What This Comparison Actually Tells You
Port St. Lucie, FL and Waterbury-Shelton, CT are a photo finish on overall price level, only 0.4 RPP points apart. A salary conversion is therefore a fine adjustment, not evidence of a fundamentally different cost regime.
Services creates the largest separation: Waterbury-Shelton is 60.5 points higher. But services and goods move against the overall direction, so this is a split budget rather than a clean across-the-board winner.
Comparable population context is incomplete for this pair, so no market-scale explanation is inferred from the price indexes.
This route crosses the national benchmark: Port St. Lucie is above 100 while Waterbury-Shelton is below it. That makes the move a change of price regime, not merely a rank swap.
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 Port St. Lucie to $99,551 in Waterbury-Shelton, but it is not a personal spending weight.
