This data collection contains two separate data files, both of which are the results of the systematic evaluation of job worth performed by the Committee on Occupational Classification and Analysis of the National Academy of Sciences. The Committee acquired a selection of variables from the April 1971 Current Population Survey (CPS) that were gathered from a sample of households which yielded 60,441 workers in the experienced civilian labor force. The CPS survey provided detailed information about the workers and their family backgrounds, education, and employment. Part 1 contains that data augmented with Dictionary of Occupational Titles (DOT) characteristics, e.g., job classification and description, for each worker in the survey. Part 2 of this data collection is a file created by the Committee containing aggregate DOT characteristics (based on the DOT, Fourth Edition) for the 574 expanded occupation categories of the 1970 United States Census. The motivation for aggregating DOT characteristics (which exist as scores for each of 12,099 occupations) into 1970 United States Census codes was to allow researchers to relate the characteristics of occupations from the DOT to the characteristics of the individuals in those occupations gathered from the Census and survey data. The file's data -- the aggregated scores for all the workers in each of the 574 occupational categories -- are based on a variety of criteria, e.g., Specific Vocational Preparation (SVP), aptitudes, interest factors, preferences, physical demands, environmental conditions, and General Educational Development (GED).
