i like bob usually have an answer or think i do<grin>.
it is my understanding that in situations like this, bob would get data for
the whole county if he wants, with his geography for the portion he defined
and the st cloud geography for the portion that they defined. this i
believe to be true. in effect, if an MPO wants CTPP flow data for an area
outside the area where they defined the TAZs, they will get the lowest level
geography that was defined for that area--be it tracts, block groups or some
taz configuration. things that i am not clear on is if for some reason both
bob and st cloud used a TAZ numbering system that for some reason was the
same within their respective portions of the shared county how that would
get sorted out--but i think i am over analyzing for now and getting into the
to get a feel for what that geography may be, i would think that bob, or
anyone for that matter, could look at the TAZs in tiger to see what is
there. this should be the telling story.
i will sit back and wait for phil salopek or one of our other census bureau
friends to confirm and/or clarify what i think i understand about this part
of the effort.
another question that this raises for me, is when will the CTPP developers
be asking MPOs for the areas that they want CTPP flow data for? i understand
that there is request out from the census bureau now asking MPOs to verify
what their MPO region is. i am reading that to be the area for which they
defined TAZs. (this needs to be clarified as well).
i think i better stop here and wait, before i wake up mr. purvis on the west
coast and he adds another mountain of questions that i know he has ginned

Since I usually have an answer for everything (right or wrong), it left
me feeling incomplete. So I'm posting it here in the hopes that someone
may help me out.
We were wondering what we will get from the Census Bureau in the form
of the CTPP as it relates to the TAZ system in our region. We defined
TAZs for not only our 7-county jurisdictional area but for an additional
13 contiguous counties in the hopes that we can receive a bit more
information on commutes in the whole Minneapolis-St. Paul region.
Adjacent to us is the St. Cloud, MN MSA, a metro area of over 200,000.
They also defined a TAZ system that included a portion of Sherburne
County. Since the Census Bureau only allows one TAZ definition, we
created TAZs for only the remaining portion of Sherburne Co. Upon
submitting our TAZ definition using the TAZUP process to the Census
Bureau, that part of Sherburne Co. NOT defined by us was given a "ZZZZZZ
Now. When the CTPP is released, will we receive ONLY that area we
defined? OR... will we receive our defined area PLUS that segment
defined by St. Cloud? If we receive the whole package, can we also
obtain both metro areas as an interconnected TAZ system?
Anyone care to comment? There must be someone out there full of enough
bull like me to say a few words!!
