What This Comparison Actually Tells You

This route crosses the national benchmark: Norwich-New London-Willimantic is above 100 while Boise City is below it. That makes the move a change of price regime, not merely a rank swap.
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 Boise City to $102,088 in Norwich-New London-Willimantic, but it is not a personal spending weight.
