What This Comparison Actually Tells You
Oklahoma City, OK and Gulfport-Biloxi, MS are a photo finish on overall price level, only 0.4 RPP points apart. A salary conversion is therefore a fine adjustment, not evidence of a fundamentally different cost regime.
Rents creates the largest separation: Gulfport-Biloxi is 6.0 points lower. But goods and services move against the overall direction, so this is a split budget rather than a clean across-the-board winner.
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 Oklahoma City corresponds to $99,555 in Gulfport-Biloxi.
