The raw index gap of 25.0 points matters more than the headline comparison because it flows directly into salary-equivalent math that families use for relocation, job offers, and remote-work arbitrage decisions.

The rent line carries the largest weight in the BEA methodology, so a metro with a higher rent index almost always ends up more expensive overall - Miami-Fort Lauderdale-West Palm Beach carries the heavier rent load here, and that tends to dominate household budget experience on the ground.
