What This Comparison Actually Tells You
Goods creates the largest separation: Walla Walla is 11.4 points higher. But rents move against the overall direction, so this is a split budget rather than a clean across-the-board winner.
Walla Walla, WA is 2.2% more expensive than Kankakee, IL, a meaningful but not extreme shift. The move decision turns on which budget category creates the 2.1-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 goods-led difference, remember that many tradable prices vary less by address than housing or labor-priced services. Use $102,204 in Walla Walla as the BEA equivalent of $100,000 in Kankakee, then replace the national basket with your own.
