What This Comparison Actually Tells You
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.
Merced, CA and Sumter, SC sit in clearly different price tiers, separated by 10.3 RPP points. At this distance, treating the same nominal salary as equivalent would materially change purchasing power.
Services leads the difference, with Sumter 71.0 points lower than Merced. 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 service-heavy household, test childcare, health, and other locally supplied costs before relying on rent alone. The BEA ratio converts $100,000 in Merced to $89,565 in Sumter, but it is not a personal spending weight.
