Detroit’s African American population has followed interesting migration patterns throughout the years. These are a series of maps that help demonstrate how people moved around the city as a result of changing racial attitudes, a growing black middle class, as well as shifting demographics from economic downturn. Paradise Valley can be easily seen in 1940 while it isn’t until later that we see other prominent black neighborhoods emerge to the West of Cass Corridor.
