What This Comparison Actually Tells You
Philadelphia-Camden-Wilmington, PA-NJ-DE-MD and Ann Arbor, MI are a photo finish on overall price level, only 1.7 RPP points apart. A salary conversion is therefore a fine adjustment, not evidence of a fundamentally different cost regime.
Services creates the largest separation: Ann Arbor is 16.2 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 Philadelphia-Camden-Wilmington to $98,368 in Ann Arbor, but it is not a personal spending weight.
