If you’re interested in data visualizations of racial prejudice, at least in the Hennepin County (Minneapolis) area, the University of Minnesota’s Mapping Prejudice project may be of interest to you. For example, here is a map from 1952.
The blue areas are locations of properties which have racial covenants which prevented members of the Black community from buying or renting the property. They have data from 1910 to 1955.
A relative ran down some useful information earlier this year:
Those of us in South & Southwest Mpls and in the Southern ‘burbs may well have racial convenants on our home titles. While they can’t be enforced, they can be legally discharged from our properties. Please consider taking this action now. Is it symbolic at this stage of the game? Yes. Are symbols important? Yes. See more about how to check your title and what to do if it has a racial covenant.
