Top 10 Least Densely Populated Countries Quiz — Rules & What Counts
Name the ten emptiest countries on Earth — the sovereign states with the fewest people per square kilometer. The winner averages about two people per km²; for comparison, the global average is around 60.
This quiz rewards a specific insight: emptiness comes in flavors. Deserts, steppe, tundra, and rainforest each contribute entries, and two continent-sized countries with tens of millions of citizens make the list purely because their landmass dwarfs their populations. It's a very different mental exercise from naming small or obscure countries.
How to play
Location pins are hidden — knowing where to look would be most of the answer. A numbered 1–10 rail shows your progress; countries appear on the map as you get them.
Type anywhere; the answer bar auto-focuses and matches as you type.
Spelling is lenient, so close attempts and common names count.
Count-up timer; give up reveals what's left and records your score.
What counts in this quiz
Exactly 10 sovereign countries, ranked by population density (people per km²) from lowest up.
Mongolia leads at roughly 2 people per km².
Density is the only criterion — so vast countries with big absolute populations qualify right alongside sparse mid-sized ones.
What's not included — and why
Greenland is far emptier than anything on this list (~0.03 people/km²) but is an autonomous territory of Denmark, not a sovereign state — so it doesn't qualify.
Antarctica has no permanent population at all, but it's a continent governed by treaty, not a country.
Western Sahara is similarly sparse, but its sovereignty is disputed, so it's left off.
Good to know
Mongolia has roughly as many horses as people — and about ten times more livestock than humans.
Two of the entries also appear in the world's top 10 for forest coverage — empty and green often go together.
The list spans six continents, proving there's no single recipe for emptiness: ice, sand, steppe, and jungle all work.
