thanks phil for the update. in the april issue of the "Satus Report"
that was just posted at
is an article
updating the current geocoding progress. it seems to be going quite
well and will be of much higher quality than in past CTPPs.
there is also a good article on the use of pums as well as some of the
other work that is underway with OMB regarding the justification of the
long form/acs transportation related questions. again the newsletter
"status report" is posted at
Last December, we sent a message to this listserve to see how many MPOs
would be willing and/or able to assist the Census Bureau in resolving the
most difficult to geocode place of work responses from Census 2000. We
received responses from over a hundred agencies, the vast majority
indicating that they would participate in such a program. Some of you may
remember that a similar activity was planned for the 1990 Census, but the
Bureau never implemented it and no MPOs were given an opportunity to
Based on the number of favorable responses to our December inquiry, I went
forward within the Bureau to try to get approval for this activity for
Census 2000. I spoke with our Policy Office and with our Legal department.
Some questions about confidentiality and Title 13 requirements were raised,
and I was directed to present my case to the Bureau's Disclosure Review
Board (DRB). I submitted a request to the DRB for approval to implement
the program, emphasizing that the information provided to the MPOs would
not be individual responses. Rather, we would group responses from several
people that seemed to represent the same employer or workplace location,
building synthetic responses or what we call "clusters." In effect, the
MPOs would be receiving address information culled from a number of census
In mid-March I received a decision from the Disclosure Review Board. They
turned down my request to implement a program that would allow MPOs to
assist in Census 2000 geocoding. It was felt that the addresses provided
to the MPOs would become a microdata file of working places, and the Census
Bureau does not release such files at the street address level or by
employer name. Therefore, we will not be contacting any of you for
assistance with our geocoding operation.
I would like to thank those of you who responded to our December inquiry; I
appreciate everyone's willingness to devote valuable time and resources to
projects such as this, the TAZ-UP program, and the Workplace Update
program. I look forward to continuing to work with you on our next big
joint project, the Census Transportation Planning Package 2000.
