Instrument codes from this pair's BEA Regional Price Parities (overall · goods · services · rents · national benchmark 100 · purchasing-power conversion), not a ranking or recommendation.
Amherst Town-Northampton, MA and Coeur d'Alene, ID are a photo finish on overall price level, only 1.9 RPP points apart. A salary conversion is therefore a fine adjustment, not evidence of a fundamentally different cost regime.
Services creates the largest separation: Coeur d'Alene is 85.0 points lower. But rents 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.
This route crosses the national benchmark: Amherst Town-Northampton is above 100 while Coeur d'Alene is below it. That makes the move a change of price regime, not merely a rank swap.
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 Amherst Town-Northampton to $98,055 in Coeur d'Alene, but it is not a personal spending weight.
