What This Comparison Actually Tells You
Rents creates the largest separation: Harrisburg-Carlisle is 60.7 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.
Harrisburg-Carlisle, PA is 6.2% less expensive than Boulder, CO, a meaningful but not extreme shift. The move decision turns on which budget category creates the 6.6-point overall gap.
This route crosses the national benchmark: Boulder 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 Boulder corresponds to $93,772 in Harrisburg-Carlisle.
