Thank you Robert: Apparently if the urban core "fails" at the tract
level, the analysis drops to the block level. So it would appear, all
else being equal, that no urban core in 2000 would become non-urban
under the new rules.

On the census page about the criteria
http://www.census.gov/geo/www/ua/2010urbanruralclass.html>
There is a bullet point called:
Differences Between the 2010 Census Proposed Urban Area Criteria and the
Census 2000 Urban Area Criteria [MSWord] or [TXT]
This document discusses the analysis. I cannot find that it says
whether or how many core areas might have dropped out had the proposed
criteria been used in 2000 but it does show there would have been a net
increase from 904 to 924 in initial urban cores.

Very interested in the difference. Can you point me toward the analysi
you describe?

The 2000 criteria started with block groups with the effect that some
block groups were left out that would have been included if the entire
tract were used. This was due largely to a common practice of defining
dense neighborhoods as block groups first, then having a "leftover"
block group that was everything else. The summary of differences shows
that preliminary analysis indicates that more cores would have been
identified using the initial tract method in 2000.

I am intrigued about "Use of census tracts as analysis units in the
initial phase of delineation". What does this mean? Will it mean that
the core of an urban area has to be a tract with at least 1000 pop/sq
mile? Instead of a block? If so, I can see some urban areas disapearing.

Subject: [CTPP] Fed Register notice on Proposed Urban Area Criteria for
the2010 Census
The Federal Register notice from the Census Bureau is now posted.
The due date for comments is November 22.
You may want to listen to Mike Ratcliffe's web presentation from June
11, 2010 that is available at:
http://ctpp.transportation.org/Pages/webinardirectory.aspx
----
The Census Bureau announces publication of the "Proposed Urban Area
Criteria for the 2010 Census" in the Federal Register of August 24,
2010, available on the Federal Register's website at
<http://www.gpoaccess.gov/fr/>. The Census Bureau is seeking public
comment on these proposed criteria. Comments, suggestions, or
recommendations regarding the criteria should be submitted in writing,
no later than November 22, 2010, to Timothy Trainor, Chief, Geography
Division, U.S. Census Bureau, Washington, DC 20233-7400.
The Census Bureau's urban-rural classification is fundamentally a
delineation of geographical areas, identifying individual urbanized
areas of 50,000 or more people and urban clusters of at least 2,500 and
less than 50,000 people; "rural" encompasses all population and
territory not included in urban areas. The Census Bureau's urban areas
represent densely developed territory, and encompass residential,
commercial, and other non-residential urban land uses. Additional
information about the Census Bureau's urban-rural classification is
available on the Census Bureau's website at
<http://www.census.gov/geo/www/ua/urbanruralclass.html>.
The proposed urban area criteria for the 2010 Census as well as
summaries of the proposed changes, are available on the Census Bureau's
website at < http://www.census.gov/geo/www/ua/2010urbanruralclass.html>gt;.
Changes proposed for the 2010 Census include:
* Use of census tracts as analysis units in the initial phase of
delineation
* Potential return to a maximum jump distance of 1.5 miles (the
distance was increased to 2.5 miles in the Census 2000 criteria).
* Use of land use/land cover data to identify territory containing
non-residential urban land uses or land cover that restricts urban
development, such as marshland and wetlands.
* Lowering the minimum number of enplanements (departing passengers)
from 10,000 to 2,500 to qualify airports for inclusion in urban
areas.
* Elimination of the central place concept.
* Requirement that, in addition to at least 2,500 total population,
an
area must contain at least 1,500 persons residing outside
institutional group quarters to qualify as urban.
* Splitting urban agglomerations of 1,000,000 or more population
based
on metropolitan statistical area boundaries, or, in New England,
along metropolitan New England city and town area boundaries.
For further information about the Census Bureau urban-rural
classification, or the proposed criteria for the 2010 Census, please

Geography Division, U.S.
Census Bureau, via e-mail at vincent.osier(a)census.gov or telephone at
