[CTPP] Clarification of TAZ-TAZ data for CTPP2000

First, let me thank Patty for her insightful comments. I wish I could have attended the conference on privacy and confidentiality that occured just before TRB! The CTPP Working Group has been working very diligently with the Disclosure Review Board on the final tables to be included in the CTPP 2000. The DRB approved the residence-only and workplace-only tables. However, the home-to-work tabulations required a lot of discussion. The TAZ-to-TAZ tables are MORE THAN A COUNT OF WORKERS. As it stands now, we have a list of 14 tables, of which 5 are subject to a threshold of 3 unweighted records, and 9 which will be reported without a threshold. Please see the January 2002 CTPP Status Report at www.trbcensus.com for a near final list. Table 3-2 on the list has been replaced with Means of Transportation (7 categories) by Vehicles Available (3 categories).
