About This Data

Wage figures on this page come from the U.S. Bureau of Labor Statistics (BLS) Occupational Employment & Wage Statistics (OEWS) survey, May 2025 release. OEWS surveys roughly 1.1 million establishments annually. It is the most comprehensive employer-reported wage dataset in the United States.

P10 through P90 percentiles represent the wage distribution across all surveyed employers (not self-reported by workers). Geographic adjustments use BLS-derived cost multipliers calibrated from regional wage variation.

Wages are estimates. Individual compensation depends on experience, education, employer size, industry, and negotiation. Use this as benchmark context, not absolute ground truth.
