What This Comparison Actually Tells You
Services creates the largest separation: Chicago-Naperville-Elgin is 70.6 points lower. But goods move against the overall direction, so this is a split budget rather than a clean across-the-board winner.
Chicago-Naperville-Elgin, IL-IN is 5% less expensive than Salinas, CA, a meaningful but not extreme shift. The move decision turns on which budget category creates the 5.4-point overall gap.
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.
Comparable population context is incomplete for this pair, so no market-scale explanation is inferred from the price indexes.
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 Salinas to $95,005 in Chicago-Naperville-Elgin, but it is not a personal spending weight.
