About 2001 National Industry-Specific Occupational Employment and Wage Estimates

Estimates for residual, "All Other", occupations are not available.

(1) Data for detailed occupations does not sum to the totals because the totals include data for occupations not shown separately.

(2) Annual wages have been calculated by multiplying the hourly mean wage by a "year-round, full-time" hours figure of 2,080 hours; for those occupations where there is not an hourly mean wage published, the annual wage has been directly calculated from the reported survey data.

(3) The relative standard error (RSE) is a measure of the reliability of a survey statistic. The smaller the relative standard error, the more precise the estimate.

(6) Estimates not released.
