What This Comparison Actually Tells You
Services creates the largest separation: Portland-South Portland is 26.5 points higher. But goods move against the overall direction, so this is a split budget rather than a clean across-the-board winner.
Portland-South Portland, ME is 3.3% more expensive than Harrisburg-Carlisle, PA, a meaningful but not extreme shift. The move decision turns on which budget category creates the 3.2-point overall gap.
This route crosses the national benchmark: Portland-South Portland is above 100 while Harrisburg-Carlisle is below it. That makes the move a change of price regime, not merely a rank swap.
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 Harrisburg-Carlisle to $103,252 in Portland-South Portland, but it is not a personal spending weight.
