Abstract:
|
The transportation data community has been one of the largest users of the Decennial Census Long Form. Using the last four decennial census results (1970 through 2000), the transportation community has commissioned a custom tabulation called the Census Transportation Planning Products (CTPP). Any future CTPP will now use the ACS results. A welcome addition to the ACS standard tabulations are workplace-based tables. Ideas for improving the utility of 3-year ACS data for the transportation community include: 1) adding a home-to-work flow tabulation, 2) adding a home-to-work distance variable calculated using transportation road network files, 3) establishing a geographic unit with nation-wide coverage for 3-year ACS tabulations using 2010 census tracts as building blocks, 4) finding alternatives to data suppression for both the 1-year and 3-year ACS standard and custom tabulations.
