Home Owners' Loan CorporationThe Home Owners' Loan Corporation was established in 1933 under the New Deal, it's purpose being to issue bonds and provide loans to new homeowners. As part of this process, it accessed the perceived value of neighborhoods, with each neighborhood colored coded to denote its "Desirability." In the maps they produced, areas deemed undesirable were marked red, creating the practice of "Redlining." Homeowners, banks, realtors, and government agencies would actively use this practice of redlining as a segregation tool.
