UOCC

Usual occupation

Description

UOCC reports the sample-line person's "usual" occupation. The instructions to enumerators defined the person's usual occupation as "that occupation at which he has worked longest during the past ten years and at which he is still physically able to work." Used in conjunction with OCC, which indicates the respondent's current occupation, UOCC allows users to identify persons currently working at an occupation different from their usual one.

Comparability

This variable is only available for 1940. UOCC (and its recoded form, UOCC95) is the only variable for 1940 indicating an occupation for persons who were not in the labor force (working, temporarily absent from a job, or looking for work) in the week prior to the census but who had worked in the past. The 1950 variable ROCC similarly supplies an occupation for previously-employed persons not in the labor force in the week prior to the census. Beginning in 1960, the census collected occupational data (in OCC) not only for persons currently in the labor force, but also for all persons who had worked during a specific reference period (within the past 10 years for 1960-1970, within the past five years for 1980-2000 and the ACS). (See OCC for further discussion.)
