Wages are BLS Occupational Employment and Wage Statistics estimates for May 2025 (national, state and metropolitan area), for the occupation shown. OEWS wages are straight-time gross pay: they include base pay, commissions, production bonuses and tips, and exclude overtime, shift differentials, non-production bonuses and benefits. Percentiles describe all workers in the occupation, not entry or senior levels.
- Pay at a specific employer, or for self-employed workers (OEWS covers employees).
