In using the CTPP Part 2 tables I have found some instances where there is
no row/entry for a particular TAZ. For example, I was looking for data on
occupation by means of transportation to work and there is no entry for one
of the TAZs in the town I am looking at. Has anybody else run into similar
situations? My guess is that this is how the tables indicate "no data" or
zero values, but I would appreciate anybody being able to confirm this (or,
if my guess is wrong, let me know why rows for particular TAZs may be
missing from tables).
Thanks.

Brian-Your guess is exactly correct. In most cases if a zone has no data it
will not show up in the table listing. There could be some exceptions to
this. The big exception would be if there were data for the missing zone but
for a different universe. I can't think of any obvious examples but I suspect
it could happen more with Part 1 data where there are more universes.
