You can retrieve the preliminary 2014 Census tract income classes at
http://www.ffiec.gov/cra/default.htmKB's post has a description of calculating income class that I believe is confusing to a CRA neophyte. In her first paragraph she states that the calculation for borrower income class is done the same way as for tract income class and says,"Same denominator for both". But the denominator is not the same for both. The denominator is referenced to the MFI for the MSA or statewide non-MSA in which the loan is located. But in the case of the tract income class the number is changed infrequently whereas the denominator for the borrower income class is change annually.
The MFI used for tract income class used to be changed decennially (now the FFIEC will publish a new number every 5 years) or whenever a MSA or non-MSA definition has changed (OMB periodically will change the composition of MSA's).
The EMFI used for determining applicant income class is changed annually and published by the FFIEC with the annual census database usually released in June.
So the description of the denominator sounds the same because you are referencing the same geography level (MSA, MD or statewide non-MSA) but the actual denominators are quite different and subject to change at different times.
I am certain KB understands this distinction, but I don't think it is clear in her explanation.
