Dear Transportation Analysts:
With the release of 2005 ACS, the Census Bureau has included PUMAs as
a tabulation geography. You can use American FactFinder to access the
PUMA tabulations. http://factfinder.census.gov
<http://factfinder.census.gov/> The population threshold for
tabulation from 1-year data accumulation from ACS is 65,000, so a PUMA,
with a population threshold of 100,000 meets this requirement. This is
mostly a benefit to very large counties (to be able to get sub-county
tabulations), or areas with many small jurisdictions which fall under
the 65,000 population threshold.
Below is the link to the 5% PUMA maps.
Has anyone looked at the PUMA tabulations for their area yet? If so,
please share your results with this listserv. Thanks in advance!
Since PUMAs are being used as tabulation geography, there is more
incentive for transportation planners to work with their State Data
Centers when PUMAs are re-defined for the 2010 Census.
