Local and national wages differ for reasons beyond how well a job pays — cost of living, the mix of employers, and local demand for the occupation all move the California range relative to the national one.

Computed over the 403 of 444 people in this role paid at least $25,000in base salary. The rest are part-year or part-time records, whose actual pay isn’t comparable to a full-time annual wage.

Median total compensation for this role at Transportation is $84,517, which includes overtime and employer-paid benefits. The benchmark above excludes both, so total compensation is deliberately not compared against it.

Benchmark: U.S. Bureau of Labor Statistics, Occupational Employment and Wage Statistics (May 2025). BLS Occupational Employment and Wage Statistics (OEWS) covers all employers in the area — private, non-profit, and government alike — so this is a comparison against the whole local labor market for the occupation, not against private-sector pay. OEWS wages are straight-time pay and exclude overtime, shift differentials, and employer-paid benefits, so the government figure shown here is base pay on the same basis. Total compensation is not comparable to it. Job titles are matched to the closest standard occupation, so the comparison is between similar work rather than an identical job classification.
