Caliper has processed the most recent estimates of the CTPP data for the most commonly utilized tables from the latest American Community Survey (ACS) and is making the three part series available to all TransCAD users with current support agreements. For Parts 1 and 2 the data is in the TransCAD Fixed Format Binary table format, while the Part 3 data is in TransCAD matrix format. The data extents are nationwide, including the TAZ to TAZ journey-to-work flows, a matrix of 217,282 rows and columns with 58 sub-matrices.
