Historic Redlining Indicator (HRI) data by the Mapping Inequality project include data from the federal Home Owners’ Loan Corporation’s (HOLC) residential security grades, multiplied by a weighting factor based on area within census tracts. A higher score means greater redlining with the census tract. The 1930s HOLC maps were calculated for 2000, 2010 and 2020 census tracts for 142 cities across the U.S. The data contain continuous HRIs and categorical variables. More information is available at the Mapping Inequality project website.
