Watertown-Fort Drum, NY and Boise City, ID sit in clearly different price tiers, separated by 10.7 RPP points. At this distance, treating the same nominal salary as equivalent would materially change purchasing power.
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.
Comparable population context is incomplete for this pair, so no market-scale explanation is inferred from the price indexes.
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 Watertown-Fort Drum to $112,203 in Boise City, but it is not a personal spending weight.
