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.
