What This Comparison Actually Tells You
Goods creates the largest separation: Chicago-Naperville-Elgin is 10.6 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 5.5% more expensive than Raleigh-Cary, NC, a meaningful but not extreme shift. The move decision turns on which budget category creates the 5.4-point overall gap.
This route crosses the national benchmark: Chicago-Naperville-Elgin is above 100 while Raleigh-Cary 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 goods-led difference, remember that many tradable prices vary less by address than housing or labor-priced services. Use $105,540 in Chicago-Naperville-Elgin as the BEA equivalent of $100,000 in Raleigh-Cary, then replace the national basket with your own.
