During 1993, there were 6,398 employees (aged 18-80) identified by Rocky Flats as participants in epidemiologic surveillance. The composition of the work force by occupational category and salary status is given in Table 1.
The occupational categories used in the table are based on the occupation and industry codes created by the Bureau of the Census in 1980. Since workers can change occupational categories over the course of a year, workers were counted in the occupational category where they were located on January 1, 1993. A small percentage of the workers were placed in the "other" hourly category (1%). Three of these workers had no job title. The remainder were summer or co-op students.
Sixty-five percent of the workers were salaried, whereas 35% were hourly. The occupational categories with the largest number of employees were administration (25%), technical (21%), and professional (19%). Seventy-three percent of the work force was men and 27% was women. Eighty-five percent (5,420 workers) of the work force is Caucasian. The remaining 15% include African Americans, Asians, Hispanics, and Native Americans.
The work force decreased by 848 employees, a 11.7% reduction, in 1993 compared to 1992. The biggest reduction was among hourly service workers whose numbers decreased 37.6%. The only occupational categories where the work force increased in 1993 compared to 1992 were administration and other workers. There were 236 more workers in the administrative category, a 17.4% increase over 1992. The "other" hourly workers increased from 45 to 50 workers in 1993, an 11.1% increase.
