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?"

Hi Bob - You are correct.
For the Census Bureau's STANDARD ACS tabulations, only Census geography
is used, like tracts and block groups. (note that the Census Bureau is
NOT planning to release block group tabulations in American FactFinder.
When a table is created for Block Group geography, it will only be
available in summary file format in a data download area.
For the CTPP which is a CUSTOM tabulation using ACS microdata records,
TAZs will be a tabulation geography.

Generally you are correct but let me add a little more detail. There are
two types of ACS products coming out. Standard Census Ones and ones paid
for by the CTPP program.
For Census Bureau standard products the first 5-year ACS product will be
released in December and will have Block Groups, Tracts, MCDs (I think for
the 12 new england states), Places, Counties, Urban Areas, etc. Here is
the log list of census geography.
http://www.census.gov/acs/www/data_documentation/geography/
Sometime soon the CTPP program will be releasing a product using 3-year
ACS data. It will contain data for places over 20K people (including
qualifying counties, PUMAs, MCDs in the 12 new england states).
Sometime in the late summer or fall of 2012 the CTPP program will be
putting out a 5-year ACS product which will contain NEW TAZs and TADS.
The TADs will be a geography defined by the states and MPOs that
approximates 20K people.

Thank you, Ed.
The City of Minneapolis is expecting to be able to obtain future ACS datasets at the
TAZ-level of detail. We are to meet next week to discuss the new 2010-TAZ system being
developed for the region. They are wanting it to coincide with tract boundaries; the MPO
needs them to align with minor arterials for modeling purposes, and the question of TAZs
and how they gel with ACS tabulations is to be discussed.
Thanks for the speedy reply.
BOB

The TAZ delineation software FOR CTPP will include the 2010 Census tract
geography.
