What This Comparison Actually Tells You
Goods creates the largest separation: Grand Rapids-Wyoming-Kentwood is 11.3 points lower. But services move against the overall direction, so this is a split budget rather than a clean across-the-board winner.
Grand Rapids-Wyoming-Kentwood, MI is 4.5% less expensive than Kennewick-Richland, WA, a meaningful but not extreme shift. The move decision turns on which budget category creates the 4.5-point overall gap.
This route crosses the national benchmark: Kennewick-Richland is above 100 while Grand Rapids-Wyoming-Kentwood 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 $95,471 in Grand Rapids-Wyoming-Kentwood as the BEA equivalent of $100,000 in Kennewick-Richland, then replace the national basket with your own.
