Notes / Gotchas

• Base period changes every 5 years (current: Oct 2019 - Sep 2020 = 100). When comparing long time series, rebasing is needed
• CPI(A) vs CPI(C) divergence indicates whether inflation hits lower-income households harder (relevant for mass-market vs premium positioning)
• “Meals bought away from home” is the single most relevant sub-index for F&B location analysis
• Data published ~3 weeks after reference month end
