Hi Chuck and CTPP-listserv members:
First, thank you to Chuck for his long post, and issues relating to
counting workers using different sources.
At the end of his email he wrote: " We would love to have data by
PUMA-of-work, but I don't think that's coming this year....)"
He is correct. The "Place of Work" tabulations to be released on
October 3 will NOT have PUMA-of-work, because the standard workplace
coding does not extend to detailed geography, but stops after
STATE/COUNTY. That is, if sufficient information is provided by a
respondent, the automated geocoding will include geocoding to census
block. However, due to many factors, mostly attributable to
"incomplete" responses, only about 75% of workplaces are sufficiently
coded to small geography. (Since many PUMAs use census tract boundaries,
the geocoding would need to be at least to tract geography.) Until a new
workplace allocation program is developed and implemented, more detailed
workplace geography will not be available for the remaining 25%. So,
until that occurs, PUMA-of-work cannot be tabulated in the ACS.
At the end of FY06, I was able to get a small research project (with
FHWA funds) to work with the Census Bureau to explore improvements to
the workplace allocation program that was implemented for CTPP2000. I
don't know if the contract between the 2 agencies has been signed yet!
However, this is exploratory research, and IMPLEMENTATION to the ACS
data files would need to be covered by a future CTPP (assuming there is
a new pooled fund for CTPP!).
