The figures, side by sideThe dossier duel
PRESS A ROW — BOTH SPECIMENS TURN OVER TO THEIR LABELS
Each figure is the same observation, with the same source, as on the two dossiers. Every value shows the year it was observed — vintages differ by indicator and nation. A “—” is an absence in the source data, never a zero. Metric names link to the world ranking; values open the figure on its own dossier.
