There are two files associated with the content. The first is a listing of the variables and the number of strata (categories) associated with each variable. For example, there are two different cohort groupings of the "age" variable. One has 11 cohorts and the other 7. The collapsing of the cohorts is necessary to assure confidentiality (minimize the number of cells) when cross tabulating the variable with items like mode to work. This file can be viewed in HTML or as a PDF. (PDF format requires the free Adobe Acrobate reader available at www.adobe.com.)
The second file is the actual table content. It to can be viewed in either format.
If you have any questions about the table content please contact Elaine Murakami email@example.com or 206-220-4460, contact any one on the CTPP Working Group, or start a discussion on the CTPP-News listserv.
