For your potential use, I extracted 3 tables from the 2008
ACS data (released by the Census Bureau yesterday) and saved as .xls
file.
Of course, you could have done this yourself, and several of
you have probably already made local data sheets.
They are: C08134: Means of Transportation to
Work by Travel Time
B08141: Means of Transportation to work by Vehicles Available
C08301: Means of Transportation to work (univariate)
I used the data download feature http://factfinder.census.gov/servlet/DownloadDatasetServlet?_lang=en
For more information about the ACS Table List, please go
here: http://www.census.gov/acs/www/Products/users_guide/index.htm
Please be aware that not all Metro Areas will have data
available for each table, since the coefficient of variation (CoV) is checked
before release.
When the table number starts with “C” it
means it is the collapsed version. Therefore, you can use the
“B” table instead with more categories, by going back into American
FactFinder, or the
For each cell, there is an ESTIMATE and a MOE (Margin of
Error). The MOE cell does NOT include “+/-“ in
the cell value (Hurrah!).
As a reminder, FHWA prepared transportation profile sheets
using Census 2000, CTPP2000 and the 2005-2007 ACS results which are posted on
the CTPP AASHTO webpage http://ctpp.transportation.org/profiles_2005-2007/ctpp_profiles.html
These profiles include State, County and Place, and do NOT include Metropolitan
Area totals. Because they use an accumulation of three years of
ACS, the population threshold is 20,000 and therefore, more geographic areas
are available.
We are not planning to update these profile sheets when the
next 3-year ACS (2006-2007-2008) data are released.
