Essential grocery expenses (Engels Index) reveal a major structural gap (Barcelona: 15.31% vs Valletta: 25.49%), marking food inflation as a critical stress differentiator.

Across southern European metros in Portugal, Italy, and Spain, food expenditure consumes a heavy 20–25% slice of local median wages. Current baseline food metrics draw from localized dining samples on Numbeo, which can be inflated by tourist-heavy dining districts. Primary baseline food shares will be recalibrated as standardized regional grocery baskets are established.
