This page presents the 1910 census occupational classification system recorded in the IPUMS variable OCC. 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 income and status measures recorded in the variables SEI and OCCSCORE.
