The Negro population has shown a greater increase than the white in each southern city taken separately for the entire period, 1860 to 1900, but together the movement of the white and Negro populations was similar except between 1860 and 1870. That fourteen of the southern cities show an excessive proportional increase of Negro population between 1860 and 1870 is probably due (1) to the very small proportionate Negro population in each of these cities in 1860, the Negroes being almost entirely in the rural districts, and (2) to the exceptional influences following the Civil War which uprooted the rural Negro population that was proportionately larger than the white. The truth of this is corroborated by the per cent of increase by decades for these southern cities taken together. Comparisons with the white population in Northern cities were not made because of the influence of foreign immigration of whites. The per cent of increase of the populations in Southern cities from 1860 to 1870 were white 16.7 per cent, Negro 90.7 per cent; from 1870 to 1880, white 20.3 per cent, Negro 25.5 per cent; from 1880 to 1890, white 35.7 per cent, Negro 38.7 per cent; from 1890 to 1900, white 20.8 per cent, Negro 20.6 per cent; from 1900 to 1910, white 27.7 per cent, Negro 20.6 per cent. That is, when the proportion between the urban and rural populations of blacks and whites becomes normal, and exceptional influences no longer bear upon the Negro, the two populations show about the same rate of increase in their migrations to these Southern cities. The percent of increase of the Negro population for eight Northern cities (counting all the boroughs of New York City as now constituted as one) was as follows: 1860-1870, 51 per cent; 1870-1880, 36.4 per cent; 1880-1890, 32.3 per cent; 1890-1900, 59.2 per cent. The larger liberty of Northern cities was coupled with the economic call of better wages. And this probably may account for the fact that Southern cities show an increase of whites of 7.7 per cent more than of Negroes between 1900-1910. The migration to both Southern and Northern cities is graphically illustrated in the accompanying diagram.
