What This Comparison Actually Tells You
Auburn-Opelika, AL and Hattiesburg, MS are a photo finish on overall price level, only 0.3 RPP points apart. A salary conversion is therefore a fine adjustment, not evidence of a fundamentally different cost regime.
Services leads the difference, with Hattiesburg 7.0 points lower than Auburn-Opelika. 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 service-heavy household, test childcare, health, and other locally supplied costs before relying on rent alone. The BEA ratio converts $100,000 in Auburn-Opelika to $99,659 in Hattiesburg, but it is not a personal spending weight.
