IND50LY recodes information contained in the variable INDLY into the 1950 Census Bureau industrial classification system. IND50LY provides consistent occupational codes for the jobs respondents reported working during the previous calendar year, for 1968 on. Information on industry during the previous year is given as it appeared in the original survey data in INDLY. For both INDLY and IND50LY, respondents were to report the jobs they held for the longest time during the previous year.

The industry of persons employed at the time of the survey is reported in IND, and this information is recoded into the consistent 1950 industrial classification system in IND1950. IND and IND1950 also provide information about the most recent jobs of persons not employed at the time of the survey.


Apart from universe changes, IND50LY is consistent from 1968 forward. Prior to 1968, too few industrial codes were used to allow recoding into the 1950 classification scheme.
