Services leads the difference, with Walla Walla 24.3 points higher than Twin Falls. Goods, services, and rents all point in the same broad direction, making the headline comparison more transferable across household types.

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 Twin Falls to $106,960 in Walla Walla, but it is not a personal spending weight.
