About the InflationRank Score
The InflationRank Score is a proprietary 0–100 composite that summarizes a place's cost-of-living and economic conditions on a familiar A–F grading scale. Higher scores reflect a better cost-of-living-adjusted economic situation.
The composite weighs three dimensions sourced from federal government datasets: cost level (how local prices compare to the national average), inflation pressure (recent direction and pace of cost movements), and income resilience (real, cost-adjusted earning power of local residents). The score is anchored to the U.S. national average and reviewed annually as federal data refreshes.
Underlying data is drawn from authoritative federal economic agencies and public housing datasets. See full data sources →
