1970 Occupation Codes
This page presents the 1970 census occupational classification system recorded in the IPUMS variable OCC. The page shows each occupation category and its corresponding OCC code. The occupations are organized into several large groupings of roughly descending socioeconomic status (e.g., professionals). In addition to this contemporary system, the IPUMS codes all census years into the 1950 occupation classification scheme, recording them in the variable OCC1950. A parallel variable called OCC1990, available for the samples from 1950 onward, codes occupations into a simplified version of the 1990 occupational coding scheme. The OCC1950 and OCC1990 classifications have corresponding occupational standing measures recorded in the variables SEI, HWSEI, NPBOSS50, NPBOSS90, PRESGL, PRENT, EDSCOR50, EDSCOR90, ERSCOR50, ERSCOR90, and OCCSCORE. Our essay on "Integrated Occupation and Industry codes and Occupational Standing Variables in the IPUMS" describes how we construct harmonized occupational variables as well as occupational standing variables.
