What This Comparison Actually Tells You
Salem, OR is 7.5% more expensive than Kankakee, IL, a meaningful but not extreme shift. The move decision turns on which budget category creates the 7.3-point overall gap.
This route crosses the national benchmark: Salem is above 100 while Kankakee is below it. That makes the move a change of price regime, not merely a rank swap.
Rents leads the difference, with Salem 17.5 points higher than Kankakee. Goods, services, and rents all point in the same broad direction, making the headline comparison more transferable across household types.
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 Kankakee corresponds to $107,526 in Salem.
