The National Community Reinvestment Coalition (NCRC) has put together an incredible interactive map and dataset of all Home Mortgage Disclosure Act (HMDA) data since 1981. HMDA was created as a stop gap to use data to identify if redlining was still occurring. In recent history, HMDA was a data source that demonstrated “reverse redlining.”

“this interactive map shows the geographic spread of originations at the metro-, county-, and Census tract-level throughout the United States in circles of various sizes. High Minority (50-80%) and Very High Minority (> 80%) are shown in light purple and dark purple, respectively.”
