What This Comparison Actually Tells You
Rents creates the largest separation: Norwich-New London-Willimantic is 41.4 points lower. But services move against the overall direction, so this is a split budget rather than a clean across-the-board winner.
Norwich-New London-Willimantic, CT is 2.7% less expensive than Trenton-Princeton, NJ, a meaningful but not extreme shift. The move decision turns on which budget category creates the 2.7-point overall gap.
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.
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 $97,349 in Norwich-New London-Willimantic.
