In some cases, employment estimates could not be provided. Wages for the OES survey are straight-time gross pay, exclusive of premium pay. Excluded are back pay, jury duty pay, tips, overtime pay, severance pay, shift differentials, nonproduction bonuses, and tuition reimbursements. In most cases, the wages provided are hourly, however, for some occupations, such as teachers, wages are annual. The OES survey collects wage data in 11 intervals.
Employers report the number of employees in an occupation per each wage range.
Industries that do not typically employ workers in a given occupation are not included in the calculation of the mean and median wage. Hourly Wage is the estimated total wages for an occupation divided by its weighted survey employment. A winsorized mean procedure is used to estimate mean wage rates. The mean wage value for the upper open-ended wage interval is its lower bound. These interval mean wage values are then attributed to all workers reported in the interval.
