What This Comparison Actually Tells You
Rents creates the largest separation: Kansas City is 25.4 points lower. 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 and Kansas City, MO-KS sit in clearly different price tiers, separated by 11.1 RPP points. At this distance, treating the same nominal salary as equivalent would materially change purchasing power.
This route crosses the national benchmark: Chicago-Naperville-Elgin is above 100 while Kansas City 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 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 Chicago-Naperville-Elgin corresponds to $89,332 in Kansas City.
