What This Comparison Actually Tells You
Rents creates the largest separation: Trenton-Princeton is 29.6 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 3.2% more expensive than Allentown-Bethlehem-Easton, PA-NJ, 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: Trenton-Princeton is above 100 while Allentown-Bethlehem-Easton 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 Allentown-Bethlehem-Easton corresponds to $103,213 in Trenton-Princeton.
