The force of this query is exemplified when we turn from the political to the racial map of the globe. What a transformation! Instead of a world politically nine-tenths white, we see a world of which only four-tenths at the most can be considered predominantly white in blood, the rest of the world being inhabited mainly by the other primary races of mankind--yellows, browns, blacks, and reds. Speaking by continents, Europe, North America to the Rio Grande, the southern portion of South America, the Siberian part of Asia, and Australasia constitute the real white world; while the bulk of Asia, virtually the whole of Africa, and most of Central and South America form the world of color. The respective areas of these two racially contrasted worlds are 22,000,000 square miles for the whites and 31,000,000 square miles for the colored races. Furthermore it must be remembered that fully one-third of the white area (notably Australasia and Siberia) is very thinly inhabited and is thus held by a very slender racial tenure--the only tenure which counts in the long run. The statistical disproportion between the white and colored worlds becomes still more marked when we turn from surveys of area to tables of population. The total number of human beings alive to-day is about 1,700,000,000. Of these 550,000,000 are white, while 1,150,000,000 are colored. The colored races thus outnumber the whites more than two to one. Another fact of capital importance is that the great bulk of the white race is concentrated in the European continent. In 1914 the population of Europe was approximately 450,000,000. The late war has undoubtedly caused an absolute decrease of many millions of souls. Nevertheless, the basic fact remains that some four-fifths of the entire white race is concentrated on less than one-fifth of the white world's territorial area (Europe), while the remaining one-fifth of the race (some 110,000,000 souls), scattered to the ends of the earth, must protect four-fifths of the white territorial heritage against the pressure of colored races eleven times its numerical strength.
