How the comparisons are calculated
Metro comparisons use each area's BLS OEWS May 2025 median wage across all occupations, HUD's FY2027 one-bedroom Fair Market Rent, and the state and local income tax a single filer owes on $75,000 under 2026 rules. "Median buys more in" divides each median by the area's living-cost index from the EPI Family Budget Calculator; it reads "Not published" where BLS or EPI publishes no figure for the area.
Occupation comparisons use national BLS OEWS medians and job counts. Each comparison page goes further: the occupations both metros publish wages for, or each occupation's 10th to 90th percentile pay and the metros where both are published.
