What This Comparison Actually Tells You
Hilton Head Island-Bluffton-Port Royal, SC and Harrisburg-Carlisle, PA are a photo finish on overall price level, only 0.6 RPP points apart. A salary conversion is therefore a fine adjustment, not evidence of a fundamentally different cost regime.
Services creates the largest separation: Harrisburg-Carlisle is 20.0 points higher. 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 remain below the U.S. benchmark of 100. This comparison chooses between two below-average price levels; “more expensive” here does not mean nationally expensive.
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 Hilton Head Island-Bluffton-Port Royal to $100,646 in Harrisburg-Carlisle, but it is not a personal spending weight.
