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.
Trenton-Princeton, NJ and Baltimore-Columbia-Towson, MD are a photo finish on overall price level, only 1.3 RPP points apart. A salary conversion is therefore a fine adjustment, not evidence of a fundamentally different cost regime.
Rents creates the largest separation: Baltimore-Columbia-Towson is 16.9 points lower. But rents and services 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.
Both metros exceed the U.S. benchmark of 100. The choice is between two national premiums, so local wages need to clear the higher baseline in either market.
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 Trenton-Princeton corresponds to $101,267 in Baltimore-Columbia-Towson.
