What This Comparison Actually Tells You
Dover, DE is 5.5% less expensive than Trenton-Princeton, NJ, a meaningful but not extreme shift. The move decision turns on which budget category creates the 5.7-point overall gap.
This route crosses the national benchmark: Trenton-Princeton is above 100 while Dover is below it. That makes the move a change of price regime, not merely a rank swap.
Rents leads the difference, with Dover 39.2 points lower than Trenton-Princeton. Goods, services, and rents all point in the same broad direction, making the headline comparison more transferable across household types.
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 Trenton-Princeton corresponds to $94,502 in Dover.
