What This Comparison Actually Tells You
Columbia, SC and Lafayette-West Lafayette, IN are a photo finish on overall price level, only 0.2 RPP points apart. A salary conversion is therefore a fine adjustment, not evidence of a fundamentally different cost regime.
Rents leads the difference, with Lafayette-West Lafayette 3.0 points lower 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.
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.
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 $99,752 in Lafayette-West Lafayette.
