What This Comparison Actually Tells You
Rents creates the largest separation: Coeur d'Alene is 26.6 points higher. But goods move against the overall direction, so this is a split budget rather than a clean across-the-board winner.
Coeur d'Alene, ID is 3.4% more expensive than St. Louis, MO-IL, a meaningful but not extreme shift. The move decision turns on which budget category creates the 3.2-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 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 St. Louis corresponds to $103,371 in Coeur d'Alene.
