1930 Occupation Codes
This page presents the 1930 census occupational classification system recorded in the IPUMS variables OCC and OCC1930. The original occupation codes containing both alphabetic and numeric characters are preserved in OCC1930, while OCC presents the occupation codes in fully numeric form without changing the occupational categorization. This table shows the relationship between the OCC and OCC1930 codes. In addition to this contemporary system, the IPUMS codes all census years into the 1950 occupation classification scheme, recording them in the variable OCC1950. This table is also available in Excel format. 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.
