What This Comparison Actually Tells You
Peoria, IL and Napa, CA sit in clearly different price tiers, separated by 21.3 RPP points. At this distance, treating the same nominal salary as equivalent would materially change purchasing power.
This route crosses the national benchmark: Napa is above 100 while Peoria is below it. That makes the move a change of price regime, not merely a rank swap.
Rents leads the difference, with Napa 133.7 points higher than Peoria. Goods, services, and rents all point in the same broad direction, making the headline comparison more transferable across household types.
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 Peoria corresponds to $123,373 in Napa.
