Metro figures use establishment work location, not worker residence. BLS draws metro boundaries from the OMB MSA definitions, so Riverside-San Bernardino-Ontario, CA covers the central city plus outlying counties tied to the metro economically. OEWS includes straight-time pay, tips, commissions, incentive pay, and production bonuses. It excludes employer health and retirement benefits, overtime premiums, stock compensation, signing bonuses, and other nonproduction bonuses. The same occupation's national profile, statewide CA estimate, and peer-metro rows provide distinct geographic comparisons. A published median is a benchmark, not a prediction or ceiling for one worker.
