1. TAZs were defined by the MPOs and states using basically a census
block to TAZ equivalency. The data crunching and table production was
done inside the Census Bureau.
2. This will all depend on what CTPP gets but it will be census
geography. I believe the ask from the Census Bureau is for block group
and tract level data, which likely has some relationship to the TDM
tazs, but the Census Bureau disclosure review board needs to complete
their review first before all the table details are know.

Hi,
I am new to the list and I want to post 2 questions:
1.Since CTPP data is based on ACS data and the lowest level of
geography of ACS data is block groups, how was CTPP data generated at
TAZ level?
2.Since TAZ level CTPP data will be discontinued, what will be the
best practice to get TAZ level demographic, socioeconomic and housing
characteristics data as input layers to travel demand model?
Thanks!
Best, **
