What This Comparison Actually Tells You
Goods creates the largest separation: Olympia-Lacey-Tumwater is 11.3 points higher. But rents and services move against the overall direction, so this is a split budget rather than a clean across-the-board winner.
Olympia-Lacey-Tumwater, WA is 2.8% more expensive than Ann Arbor, MI, a meaningful but not extreme shift. The move decision turns on which budget category creates the 2.8-point overall gap.
Both metros exceed the U.S. benchmark of 100. The choice is between two national premiums, so local wages need to clear the higher baseline in either market.
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 $102,766 in Olympia-Lacey-Tumwater as the BEA equivalent of $100,000 in Ann Arbor, then replace the national basket with your own.
