In Detroit, a large proportion of ghettofied housing was originally built
for middle and upper income occupants. As the process of ghettofication
occurred this housing was increasingly
occupied by lower income people. The ensuing disinvestment caused a spiral of decline in this former neighborhood of gentry as mansions were
subdivided into several apartments with impoverished tenants. As ghettofication
increased the houses were
not maintained and blight
engulfed the neighborhood.
