About May 2003 National, State, and Metropolitan Area Occupational Employment and Wage Estimates

To see profiles of other occupations, select from the major groups below:

These estimates are calculated with data collected from employers in all industry sectors in metropolitan and non-metropolitan areas in every State and the District of Columbia. The top five employment and wage figures are provided above. The complete list is available in the downloadable Excel files(XLS).

Percentile wage estimates show the percentage of workers in an occupation that earn less than a given wage and the percentage that earn more. The median wage is the 50th percentile wage estimate—50 percent of workers earn less than the median and 50 percent of workers earn more than the median. More about percentile wages.


(1) Estimates for detailed occupations do not sum to the totals because the totals include occupations not shown separately. Estimates do not include self-employed workers.

(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.
