ComparabilityInflation baskets and base periods differ: Compare growth rates or normalized indexes, and prefer the same concept family when comparing countries or providers.Seasonal-adjustment status needs attention: Prefer same-adjustment comparisons, or transform to year-over-year changes before cross-series comparison.Revision evidence is not a full historical vintage archive: Use this as current-value or captured-forward evidence unless the series is explicitly labelled source-native vintage.
