FRED has 20 new series of summary statistics from “The Effects of the 1930s HOLC ‘Redlining’ Maps,” which is a recently updated working paper (August 2020) by Daniel Aaronson, Daniel Hartley, and Bhash Mazumder of the Chicago Fed.

These authors study the effects of the 1930s-era HOLC “redlining” maps on the long-run trajectories of neighborhoods. They calculate summary statistics based on U.S. Census estimates for each area matched to the geocoded HOLC neighborhoods. These neighborhoods are based on the geocoded renderings of the original Home Owners Loan Corporation (HOLC) maps for 149 cities.
