What This Comparison Actually Tells You
Rents creates the largest separation: Napa is 89.0 points higher. But goods move against the overall direction, so this is a split budget rather than a clean across-the-board winner.
Modesto, CA and Napa, CA sit in clearly different price tiers, separated by 8.4 RPP points. At this distance, treating the same nominal salary as equivalent would materially change purchasing power.
Both metros exceed the U.S. benchmark of 100. The choice is between two national premiums, so local wages need to clear the higher baseline in either market.
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 Modesto corresponds to $108,113 in Napa.
