What This Comparison Actually Tells You
Coeur d'Alene, ID is 4.7% less expensive than Trenton-Princeton, NJ, 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 Coeur d'Alene is below it. That makes the move a change of price regime, not merely a rank swap.
Services leads the difference, with Coeur d'Alene 41.5 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 service-heavy household, test childcare, health, and other locally supplied costs before relying on rent alone. The BEA ratio converts $100,000 in Trenton-Princeton to $95,264 in Coeur d'Alene, but it is not a personal spending weight.
