DESCRIPTION 1990: The 1990 Public Use Microdata Sample (PUMS) contains household and person records for a sample of housing units that received the "long form" of the 1990 Census questionnaire. Data items include the full range of population and housing information collected in the 1990 Census, including 500 occupation categories, age by single years up to 90, and wages in dollars up to $140,000. Each person identified in the sample has an associated household record, containing information on household characteristics such as type of household and family income.
The Public Use Microdata Samples from the 1980 Census contain individual and household level information form the "long-form" questionnaires distributed to a sample of the population enumerated in the Census. Each of the PUMS files contains two types of records: "household" records and "person" records.
DESCRIPTION 2000: PUMS files have state-level Census 2000 data containing individual records of the characteristics for a 1 percent sample and 5 percent sample of people and housing units. The PUMS files contain geographic units called super-Public Use Microdata Areas (super-PUMAs), a new geographic entity for Census 2000. The state files, which may contain one or more super-PUMAs, include geographic equivalency files that show the relationship between the super-PUMA and standard Census 2000 geographic concepts (e.g., counties, etc.). The super-PUMAs are made up of a Public Use Microdata Area (PUMA) or group of contiguous PUMAs (each PUMA must have a minimum of 100,000 population). PUMAs are only identified on the 5-percent files and not on the 1-percent files.

In order to uniquely identify a person in the PUMS, PRI has created a variable ID which is a combination of the state FIP code, SERIALNO and a sequential person number within the household for each person record.
This is the 1993 re-release version of the PUMS data and was downloaded on 2/12/98 to PRI. It includes some changes from the earlier version involving the Texas file and the variables POWSTATE, MIGPUMA, PSA, MIGSTATE, POWPUMA.
