PUMS Data

The Bureau of the Census publishes statistics in 2 formats, tabulated statistics and public use microdata samples (PUMS).

• Tabulated data are preconfigured tables, such as those in books.

• Microdata samples reflect the individual answers of each respondent, excluding personal identifying information. Data are not compiled into tables. Users create their own tables with statistical packages, such as SPSS or SAS. This sometimes requires a good amount of statistical sophistication.
