Thanks Chuck, I added the link to the TRB Census data subcommittee web links page
(http://www.TRBcensus.com/). On another note, I just created a page called
"adjustment" to collect information on the recent under/over count adjustments.
Its direct
URL is http://www.TRBcensus.com/adjustment.html. When using information from the sites
listed, make sure to know if you are looking at things from the first adjustment done as
part as A.C.E or A.C.E II. Finally, for those working with the County
flows who want to see a paper from the Chicago area point your browser to
http://www.berwyned.com/papers/co2cochgo.pdf

The 1970, 1980 and 1990 data on county-to-county total commuter flows is available on the
Department of Commerce, Bureau of Economic Analysis web site at:
http://www.bea.doc.gov/bea/regional/reis/jtw/
Anything finer grained that county, or county-to-county by means of transportation to
work, would have to be extracted from your old 1970 UTP, 1980 UTPP and 1990 CTPP data
files.
