All 51 states (+DC) ranked by MERIC cost-of-living index. Most expensive first.
The most expensive states pay for that cost with concentrated economies (tech, finance, federal payroll), tight housing supply, and structural constraints (geography, regulation).
Hawaii (186.9) leads by a wide margin — every imported good carries shipping costs. DC, Massachusetts, California, and New York round out the top 5 with housing as the dominant driver.
High-COL states often have higher wages too — the question is whether the ratio works for your specific job and family.
