What This Comparison Actually Tells You
Rents creates the largest separation: Boston-Cambridge-Newton is 61.8 points higher. But goods move against the overall direction, so this is a split budget rather than a clean across-the-board winner.
Walla Walla, WA and Boston-Cambridge-Newton, MA-NH sit in clearly different price tiers, separated by 9.7 RPP points. At this distance, treating the same nominal salary as equivalent would materially change purchasing power.
This route crosses the national benchmark: Boston-Cambridge-Newton is above 100 while Walla Walla is below it. That makes the move a change of price regime, not merely a rank swap.
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 Walla Walla corresponds to $109,894 in Boston-Cambridge-Newton.
