It was more than just a map

Text descriptions known as "area descriptions" accompanied and explained the maps, often using racially loaded descriptions such as “infiltration of hazardous populations” or “invasion of hazardous groups” to describe neighborhoods. These documents then helped direct where home loans would be available.
