A realization of the need for accurate information concerning the Negro migration, and the belief that in an intelligent treatment of the problem lay the welfare of the entire community as well as that of the local Negro group, prompted the attempt at a scientific study of the situation. The primary purpose of the study was to learn the facts, but there was also a hope that the data obtained might lead to the amelioration of certain existing evils and the prevention of threatening ones. In order to ascertain as many of the facts as possible concerning housing conditions, rooming and boarding houses, three or four family tenement houses, single family residences, camps, churches and other lodging places were investigated. A comparative study of health and crime among Negroes of Allegheny County before and after the period of the Northern migration was also attempted. [Illustration: Storerooms in the Hill District Converted into Family Residences and Rooming Houses.] A questionnaire concerning kinds of labor in which Negro migrants engaged, and wages paid them both in Pittsburgh and in their native South was prepared; and answers to it from over five hundred individuals were obtained during the months of July and August, 1917. Information relating to housing, rents, health and social conditions was elicited in a similar manner. An effort was made to visit and study every Negro quarter in Pittsburgh. Data was secured from the Negro sections in the Hill District and upper Wylie and Bedford Avenues; the Lawrenceville district, about Penn Avenue, between Thirty-fourth and Twenty-eighth Streets; the Northside Negro quarter around Beaver Avenue and Fulton Street; the East Liberty section in the vicinity of Mignonette and Shakespeare Streets, and the new downtown Negro section on Second Avenue, Ross and Water Streets. The information thus secured is discussed in the following pages. _TABLE NUMBER I_ _Time of Residence in Pittsburgh of 505 Negro Migrants Questioned_ SINGLE MARRIED 1 MONTH █████████████████ 86 ███████████ 58 3 MONTHS ██████████ 51 ██████████████ 70 6 MONTHS █████ 28 ███████████████ 74 12 MONTHS ████ 21 ████████████████ 80 OVER 12 ███ 13 █████ 24 TOTAL PERCENT 1 MONTH █████████████████████████████ 144 29 3 MONTHS ████████████████████████ 121 24 6 MONTHS ████████████████████ 102 20 12 MONTHS ████████████████████ 101 20 OVER 12 ███████ 37 7
