Redlining maps directly caused segregation, abandonment, and concentrated poverty.

Evidence

These security maps, a central technology of residential planning and management across US cities from the late 1930s on, became the basis across many years to follow for denying mortgage loans by government and private banks especially to black home seekers and in black neighborhoods. They thus fueled racial residential segregation, urban abandonment, and ultimately capital flight, thus hyper-concentrating racial poverty, slum conditions, and urban blight. Today’s gated communities are essentially privatized modalities of redlining, segregating communities informally extended. — David Theo Goldberg, The Threat of Race, 374
