“Like many inner cities, the Whites (or White ethnics) were displaced by Blacks in those neighborhoods in the 1950s...”
They weren’t displaced, they fled when the first black families started moving in. They knew what was going to happen. The decay of the neighborhood, the drugs, the crime, destruction of the schools, the drop of property values, the race to sell. Get out while you can.
my aunt/uncle owned many buildings in Cleveland in the late 40’s and early 50’s.
a black gentleman told my uncle to sell, get out because “ the n!gg@*s are coming” (up from the south) so that sounds about right.
