What This Comparison Actually Tells You

Lewiston, ID-WA and Peoria, IL are a photo finish on overall price level, only 0.1 RPP points apart. A salary conversion is therefore a fine adjustment, not evidence of a fundamentally different cost regime.

Services creates the largest separation: Peoria is 17.9 points higher. But rents and goods move against the overall direction, so this is a split budget rather than a clean across-the-board winner.

Comparable population context is incomplete for this pair, so no market-scale explanation is inferred from the price indexes.

Both metros remain below the U.S. benchmark of 100. This comparison chooses between two below-average price levels; “more expensive” here does not mean nationally expensive.

For a service-heavy household, test childcare, health, and other locally supplied costs before relying on rent alone. The BEA ratio converts $100,000 in Lewiston to $100,078 in Peoria, but it is not a personal spending weight.
