What This Comparison Actually Tells You

This route crosses the national benchmark: Portland-South Portland is above 100 while Atlantic City-Hammonton 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 Portland-South Portland to $97,054 in Atlantic City-Hammonton, but it is not a personal spending weight.
