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.
Lancaster, PA is 7.4% more expensive than Chattanooga, TN-GA, a meaningful but not extreme shift. The move decision turns on which budget category creates the 6.8-point overall gap.
Services leads the difference, with Lancaster 33.1 points higher than Chattanooga. 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 Chattanooga to $107,427 in Lancaster, but it is not a personal spending weight.
