The percentage of single people between the ages of eighteen and thirty is far greater than that of the married ones, which is a natural expectation. Of the five hundred and thirty persons interviewed, two hundred and nineteen or forty-one and one-half percent were single; one hundred sixty-two or thirty and one-half percent were married, and had already brought their families here, while one hundred and thirty-nine or twenty-eight percent were married, but were here without their families. Ninety-eight of the families had children; thirty-nine of the families had no children here, and seventeen families either had some or all of the children in the South, while the remaining six placed their children under the care of relatives or institutions. The number of children per family of those who had their wives here, varied from one to ten. Forty families had one child each; twenty-three, two children each, fifteen had three children each, and twenty had four or more children each. Nineteen families had one or more children under twenty helping to support them, but only four had more than one child assisting in the support of the family. Among the one hundred and forty-nine persons whose families remained in the South, ninety-six had children and seventeen had none. Of the remainder a number stated that they had one or two of their children with them, while others gave no definite information. Sixty-three of those who had children at home had no more than two children each, while thirty-three had three or more children at home. These figures seem to indicate that the migration is largely that of small families. The Negro migration from the South into Pittsburgh, while it has been accentuated and accelerated by the present war, which created a greater need for labor, is not in reality an altogether new thing for Pittsburgh. There has been a steady influx of Negroes, though in small numbers, since the pre Civil War days. Pittsburgh and Allegheny were important stations of the Underground Railway, and many a Negro came to Pittsburgh from the near-by slave states, as to a city of refuge. The Negro population in Allegheny County grew steadily from 3431 in 1850 to 34,217 in 1910. The percentage of Negroes in the total population of the County has continually increased within the last four decades. (Two and two-tenths percent in 1880 and three and four-tenths in 1910). Negroes have always been attracted by the opportunities which this city with its abundance of work and good wages could offer them in improving their economic status. The recent unprecedented influx of Negroes had made the Negro population in Pittsburgh increase more than twice as fast within the last two years as during the entire ten years preceding. The percentage of Negroes in our total population has leaped very suddenly. This fact is sufficient to warrant our serious study and active efforts toward the social orientation and adjustment of the new element in our midst.
