How to read these figures
Offered and prevailing wages are employer-reported on each DOL filing, annualized to year rates. The average mixes experience levels, localities, and years.
The benchmark is the BLS Occupational Employment Statistics national median for this occupation, latest available year. An average set against a median: a few very high offers pull the average up.
A certified filing is an approved application, not a confirmed hire. These comparisons are screening measures, not wage-law findings.
Data sources & methodology ↗Signed gaps: a negative % sits below the benchmark; a positive % sits above.
