Versions

• The figures: each indicator's chart data and metadata as Our World in Data published them on 22 October 2026 (data version figures/0.1.0). They have not changed since.
• Producers, key points and country groups: from Our World in Data's full metadata and its two classification charts, taken on 23 October 2026 (figures-extras/0.1.0).
• Earlier edition: the five series that come from the World Bank's World Development Indicators, as Our World in Data's catalogue held them on 29 January 2026, beside its edition of 27 July 2026 that the figures come from. Each country or region's figure page for those indicators links its earlier edition.

When Our World in Data revises a series, this site keeps the version it took. Method.
