1. when?--we are hoping that the software and the TIGER/Line 98 CDs will ship
at the end of January. MPOs and State DOTs will have six months to return the
files to the Census Bureau.
2. Minimum threshholds? We are still waiting to hear from the Census Bureau
Disclosure Review Board. When I went to APDU, there was some discussion that
Block Group recommendation was to have threshhold of about 600 persons.
However, Phil Salopek of Census Bureau Journey to Work thinks that CTPP may
not have to meet the same requirements.
