Description

OCC1930 reports the person's primary occupation, coded into the original 1930 census classification scheme. The 1930 scheme also includes some non-occupational activities. Generally, the primary occupation is the one from which the person earns the most money; if respondents were not sure about this, they were to report the one at which they spent the most time. Unemployed persons were to give their most recent occupation. For persons listing more than one occupation, the samples use the first one listed.

The variable OCC provides a numeric occupational classification that is identical to the OCC1930 scheme. The correspondence between the OCC and OCC1930 codes is recorded in the 1930 Occupation Codes list.
