1980 United States Census

The 1980 census collected the following information from all respondents:[2]

• Address
• Name
• Household relationship
• Sex
• Race
• Age
• Marital status
• Whether of Spanish/Hispanic origin or descent

It was the first census not to ask for the name of the "head of household."[3]

Approximately 16 percent of households received a "long form" of the 1980 census, which contained over 100 questions. Full documentation on the 1980 census, including census forms and a procedural history, is available from the Integrated Public Use Microdata Series.

Microdata from the 1980 census are freely available through the Integrated Public Use Microdata Series. Aggregate data for small areas, together with electronic boundary files, can be downloaded from the National Historical Geographic Information System. Personally identifiable information will be available in 2052.[4]
