The American Community Survey (ACS) Public Use Microdata Sample (PUMS) is available in a linked data format using the Resource Description Framework (RDF) data model via Amazon S3. This data is made available by in partnership with the U.S. Census Bureau.

This American Community Survey (ACS) Public Use Microdata Sample (PUMS) release is a set of untabulated records about individual people and housing units from years 2014 and 2015. The Census Bureau primarily produces microdata releases so that data users can create custom tables that are not available through pretabulated (or summary) ACS data products. This microdata release, in contrast to ACS summary files, includes population and housing unit records with individual response information such as relationship, sex, educational attainment, and employment status.

The data can be used for research projects, regression analysis, modeling applications, and application development. The linked data can be loaded into open-source graph database platforms running on EC2 and queried with the SPARQL query language. In addition to the data files, the PUMS metadata has been included as an RDF ontology.
