The Public Use Microdata Sample files, or PUMS, are a sample of the actual responses to the American Community Survey and include most population and housing characteristics. These files provide users with the flexibility to prepare customized tabulations and can be used for detailed research and analysis. Files have been edited to protect the confidentiality of all individuals and of all individual households. For an overview of the file, please see the American Community Survey PUMS overview.
The 2005–2007 American Community Survey Three-Year PUMS file contains the same sample of actual responses provided in the 2005, 2006, and 2007 One-Year PUMS files. For an overview of the files, please see the American Community Survey Multiyear PUMS overview.
The one-year 2007 PUMS file is also available (see left menu).
