ComparabilityAggregator is not the statistical authority: Use the source agency, source code, and methodology link when citing or reconciling with official releases.Inflation 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.
