On December 4, the U.S. Census Bureau released the 2009-2013 American Community Survey (ACS) five-year estimates. The ACS is a survey of more than 3.5 million households that includes social, demographic, housing, and economic characteristics. The data are released as one, three, and five-year estimates. The ACS five-year estimates (2009-2013) are available down to the census tract and block group level.
For the first time, block group level data will be available via the Census Bureau’s American FactFinder. In past years, these data were only available through the Census Bureau’s FTP (file transfer protocol) site. In addition, this data release also includes a new edition of Census Explorer interactive maps.
The 2011-2013 ACS three-year Public Use Microdata Sample (PUMS) files were also released on December 4. PUMS files contain records on a subsample of housing units and information from the ACS questionnaire; PUMS data are used to run custom tabulations. The 2013 1-year PUMS file was released on October 23.
