This has always been the issue. The press gets the data early as embargoed and
then the transportation folks get torpedoed and don't have a chance to respond
because they haven't seen the data. Case in point. The Atlanta Journal
Constitution ran an article about one county leading the nation with a 51 minute
travel time. Well after the story broke Joel North from GDOT and Nandu
Srinivasan used PUMs to learn the data looked funny. There were way too many
150 minute type commutes. The data did not make sense and with sampling things
can happen. Elaine Murakami then found out from Phil that indeed something was
wrong. The CB had a bad coder survey taker at the front end, going through
retraining and trying to figure out how to deal with the data.. The point
however, is if the "public agency" transportation community had the data when
the press had it we may have been able to inform what became a very misleading
article.
Another point--People do need to look at the data. I have playing with the rank
of all 775 counties that have data by their mean travel time. American
Factfinder has a lot on it.

Land of the long commute: Georgia is No. 1 in counties with time-wasting trips
to work. The sprawl makes homes affordable, but the crawl drives down the
quality of life.

Subject: [CTPP] October 3 is the next scheduled release of ACS
tablesincluding PLACE OF WORK!
How time flies! Just when you thought you were getting a handle on the
journey-to-work data from the 2005 ACS, the next round of data will
released! The next set will include Place of Work tabulations. >From the
CTPP world, these are like "CTPP Part 2" tables, where the tabulation is by
place-of-work, rather than place-of-residence. Since the 2005 ACS included
ALL counties in the sample, the place-of-work tabulations should look much
better than the 2004 ACS place-of-work tabulations (about one-third of
counties were included in the sample).
Don't forget:
1. 2005 ACS does not include Group Quarters population. That is, areas
with large military installations and/or college dormitories should expect
considerable differences when comparing to Census 2000 results.
2. The data are collected over all 12 months, therefore areas with seasonal
shifts are likely to see the greatest differences when comparing to Census
2000 results.
Good luck! Nanda Srinivasan, Ed Christopher and I are trying to wrap up our
new Profile sheets using the 2005 ACS Place-of-Residence tables, but we have
had a lot of work on calculating Margins of Error and incorporating the
results into the tables.
