RE: [CTPP] PUMS Boundary Criteria

Does this approach make sense in bi-state metro areas like Kansas City?

We appreciate that Ed Christopher made these documents available to readers of the ctpp-news maillist so that the MPOs are aware of this program. Ed correctly stated that the Census Bureau is only inviting the SDCs to participate, and that interested MPOs should contact their SDC and inquire if their input is desired. We would like to emphasize that the Census Bureau has no plans to work directly with any MPO. All PUMA submissions must come from the SDCs. If a SDC declines to participate, Census Bureau staff will delineate the PUMAs for that state, and do so without soliciting or utilizing any input from sources other than the SDC. ed christopher <berwyned(a)mcs.com To: ctpp-news maillist <ctpp-news(a)chrispy.net> Sent by: Subject: [CTPP] PUMS Boundary Criteria owner-ctpp-news@c hrispy.net 05/03/2001 07:48 PM Last week the Census Bureau (CB) sent a letter to the State Data Centers(SDCs) asking them to participate in the delineation of the Public Use Microdata Sample (PUMS)zones. A copy of that letter and the criteria used in defining the zones (know as PUMAs) can be found on the TRB census data subcommittee's web page at http://www.mcs.com/~berwyned/census/ The direct link for the information is http://www.mcs.com/~berwyned/census/articles/pumaguidelines.pdf For those new to the PUMS game an article talking about the importance of PUMS data for transportation planning can be found in the last "status report" at http://www.mcs.com/~berwyned/census/newsltr/sr0401.html#pums Since PUMS data is becoming increasing more useful in the context of transportation planning it is important for MPOs (and state DOTs) to be close to the development of the PUMAs (pums zones) in their areas--especially for the larger MPOs and for state planning. Although the process of delineating the PUMAs is left to the SDCs, MPOs and state DOTs should contact their SDC and let them know that they have an interest in participating or assisting with the process. In 1990 I know there were several MPOs that actually defined the zones in their planning areas. The SDCs can be found at http://www.census.gov/pub/sdc/www/sdctxt.html If you contact your SDC and you find that they are NOT participating in the program please let us know by contacting Nandu Srinivasan at nanda.srinivasan(a)fhwa.dot.gov ed christopher chair, trb subcommittee on census data for transportation planning
