The major occupational group with the largest employment in 2000 was office and administrative support occupations, such as secretaries, clerks, and customer service representatives, with almost 18 percent of total employment.
The next largest groups, both accounting for about 10 percent of the total, were sales and related occupations and production occupations such as assemblers, machine tenders, and inspectors. These were followed by food preparation and serving-related occupations and transportation and material moving occupations, each with between 7 and 8 percent of total employment.
Together, these five major occupational groups accounted for about half of total employment in 2000.
