What This Comparison Actually Tells You
Rents creates the largest separation: Salisbury is 24.8 points lower. But services move against the overall direction, so this is a split budget rather than a clean across-the-board winner.
Salisbury, MD is 7.7% less expensive than Chicago-Naperville-Elgin, IL-IN, a meaningful but not extreme shift. The move decision turns on which budget category creates the 8.0-point overall gap.
This route crosses the national benchmark: Chicago-Naperville-Elgin is above 100 while Salisbury 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 Chicago-Naperville-Elgin corresponds to $92,299 in Salisbury.
