Series-level selection: for each country the whole series comes from the highest-priority source that has any non-forecast value for it. If a lower-priority source is more than three years fresher, the freshest source wins instead. Non-chosen values are kept as alternatives, never discarded.

Countries without data

Typical reasons: the source does not survey small territories or micro-states; the statistical office reports with a lag of one to three years; the series is only compiled for member countries of the source organisation (OECD, EU, Eurostat); or a value exists but failed validation and is quarantined rather than shown.
