The U.S. Census Bureau has released American Community Survey
(ACS) data products in the form of 1year estimates for 2005, 2006, and
2007, and 3year estimates for the period of 20052007. Annual updates
of these products are planned. Specifically, in 2009 and 2010, the
Census Bureau will publish 1year estimates for the 2008 ACS and the
2009 ACS, and 3year estimates for the 20062008 ACS and 20072009 ACS,
respectively. Beginning in late 2010, the Census Bureau plans to
introduce 5year data products covering the period of 20052009. The
Census Bureau is proposing to modify its current line of data products
to accommodate the 5year estimates and is requesting comments from
current and potential users of ACS data products to help guide this
modification. The release of the 5year estimates will achieve a goal
of the ACS to provide small area data similar to the data published
after Census 2000, based on the longform sample. Plans for the
