What This Comparison Actually Tells You
Rents creates the largest separation: Santa Rosa-Petaluma is 60.9 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.
Merced, CA and Santa Rosa-Petaluma, CA sit in clearly different price tiers, separated by 9.5 RPP points. At this distance, treating the same nominal salary as equivalent would materially change purchasing power.
This route crosses the national benchmark: Santa Rosa-Petaluma is above 100 while Merced 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 housing-sensitive move, validate the rent gap first: HUD Fair Market Rent and the actual unit size can overturn what the blended index implies. On the BEA ratio alone, $100,000 in Merced corresponds to $109,676 in Santa Rosa-Petaluma.
