1920 Occupation Codes

(Back to Occupation Codes)

This page presents the 1920 census occupational classification system recorded in the IPUMS variable OCC. This system is also used to classify occupations for 1910. The page shows each occupation category and its corresponding OCC code. The occupations are grouped into several large industrial groupings (e.g., agriculture). In addition to this contemporary system, the IPUMS codes all census years into the 1950 occupation classification scheme, recording them in the variable OCC1950. The OCC1950 classification has corresponding occupational standing measures recorded in the variables SEI, NPBOSS50, PRESGL, EDSCOR50, ERSCOR50, 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.
