Title	Digitized polygons of HOLC maps showing graded neighborhoods
Abstract	This dataset shows neighborhood real-estate investment security Grades determined by the Home Owners' Loan Corporation. In 1935, the Home Owners' Loan Corporation created maps for 239 cities to indicate the level of security for real-estate investments. Areas were graded "Type A", most desirable for mortgage lending, to "Type D", least desirable, based on data which included housing quality, sale and rent history, and racial and ethnic identity of the area. These grades contributed to redlining, making it difficult for people in certain areas to access financing and become homeowners. These practices led to inequalities that can be seen today.
