U.S. Census Bureau Releases First Set of 5-Year American Community Survey Estimates
"The U.S. Census Bureau today released 5-year American Community Survey (ACS) estimates for the first time, making available social, economic, housing and demographic statistics for every community in the nation.

Up until now, small geographic areas had to rely on outdated 2000 Census figures for detailed information about the characteristics of their communities. Consisting of about 11.1 billion individual estimates and covering more than 670,000 distinct geographies, the 5-year ACS estimates give even the smallest communities more timely information on topics ranging from commute times to languages spoken at home to housing values.

"The ACS represents the first time such a massive compilation of data estimates for small geographic areas is available," said Census Bureau Director Robert Groves. "These estimates deliver on our commitment to Congress to provide timely statistics on our communities and our economy, allowing for a more efficient government."

The data released today are based on a rolling annual sample survey mailed to about 3 million addresses between Jan. 1, 2005, and Dec. 31, 2009. By pooling several years of survey responses, the ACS can generate detailed statistical portraits of smaller geographies. The Census Bureau will release a new set of 5-year estimates every year, giving these communities a powerful tool to track local trends over time.

Public officials, including mayors and governors, and private organizations such as chambers of commerce, rely on ACS estimates on education, housing, jobs, veteran status and commuting patterns to help them make informed decisions that will affect their community, such as where to build new schools, hospitals and emergency services...

The new 2005-2009 ACS estimates are not related to the 2010 Census population counts that will be released Dec. 21. The ACS complements the decennial count and provides estimates of population characteristics that are far more detailed than the basic demographic information that will be released from the 2010 Census, which will be available starting in February..."
