What This Comparison Actually Tells You
Rents creates the largest separation: Williamsport is 34.3 points lower. But goods move against the overall direction, so this is a split budget rather than a clean across-the-board winner.
Williamsport, PA is 6.6% less expensive than Atlantic City-Hammonton, NJ, a meaningful but not extreme shift. The move decision turns on which budget category creates the 6.5-point overall gap.
Both metros remain below the U.S. benchmark of 100. This comparison chooses between two below-average price levels; “more expensive” here does not mean nationally expensive.
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 Atlantic City-Hammonton corresponds to $93,418 in Williamsport.
