the census of 1910 of 68,070,294 native whites, 10,366,735 or 15.2 per cent were living in some other division than that in which they were born. Of 9,746,043 native negroes reported by the census of 1930, 963,153 or 9.9 per cent were living outside the division of birth.[12] Previous to the present migration, the south Atlantic and the east south central divisions were the only ones which had suffered a direct loss in population through the migration of negroes.[13] The census of 1910 brought out the fact that there had been considerable migration from the North to the South, as well as from the South to the North, and from the East to the West. The number of persons born in the North and living in the South (1,449,229) was not very different from the number born in the South and living in the North (1,527,107). The North, however, has contributed more than five times as many to the population of the West as the South has. The number of negroes born in the South and living in the North in 1910 was 415,533, or a little over two-thirds of the total number living in the North. Of the 9,109,153 negroes born in the South, 440,534, or 4.8 per cent, were, in 1910, living outside the South.[14] The migration southward it will be noted, has been in recent years largely into the west south central division, while the migration northward has been more evenly distributed by divisions, except that a comparatively small number from the South have gone into the New England States.[15] The greater mobility of whites than of negroes is shown by the fact that in 1910, 15 per cent of the whites and 10 per cent of the negroes lived outside of the States in which they were born. This greater mobility of the whites as compared with the negroes was due in a large measure to the lack of opportunities for large numbers of negroes to find employment in the sections outside the South. The World War changed these conditions and gave to the negroes of the United States the same opportunities for occupations in practically every section of the country, which had heretofore been enjoyed only by the whites. In 1900, 27,000 negroes born in the North lived in the South. In 1910, 41,000 negroes born in the North lived in the South. This indicated that there was beginning to be a considerable movement of negroes from the North to the South because of the greater opportunities in the South to find employment in teaching, medicine and business. The migration conditions brought about by the war have probably changed this to some extent. Previous to the World War, the States having the greatest gain from negro migration were Arkansas, 105,500, Pennsylvania, 85,000, Oklahoma, 85,000, Florida, 84,000, New York, 58,450 and Illinois, 57,500.
