If I understand it correctly, the TAZ system being created by MPOs for submittal to the Census Bureau will be used to obtain the ‘CTPP-like’ product being paid for through AASHTO.  As far as the ACS tabulations are concerned, we will still only have existing Census geography, e.g. county, MCD, tract.  TAZs will NOT be part of that geography.

My question is, “Am I correct in this assumption?”
