I have a question regarding 2000 CTPP data for counties that go "unclaimed"
by both MPO's and states regarding zone boundaries. Will data for those
counties continue to be in the statewide CTPP at the same level of geography
as in 1990 (by place over 2,500 for employment, by township and place over
2,500 for residence data)? Or would there be changes?
Elaine's response:
Our current plan is to have pretty much the same geographic levels as in 1990
CTPP, with the addition of something called "statewide TAZ".
So, that means,
For "state" level CTPP there will be
State
Metro Area
County
Place
State TAZ: We are still (!) struggling with this geographic unit, because of
the need to develop a way to provide equivalencies of urban TAZs (or census
tracts) to statewide TAZs in the metropolitan portions of the states, and the
possibility of some counties being composed of mostly urban TAZs and some
statewide TAZs in outlying areas.
For "urban" level CTPP there will be:
Region
MSA
Urbanized Area
Study Area
County
CBD
TAZ OR
Region-State-County-MCD-Place-Tract OR
Region-State-County-MCD-Place-Tract-Block Group
