Link to Census 2000 Gateway 5-Percent Public Use Microdata Sample (PUMS) Files


PUMS files have state-level Census 2000 data containing individual records of the characteristics for a 5 percent sample of people and housing units.

The PUMS files contain geographic units known as super-Public Use Microdata Areas (super-PUMAs) and Public Use Microdata Areas (PUMAs). Each super-PUMA contains a minimum population of 400,000 and each PUMA contains a minimum population threshold of 100,000. Geographic equivalency files that show the relationship between the PUMA and standard Census 2000 geographic concepts (e.g., counties, etc.) are included.
