How is occupation/industry harmonized across various NAPP censuses?
Occupation and industry are among the most important variables for analyses of comparative social and economic structure because these censuses provide few alternative indicators of socioeconomic status or labor-force participation. The national statistical agencies employed quite different classification systems. With access to the individual-level occupational responses for all people in the censuses, we have coded occupations into a common classification system based on the HISCO classification scheme. In Great Britain, Norway, and the United States, we also have coded occupations into domestic coding schemes.
