What This Comparison Actually Tells You
Rents creates the largest separation: Charleston-North Charleston is 23.5 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.
Charleston-North Charleston, SC is 2.3% more expensive than Harrisburg-Carlisle, PA, a meaningful but not extreme shift. The move decision turns on which budget category creates the 2.3-point overall gap.
This route crosses the national benchmark: Charleston-North Charleston 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 housing-sensitive move, validate the rent gap first: HUD Fair Market Rent and the actual unit size can overturn what the blended index implies. On the BEA ratio alone, $100,000 in Harrisburg-Carlisle corresponds to $102,344 in Charleston-North Charleston.
