I am happy to answer your questions regarding the criteria as applied to
the Greenville area, but I will leave to the transportation community the
answers/responses to your questions concerning Rock Hill area. In
addition, if anyone has specific questions concerning the delineation of
their urbanized area, please send those questions direcly to us at :
You are correct in that we created two separate UAs (Greenville and
Mauldin-Simpsonville) because the criteria specify that they be separated
if their point of contiguity is no greater than a point-to-point connection
or if a hop or jump is needed to connect the areas. These criteria only
are applied where the two areas have an initial core population of 50,000
or greater, therefore, it is not applied between UA-UC or UC-UC.
With regards to the separation of the Greenville UA and the Clemson UC, the
two areas were not linked because both areas had jumped along the same road
connection between the two areas, and the distance along the remaining road
connection that separates the areas was more than 0.5 miles (more than a
permitted hop connection), requiring an addtional jump connection, which
the criteria do not permit.
Again, please let me recommend, that if you have specific questions
regarding the delineation of UAs or UCs in your area, such as the above
questions regarding Greenville/Clemson, please send them directly to us at:

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"
for UA-UC combinations and UC-UC combinations? We have what appears to be
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
small UA was "absorbed" by an adjacent larger one?

CMSA/MSA/PMSA are in the text file. 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.
