What This Comparison Actually Tells You
Services creates the largest separation: Barnstable Town is 46.2 points higher. But services move against the overall direction, so this is a split budget rather than a clean across-the-board winner.
Barnstable Town, MA 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 4.8-point overall gap.
This route crosses the national benchmark: Trenton-Princeton is above 100 while Barnstable Town 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 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 $95,320 in Barnstable Town, but it is not a personal spending weight.
