The Louisville/Jefferson County pay distribution spans from $75,510 at the 10th percentile to $124,470 at the 90th, a 1.6× observed spread. Differences in specialization, employer, sector, location, credentials, schedule, and experience may all contribute, but OEWS does not isolate their effects.

Metro figures use establishment work location, not worker residence. BLS draws metro boundaries from the OMB MSA definitions, so Louisville/Jefferson County, KY-IN 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 KY estimate, and peer-metro rows provide distinct geographic comparisons. A published median is a benchmark, not a prediction or ceiling for one worker.
