The figures, side by side

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.

Entangled histories

7 events in which either nation’s sourced chronicle names the other — including under earlier names of the same state. Each is the same record, with the same sources, as on its own chronicle; nothing here was written for this page.

    Renamed an "overseas province"
