To help explain the area rating, these HOLC documents often include discussion of the transportation facilities and housing conditions in a neighborhood, as well as the economic class, nationality, and race of residents.
In Chicago, IL, the area description for the Little Italy neighborhood illustrated the geographic shifts of populations: “Population is predominantly Italian; there is a marked infiltration of negro from the area on the south who, in turn, are driving the Italians into the section on the north. Most properties are little better than minimum shelter and rents here are about as low as it is possible to imagine....As a residential area, it has no future, but a slum clearance project could well be located in this district. Neighborhood is graded fourth class because of the presence of so many adverse influences and the absence of anything favorable.”
In Brooklyn, NY, the Brownsville area description lists detrimental influences as “Congestion. Poor upkeep. Lack of pride. Pushcart vendors and curb markets. Elevated structures Fulton Street—Atlantic Ave. Railroad and industry to the East and South. Mixture of races. Communistic type of people, who agitated ‘rent strikes’ some time ago.”
