Thanks, I also plan on using the 1990, 2000, and 2006-2010 to show the change in the
percent and number of people and per household that commute to work in Manhattan from
different MCD’s in NJ to see if there are any patterns. This is critical because since
about 1996 we have spent about $3.5 Billion on a new LRT line, two new commuter rail
connections to NY and a major commuter rail transfer station along with expanded ferry
service. By going back to 1990 we can see how these investments have changed commuting
patterns over 20 years. I have the data for the 2000 and 2006-10 so this is the missing
piece. Tom Marchwinski

We will have to wait for JJ Zang at Cambridge Systematics to figure out the problem with
the FTP site.
We know that using CS to archive the data is not the right approach to data archiving. We
are working on moving the 1980 UTPP files to ICPSR.
We have not discussed where to archive the 1990 CTPP Part 7 file.

Sorry, but the username/password for the 1990 data isn't working.

Hi Everyone,
The 1990 CTPP Part 7 data, which include all states, are now available for download at:
ftp://ftp.camsys.com/clientsupport/CTPPdata/1990%20CTPP%20Part7/
The 1980 UPTT data are flat files and only available for certain MPOs. The data, along
with a summary file for data sources and formats are also available at:
ftp://ftp.camsys.com/clientsupport/CTPPdata/1980UTPP/
Please use the user name and password for both sites:

Are there any plans to post the 1990 and 1980 data online so that interested parties can
download the same?

1990 CTPP Part 7 at tract level! I did not remember that. I had Brian Gardner look
for the CDs in my cubicle at USDOT Navy Yard. JJ Zang will pick them up in the later part
of next week (after the TRB Planning applications conference) and make a copy for Chuck.
There are 4 CDs and until we look at them, we will not know if all the states are
included.

p.s. Bob Paddock of Met Council found the 1980 UTPP file layouts and will be sending them
to me! So, now we can write SAS code to read in the flat ASCII files.

Chuck- I wonder if the 1990 CTPP part 7 will help. It had tracts at the workplace but I
am not sure if it covered the the whole state. And then finding it is another issue. Here
is what i found to atleast shed some light on part 7, see page 188.
http://onlinepubs.trb.org/onlinepubs/conf/1995/cp4/cp4.pdf. I could not find any of my
1990 transview versions of the data. I know I have a complete set minus one state
somewhere. If you can find one of the CDs even though you can not extract the data
without the extraction software look on it to see if there are any PDF files with
documentation stashed on it. I seem to recall that there is.
Sorry I could not be any more help right now.

Hi all!
Ed or Elaine will probably be able to answer my question, but all might (or might not) be
interested.
I’m interested in developing a historical database showing tract-level data on total
population, land area, and workers-at-workplace, for 1990, 2000 and 2006/10. I want this
at a statewide (California) level, not just for the metropolitan areas. This is part of an
ongoing research project on describing changes in rural/suburban/urban patterns in
California (perhaps elsewhere, as well).
The 2006/10 CTPP includes a tract-level summary level, so I have been able to obtain a
statewide, census tract level file of workers-at-work from Part 2 tables.
Similarly, about 11 years ago I extracted a block group-level file of population (Census
SF3) and workers-at-work (CTPP 2000, Part 2), which is easily aggregated to census tract
level.
The 1990 CTPP is the first “nationwide” CTPP product. The “statewide” element includes
place-to-place, county-to-county for ALL counties in the USA, including rural
(non-metropolitan) counties. On the other hand, the “urban” elements of the CTPP is
restricted to metropolitan counties, and the finest level geographies are either TAZ,
block group or census tract. Whether or not the TAZes aggregate to census tracts is
unknown.
So, am I correct to assume that the Part 2 (workplace tables) from the 1990 CTPP do NOT
include tract-of-work data for non-metropolitan counties? That’s my central question.
A secondary question is: is there a scanned/PDF version of the 1990
CTPP documentation? (I searched my old website, and I don’t think I
have it in electronic format….)
I know that the 1980 UTPP was only completed for metropolitan areas, on a
cost-reimbursable basis. Some MPOs in California didn’t participate in the 1980 program.
That’s all for now!
