What This Comparison Actually Tells You
Rents creates the largest separation: Trenton-Princeton is 41.3 points higher. But goods move against the overall direction, so this is a split budget rather than a clean across-the-board winner.
Trenton-Princeton, NJ is 5% more expensive than Lancaster, PA, a meaningful but not extreme shift. The move decision turns on which budget category creates the 4.9-point overall gap.
This route crosses the national benchmark: Trenton-Princeton is above 100 while Lancaster 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 Lancaster corresponds to $105,010 in Trenton-Princeton.
