrants for the great American West seems to have been since 1877 from five to eight years. In this connection it is a noteworthy fact that the population in each of the Scandinavian kingdoms, notwithstanding the great emigrations, has steadily tho slowly increased since 1850.[154] For the last decade of the nineteenth century, the figures for the increase were, Denmark, 16.6%, Norway, 10.6%, Sweden 7.3%, United States 20%.[155] In this statistical distribution, account must also be taken of the Scandinavians of the second generation, born in this country of foreign-born parents, since this element, racially speaking, is just as much an alien stock, with its inheritance of tendencies, temperament, and passions, as were the original immigrants. The census of 1910 enumerated among the foreign-born and the native-born of specified foreign parents:[156] Native white having Foreign-born both parents born Total white in specified country Danes 181,621 147,648 329,269 Norwegians 403,858 410,951 814,809 Swedes 665,183 546,788 1,211,971 --------- --------- --------- 1,250,662 1,105,387 2,356,049 To these must be added still another group, made up of those persons having a father born in Norway, Sweden, or Denmark, and a mother born in one of the other two countries, in other words, persons of pure Scandinavian descent. The number of such in 1910 was 72,152. It does not include, be it noted, those persons of equally pure Norse blood whose parents, one or both, were born in the United States. The minimum number of Scandinavians, then, in the United States in 1910, who must be taken into account in all calculations and estimates of power and influence exercised by that factor of the population, is 2,428,201. If it were desired to bring the estimate up to date, the immigration of 1910-1913 and an approximation of the increase of the native-born, would have to be included, and the grand total of persons of pure Northern stock would not be far from 2,700,000 at the present time (1913).
