What This Comparison Actually Tells You
Rents creates the largest separation: Springfield is 59.3 points lower. But services move against the overall direction, so this is a split budget rather than a clean across-the-board winner.
Springfield, MA is 6.9% less expensive than Trenton-Princeton, NJ, a meaningful but not extreme shift. The move decision turns on which budget category creates the 7.1-point overall gap.
This route crosses the national benchmark: Trenton-Princeton is above 100 while Springfield 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 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 $93,100 in Springfield.
