I have
attached Q&A document using materials from the chat area.
The CTPP previously
used the decennial Census "long form," but the American Community Survey (ACS)
has replaced the "long form" and the 2010 Census is a short-form only
census. For people who need basic information about the ACS, I
recommend the Census Bureau's COMPASS series.
Among the several
presentations are an overview and one on data products.
Some of the
questions have been modified from the 2005 implementation of the ACS. The
questions on disability were changed in 2008.
Here is a link to
the NCHRP report 588: A Guidebook for Using ACS Data for Transportation
Planning, completed by Cambridge Systematics in 2007.
