What This Comparison Actually Tells You
Riverside-San Bernardino-Ontario, CA and Boulder, CO are a photo finish on overall price level, only 1.2 RPP points apart. A salary conversion is therefore a fine adjustment, not evidence of a fundamentally different cost regime.
Services creates the largest separation: Boulder is 65.9 points lower. But rents 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 service-heavy household, test childcare, health, and other locally supplied costs before relying on rent alone. The BEA ratio converts $100,000 in Riverside-San Bernardino-Ontario to $98,835 in Boulder, but it is not a personal spending weight.
