Methodology & Assumptions

City-level metrics (median home price, median rent, median household income, property tax rate, COL index, commute, unemployment, median age) are sourced from Zillow ZHVI/ZORI[1], Census ACS 5-year estimates[2], BEA Regional Price Parities[3], Tax Foundation[4], and BLS Local Area Unemployment Statistics[5].

The Cost of Living Index uses 100 = national average (C2ER methodology[6]): values above 100 indicate a city is more expensive than the national average, below 100 less expensive.

Salary equivalence uses the ratio adjustedSalary = salary × (colDestination / colOrigin). This accounts for cost-of-living differences but does not model state income tax variation, which can be significant.

Annual property tax is computed as medianHomePrice × propertyTaxRate. Actual assessed value may differ from sale price. Effective rates vary within a metro; these are metro-wide medians.

Commute-hours calculations assume 250 working days/year and a round-trip commute. "Tied" in the comparison table means values within ±1% of each other.

Last reviewed reflects the maximum retrievedAt timestamp across every sourced dataset feeding this page. When any source refreshes, the next ISR revalidation (every 24 hours) picks the new date.
