Concerning Len's post, and additionally to mine -
IMHO, CRA measures where the loans are made in the designated AA. Fair Lending, which is usually examined at the same time
measures where the loans are NOT made in majority-minority tracts in the AA, or REMA (reasonably expected market area). You can take the whole county, but cannot reasonably serve all of it, and if you're missing loans from too many MM tracts, the bank can be criticized.
