What This Comparison Actually Tells You
Columbia, SC and Salem, OR sit in clearly different price tiers, separated by 10.0 RPP points. At this distance, treating the same nominal salary as equivalent would materially change purchasing power.
This route crosses the national benchmark: Salem is above 100 while Columbia is below it. That makes the move a change of price regime, not merely a rank swap.
Rents leads the difference, with Salem 30.9 points higher than Columbia. 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 Columbia corresponds to $110,663 in Salem.
