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 is 6.6% more expensive than Rockford, IL, a meaningful but not extreme shift. The move decision turns on which budget category creates the 6.1-point overall gap.
Services leads the difference, with Merced 69.0 points higher than Rockford. 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 Rockford to $106,642 in Merced, but it is not a personal spending weight.
