How These Numbers Are Calculated
All wage figures come from the U.S. Bureau of Labor Statistics Occupational Employment and Wage Statistics (2024) release at bls.gov/oes. National medians are the BLS-published median wages for the trade's Standard Occupational Classification (SOC) code; metropolitan medians come from the same OEWS release at the metropolitan statistical area level. Five-year wage growth compares the current OEWS median to the same series five releases prior, expressed as a percent change. The Trade Pay Score weights raw pay (30%), wage growth (25%), employment depth (25%), and cost-of-living-adjusted purchasing power (20%) into a single 0-100 grade — read the full methodology.
Forward-looking employment projections through 2032 for both trades are published in the BLS Occupational Outlook Handbook at bls.gov/ooh. Apprenticeship pathway detail comes from the U.S. Department of Labor's apprenticeship.gov registry. All three are public-domain federal data sources.
