What This Comparison Actually Tells You
Rents creates the largest separation: Chicago-Naperville-Elgin is 13.2 points higher. But services move against the overall direction, so this is a split budget rather than a clean across-the-board winner.
Chicago-Naperville-Elgin, IL-IN is 5.4% more expensive than Prescott Valley-Prescott, AZ, a meaningful but not extreme shift. The move decision turns on which budget category creates the 5.3-point overall gap.
This route crosses the national benchmark: Chicago-Naperville-Elgin is above 100 while Prescott Valley-Prescott 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 Prescott Valley-Prescott corresponds to $105,435 in Chicago-Naperville-Elgin.
