While the Census Bureau seeks input and comments on the criteria for delineating urban
areas, the delineation process is carried out solely by the Census Bureau. We define
urban areas for statistical purposes only-- for purposes of tabulating and presenting
statistical data for individual urban areas and the urban and rural components of the
population, housing, and land area of the nation, states, and other geographic areas.
Although we are cognizant of other agencies' particular uses of our urban areas or
urban/rural classification for implementing programs, we do ntake those uses into account
when delineating urban areas. This has been the case since the Census Bureau first began
identifying urban areas in 1910 and urbanized areas in 1950.
So, to be clear, we have no plans to release an app for delineating urban areas.

Has anyone got word of the Census Bureau releasing any GIS tools that will aid in creating
the Urban Area using the criteria? It would be disappointing to spend the time coding a
model only to find out there was already an app for that. Thanks.

Garth--I am posting this to the Listserve since it is a common question
and its important that we update everyone. You are right that we have
been waiting for the Federal Register notice announcing the criteria
that the Census Bureau will use for defining Urbanized area. You are
equally right that it was expected in the fall of 2009. Unfortunately
it has not come out yet and we are hoping to see it by the Spring of
2010. From what I have been told it has been drafted and is wending its
way up the Census Bureau hierarchy to get all the approvals and sign
offs. for now we can sit and wait for the process to do its thing.
Incidentally, I am working with Mike Ratcliffe from Census Geography on
a workshop that we will be having at the GIS-T conference in April where
we will have the whole issue of Urbanized Area criteria on the agenda.
Needless to say we are both hopeful that the Register notice will
be out by then.

I was wondering if you have any new information on the Census' proposed criteria
for determining urban cluster and urbanized area boundaries for 2010? I recall
from both a June 2009 webinar as well as the September 2009 CTPP Newsletter that
the proposed criteria would be published in Fall 2009. Has this occurred? If
so, what Federal Register issue should one consult? I'd appreciate any
clarification you could provide.
