Perhaps someone with Census can answer these two questions. The new urban/rural classification method had some interesting results in South Carolina. One of our UAs (Greenville) was split into two UAs, with a very narrow band of "rural" area (along the I-85 corridor, where there's little or no population in the blocks adjacent to the freeway) dividing the new Mauldin-Simpsonville UA from the Greenville UA, which it was part of in 1990. I assume that the two UAs were not combined because contiguity could only have been achieved with a "hop" connection, and the urban/rural classification rule specifies that otherwise separate UAs won't be combined using a "hop". 1) Is that correct? And, 2) does the "no hop" rule apply for UA-UC combinations and UC-UC combinations? We have what appears to be a single block discontiguity between the Greenville UA and Clemson UC, also. Now, a general question for the list: The Rock Hill, SC UA lost a significant part of its 1990 urban area to Charlotte, NC. Transportation planning for the portion of the Rock Hill UA that was "lost" to Charlotte is currently handled by the Rock Hill MPO. This creates some interesting and potentially troublesome planning and political issues. Has anyone else had a similar experience, where part of a small UA was "absorbed" by an adjacent larger one?

I'm 99% sure that the Chicago PMSA was also a PDF profile but I don't want to dig into the 91meg zipped profiles for Illinois right now to find out:-) Of course only the portion of MSA/CMSA within a state is reported. There is supposed to be a national file out eventually with the full CMSAs. jim b On Wed, 29 May 2002, Patty Becker wrote: released Cook ---------------------------------------------------------------------------- ---------------------
