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 Waterbury-Shelton, CT are a photo finish on overall price level, only 0.5 RPP points apart. A salary conversion is therefore a fine adjustment, not evidence of a fundamentally different cost regime.
Rents creates the largest separation: Waterbury-Shelton is 8.4 points lower. But 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.
This route crosses the national benchmark: Amherst Town-Northampton is above 100 while Waterbury-Shelton is below it. That makes the move a change of price regime, not merely a rank swap.
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 Amherst Town-Northampton corresponds to $99,536 in Waterbury-Shelton.
