Sources & methods
Start with the original records. These are the primary sources behind this edition.
Traceable, dated and appropriately cautious.
We favour official government, statistical and institutional sources. Every figure should retain its reporting period, unit, geography, publication status and definition. We do not turn a press announcement into an outcome, substitute a proxy without labeling it, or convert missing data into zero.
