Thursday, October 18, 2018 - 16:45


The Census Bureau has released its 2017 ACS 1-Year Public Use Microdata Sample (PUMS) Files.

The PUMS files show the full range of population and housing unit responses collected on individual ACS questionnaires, creating subsamples of ACS housing units and group quarters persons (~1% of the United States population). Data users can download these datasets and conduct custom analyses, using statistical software such as R, SPSS, Stata, or SAS.

PUMS data can be accessed via the ACS FTP site, American FactFinder, or via the Census Bureau's DataFerrett tool. DataFerrett is particularly useful for researchers who need a quick statistic or do not have access to statistical software. Read more about how the datasets are applied through ACS Data Stories.
