I was able to see an analysis of large data sets for a big metro are and zoom in on neighborhoods I am familiar with. One can see that in some neighborhoods traditionally majority-minority, that nearly all new mortgages are going to white households.
An enterprising journalist could use this data to start up another piece on bank-enabled gentrification in a particular part of the country starting with this national data set, add in historic home values, etc.
