What This Comparison Actually Tells You
Boston-Cambridge-Newton, MA-NH and Riverside-San Bernardino-Ontario, CA are a photo finish on overall price level, only 1.8 RPP points apart. A salary conversion is therefore a fine adjustment, not evidence of a fundamentally different cost regime.
Rents creates the largest separation: Riverside-San Bernardino-Ontario is 19.1 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.
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 Boston-Cambridge-Newton corresponds to $98,315 in Riverside-San Bernardino-Ontario.
