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.
Knoxville, TN is 6.2% less expensive than Harrisburg-Carlisle, PA, 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 Knoxville 36.2 points lower than Harrisburg-Carlisle. 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 Harrisburg-Carlisle to $93,836 in Knoxville, but it is not a personal spending weight.
