A public use microdata area (PUMA) is an area with a decennial census population of 100,000 or more people for which the U.S. Census Bureau provides specially selected extracts of raw data from a small sample of long-form census records screened to protect confidentiality. These extracts are referred to as "public use microdata sample (PUMS)" files. Data users can use these files to create their own statistical tabulations and data summaries. For Census 2000, there are state-level and national PUMS files. The U.S. Census Bureau first provided PUMS information in conjunction with the 1960 census data tabulations.
Super-PUMAs (1-percent sample) comprise areas of at least 400,000 people and are aggregations of the smaller 5-percent Public Use Microdata Areas. These page size state-based maps depict Super-PUMA boundaries and codes, state boundaries, and county boundaries and names. Inset maps are used when the Super-PUMA boundaries and codes cannot be displayed clearly on the page size state-based map. In that case, the area to be inset is shaded on the state map and the Super-PUMA detail is suppressed to avoid confusion. The corresponding inset area map containing the associated Super-PUMA detail is displayed either on the same page with the state-based map or on a separate, succeeding page. The information present in these files is provided for the purposes of statistical analysis and census operations only.
