What This Comparison Actually Tells You
Rents creates the largest separation: Boise City is 49.2 points higher. But services and goods move against the overall direction, so this is a split budget rather than a clean across-the-board winner.
Brunswick-St. Simons, GA 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 housing-sensitive move, validate the rent gap first: HUD Fair Market Rent and the actual unit size can overturn what the blended index implies. On the BEA ratio alone, $100,000 in Brunswick-St. Simons corresponds to $112,180 in Boise City.
