About this estimate
These figures are survey estimates from the BLS Occupational Employment and Wage Statistics program — modeled from employer reports collected over three years and benchmarked to May 2025. They describe what employers in this area currently pay across all industries, not what any individual worker will be offered.
Employment counts wage-and-salary jobs in the occupation (self-employed workers are excluded). Estimates carry sampling error; percentile wages are rounded by BLS. Some values are suppressed by BLS for confidentiality or quality — suppressed values appear here as “not published”, never as zero. Read the full methodology.
