For the 1971, 1976, and 1981 Censuses, the occupational data are coded according to the CCLO (ABS 1961).
In the mid-1980s the CCLO, which had been used by the ABS to code occupations in censuses and official surveys since the 1960s, was superseded by a new classification that paid greater attention to differences in skill level than to industrial sector and the materials used by workers.
