What This Comparison Actually Tells You
Phoenix-Mesa-Chandler, AZ and Chicago-Naperville-Elgin, IL-IN are a photo finish on overall price level, only 0.3 RPP points apart. A salary conversion is therefore a fine adjustment, not evidence of a fundamentally different cost regime.
Goods creates the largest separation: Chicago-Naperville-Elgin is 12.2 points higher. But services and 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 goods-led difference, remember that many tradable prices vary less by address than housing or labor-priced services. Use $100,270 in Chicago-Naperville-Elgin as the BEA equivalent of $100,000 in Phoenix-Mesa-Chandler, then replace the national basket with your own.
