Hi,
If you are a vendor, or consultant, or academic, who uses the CTPP data please email me at

New subject: 1990 and 2000 CTPP contents
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!

Chuck--I will try to look around to verify but her is what I recall. I
believe that you are right that we did not have workplace wall-to-wall
coverage at the track level for 1990. As to documentation I seem to
recall that the CDs had a lot of stuff on them. Let me did around and
see where I put mine. As for the 1990 data it is still on the BTS
website. I only know how to find by goig to a link I bookmarked a long
time ago.
http://www.transtats.bts.gov/Tables.asp?DB_ID=620&DB_Name=Census%20Tran…
I will let you know if and what I turn up on documentation.

Hi Everyone -- (Ed started working on his response before me!)
ALL of the 1990 CTPP are available at BTS. The easiest way is to use a search engine and
say "BTS 1990 CTPP".
JJ Zang our CTPP tech support will download the 1990 file documentation and send it
directly to Chuck Purvis.
Re: 1990 CTPP outside of metropolitan areas. The Census Bureau was not confident about
geocoding workplace locations outside of metropolitan areas at that point in time.
Re: 1980 CTPP When Nanda Srinivasan worked for the CTPP program, he collected a FEW
files from States and MPOs. Most of these are flat ASCII files. We are looking for file
layout information. If you have a copy of the file layout (that is, which columns are
which variables), please send to me. This was back in the days where, the part 1 record
was in 8 "segments". We can probably figure it out, by dumping records to
print, but that sounds painful. My goal is to send these files to ICPSR at Univ of
Michigan but they want files in SAS format.

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.

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!

Thank you very much for the data. I’m not sure what I will do with it. But, it is great
to have.
I do have a couple of comments/questions….
· Am I mis-understanding the 1980 dataset? Shouldn’t the folder/sub-directory be
named to reference San Jose rather than the San Joaquin Valley?
· Is there no data for the ‘West Region’?

look on it to see if there are any PDF files with documentation stashed on

New subject: 1990 and 2000 CTPP contents
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

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:
username: CTPPreader

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!

Chuck,
I have a CD of the special tabulation "STP154 -- CENSUS TRACT OF WORK BY CENSUS TRACT
OF RESIDENCE" if that would help. See the attached doc.
