It should be noted that this grouping of occupations (occupational categories) is different from the other "major occupation groups" appearing in most parts of the codebook. In order to classify occupations into "major occupation groups," information on occupation, industry, and class of worker is required. Whenever industry or class of worker is not ascertained for a particular job, the grouping of occupations is the occupational grouping from the 1970 Census.
