Population data and source
Uses population estimates from the archived CIA World Factbook, checked 14 September 2026. Reference years are mixed (the 2024 or 2025 estimate published for each country), so this ranks a fixed snapshot, not live counts. Other sources can swap close neighbours in the list.
Ranks the 197 countries of our world quizzes: the 193 UN member states plus Vatican City, Palestine, Kosovo and Taiwan. Dependent territories such as Greenland, Puerto Rico and Hong Kong are not ranked, and each country counts once, with its whole area and population.
Microstates count like any other country. Vatican City's figure is the archive's 2024 estimate of about 1,000 people.
Countries with exactly the same published figure share a rank. If a tie straddled the last place, every tied country would be accepted; none does in this snapshot.
