What This Comparison Actually Tells You
Farmington, NM and Sumter, SC 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 Sumter 9.4 points higher than Farmington. 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 Farmington to $100,357 in Sumter, but it is not a personal spending weight.
