What This Comparison Actually Tells You
Harrisburg-Carlisle, PA and Flagstaff, AZ 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: Flagstaff is 14.3 points lower. 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 Harrisburg-Carlisle 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 Harrisburg-Carlisle to $101,698 in Flagstaff, but it is not a personal spending weight.
