What This Comparison Actually Tells You
Both metros exceed the U.S. benchmark of 100. The choice is between two national premiums, so local wages need to clear the higher baseline in either market.
Trenton-Princeton, NJ is 7% less expensive than Urban Honolulu, HI, a meaningful but not extreme shift. The move decision turns on which budget category creates the 7.8-point overall gap.
Services leads the difference, with Trenton-Princeton 75.0 points lower than Urban Honolulu. 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 Urban Honolulu to $92,988 in Trenton-Princeton, but it is not a personal spending weight.
