Description: The Public Use Microdata Samples (PUMS) from the 1980 Census contain individual- and household-level information from the ''long-form'' questionnaires distributed to a sample of the population enumerated in the Census. Three different PUMS series have been prepared, each containing a number of discrete physical files. These series are called the A Sample, the B Sample, and the C Sample. The C Sample, containing 1% data, identifies census regions, divisions, 27 individual states, and the District of Columbia. Four types of areas are shown: inside central cities, urban fringe, other urban, and rural. The C sample separately identifies every urbanized area with a total population over 800,000, and roughly half of the urbanized areas between 200,000 and 800,000. Three 1-in-1,000 samples are also available, one each extracted from the A, B, and C samples. Each of the discrete PUMS files contains two types of records: ''household'' records and ''person'' records. Although the length of each of these record types is identical (193 characters), the files are hierarchical in structure, each person record has a logical and physical relationship to the household record which precedes it.
