Global price index — Big Mac
Chained from the median year-over-year change across all countries with data. Base 100 in 2021.
This index is bootstrapped with The Economist's Big Mac series (2021–2026) — a real, internationally comparable price tracked over time. As the community submits more dated prices, every category gains its own real inflation curve, computed the same transparent way.
