What This Comparison Actually Tells You
St. George, UT is 5.7% less expensive than Trenton-Princeton, NJ, a meaningful but not extreme shift. The move decision turns on which budget category creates the 5.9-point overall gap.
This route crosses the national benchmark: Trenton-Princeton is above 100 while St. George is below it. That makes the move a change of price regime, not merely a rank swap.
Rents leads the difference, with St. George 36.9 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 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 $94,322 in St. George.
