On Monday the Census Bureau released what it is calling the Census 2000
Supplementary Survey (C2SS). The C2SS was a survey of 700K households
designed to test the operational feasibility of collecting long form
type data simultaneously, but separate from a decennial census. We know
this as part of the ACS (american community survey--the replacement of
the long form) development program.
Data collection for the C2SS began in November 1999 in 1,203 counties
and ran through December 2000. Residents of approximately 58,000
addresses were contacted each month. Although the survey was conducted
in only 1,203 counties, it is important to note that this size sample is
sufficient to produce data for every state in the Nation, as well as for
counties and most metropolitan areas of 250,000 in population or more.
Currently, national and statewide data has been released. you can find
all the C2SS data on the Census's Fact Finder website
and on the USA Today site. The USA today
has a sortable table of each of the 58 states showing the modes used to
go to work and travel time at
if anyone knows of any other sites doing stuff with the C2SS data feel
free to pass them along.
