Map displays the distribution of poverty across Los Angeles neighborhoods, with neighborhoods in deeper blue indicating higher poverty, overlaid with historic “redlining” zones. The HOLC created a grading system to reflect a neighborhood’s “mortgage security”. Neighborhoods receiving an “A” (colored green on the map above) were deemed minimal risks for banks and lenders. Those receiving a “D” (colored red on the map above) were neighborhoods that were considered hazardous and therefore “redlined.”
