How this page is built
2025–35 National Employment Matrix, 2025 percent of occupation (employment of the occupation in the industry divided by total employment for the occupation) at the 3-digit NAICS level, plus the Matrix government aggregate. Occupations with at least 20,000 jobs (thousands of jobs, all industries). Descriptive estimates; no causal claims. Since May 2025, OEWS publishes specific values for many wages above $239,200 a year; where BLS still publishes only “$239,200 or more”, that is what is shown. Data are in the public domain.
- Any one employer: these are national estimates for an occupation within an industry.
- Self-employed workers: OEWS counts wage and salary jobs only.
- Cause and effect: different industry wages do not mean changing industries will change anyone's pay.
