About this quiz and data
Population estimates from the pinned CIA World Factbook archive (CC0), checked 14 September 2026. Figures use mixed 2024/2025 reference years, labelled per row. This ranks a fixed historical snapshot, not a single-year survey or live counts.
Country names follow our catalogue. Congo means the Republic of the Congo; the Democratic Republic of the Congo belongs under D. Common alternative names are accepted. Figures are visible as clues.
Palestine: Sum of the archived West Bank and Gaza Strip profiles. Historical estimates, not a current population count.
