What percentage of people in the world live on an island?

The correct choice reflects that approximately 10% of the global population lives on islands. This figure represents a significant portion of humanity, considering the vast number of islands that exist worldwide, including both large landmasses and smaller, lesser-known examples. Many island populations tend to be densely populated, especially in regions like Southeast Asia, the Caribbean, and the Pacific, contributing to this percentage.

This statistic is relevant for various fields, including geography, ecology, and social studies, as it helps to understand population distribution and the unique challenges faced by island communities. These challenges can include limited resources, risks from climate change, and distinct cultural dynamics that arise due to geographic isolation.
