Frequently Asked Questions
We offer curated lists grouped by geography, size, and governance — including landlocked countries, island nations, smallest and largest by area, most and least populated, UN members, monarchies, and more.
Each list applies a specific filter to our REST Countries database (for example, 'landlocked' means no sea coastline). Results are sorted and capped where appropriate.
Country data combines REST Countries (geography, borders, government type, UN membership) with World Bank and WHO indicators shown on individual country pages.
