See the link below for the 2006 ACS release schedule.
The U.S. Census Bureau will release data from the 2006 American
Community Survey (ACS) in August and September. This years data release
marks the first time that group quarters (such as prisons, college
dorms, military barracks and nursing homes) are included in the data
products. Closer to the release date, the Census Bureau will provide
guidance on making comparisons between annual ACS data products, as well
as comparisons between ACS and Census 2000 data. Data will again be
available for the nation, 50 states and the District of Columbia, Puerto
Rico, every congressional district and all counties, places and
metropolitan areas with populations of 65,000 or more.
