What This Comparison Actually Tells You
Flagstaff, AZ and Allentown-Bethlehem-Easton, PA-NJ are a photo finish on overall price level, only 0.4 RPP points apart. A salary conversion is therefore a fine adjustment, not evidence of a fundamentally different cost regime.
Services creates the largest separation: Allentown-Bethlehem-Easton is 13.8 points higher. But services and 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.
This route crosses the national benchmark: Flagstaff is above 100 while Allentown-Bethlehem-Easton is below it. That makes the move a change of price regime, not merely a rank swap.
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 Flagstaff to $99,644 in Allentown-Bethlehem-Easton, but it is not a personal spending weight.
