Greenland or Greenlands?
It is a widely accepted theory that under the permanent ice sheet Greenland is actually composed of three islands, but the unified landmass is considered a single entity.
Less than 30% of the Earth's surface is occupied by land, seven giant continents make up the overwhelming majority. But a considerable number of islands dot the Earth's surface, and are in fact some of the most populous regions in the world.

The seven continents are technically islands, since they are landmasses surrounded entirely by water. However, they are not usually considered among the largest islands in the world, since even the smallest continent, Australia, is more than four times larger than the largest 'island', Greenland. By the strict definition though, the seven continents are actually the largest islands in the world.

Asia is also the most populous continent, and hence the most populous island, in the world.

Moving on to non-continental islands, here are the world's largest islands in order.

These are the largest islands in the world by area. However, in human terms, just because they are the largest does not mean they are suitable for habitation. Some of the largest islands in the world are also some of the most sparsely populated regions in the world. Greenland and Baffin Island, for instance, lie close to or in the Arctic circle, and hence only have sporadic human habitation. In contrast, tropical islands are some of the most densely populated islands in the world. Here are the largest islands in the world by population.

Note: The numbers are rounded off to the nearest hundred thousand.
