Of the more than four hundred men who stated their reasons for coming North, three hundred and twenty-five said that the higher wages and economic opportunities here had attracted them. Two hundred and eighty-eight of these also included better treatment as one of the factors in their migration. As one of them expressed it, “If I were half as well treated home as here, I would rather stay there, as I had my family there and had a better home and better health.” Eighty-five had no special reason for their coming, and were “jes travelin’ to see the country”, or the like. Twenty-five were either tired of their work or wanted to change it. This was the case particularly with the miners from West Virginia and Alabama. Twenty-seven had either lost their jobs, were out of work, or had various other reasons for coming. These figures seem to indicate that the prime causes of the migration are rather fundamental, and not merely temporary. The Negro migration is similar to the previous European immigration because, while dominantly economic, it is also due to social and political maladjustments; but it is more largely a family migration. For the number of Negroes who brought women and children with them is greater in proportion to the total than was the case with the foreigners. The European usually came alone and sent for his family after a considerable lapse of time. The Negro either brings his family with him or sends for it within the first three or four months following his arrival. The complication of our housing problem is obvious under these circumstances, for Pittsburgh until the present time has attempted to meet the housing requirements of only single men workers of the new labor group. The short-sightedness of our failure to provide decent homes in the city, in order to retain the labor which is so essential for the expansion of Pittsburgh and the growth of its industries, is again exposed by the figures in our study. Of the three hundred and thirty single men, or men without families here, answering the question as to whether they will remain here, return South or move elsewhere, only ninety-two or twenty-eight percent said they would remain here. A hundred and thirty-seven or forty-two percent were going back or somewhere else, while one hundred and one or thirty percent were still undecided. As for the reasons why these men would not remain in the city, seventy-nine or fifty-seven percent were leaving because they could not get a better room because the rents paid by them were too excessive for the wages received; thirty-seven or twenty-seven percent, gave family connections as their reason, and the remaining sixteen percent either had no reasons or were leaving because of ill health, bad climate or other unfavorable conditions. The difficulty of securing an adequate labor supply for Pittsburgh is thus, in part, explained by the very nature of the economic problems involved.
