Where the data comes from
- Our World in Data, used by 65 rankings. Data from Our World in Data (CC BY 4.0) and the sources it cites.
- World Bank Open Data, used by 26 rankings. Source: World Bank Open Data (CC BY 4.0).
Every ranking page states its metric definition, the source's own caveats and the capture date, and links to the original dataset. Top10Earth never estimates or edits a value. Each number is fetched from its source on a schedule, hashed, stored and ranked by software, then checked by a quality gate before it is published. If a refresh fails that gate the previous snapshot stays live and a person looks at why. Every past snapshot is kept, which is what makes the rank-history charts on each ranking page possible.
Play world and society as a quiz
Each ranking has a quiz: three minutes to name the top 10, with forgiving spelling and a shareable result card. Ten new quizzes are picked in every category each day on the quizzes page, and every past day stays playable.
