Fun Global Geography Trivia: 18 Facts About Islands
Islands have always captivated human imagination and interest, from tiny uninhabited specs in vast oceans to massive landmasses supporting millions of inhabitants. This collection of 18 fascinating facts about islands around the world reveals their unique characteristics, surprising features, and remarkable geographical distinctions.
1. World’s Largest Island
Greenland holds the title of the world’s largest island, covering an area of approximately 836,330 square miles (2,166,086 square kilometers). Notably, while Antarctica is larger, it’s classified as a continent, not an island.
2. Smallest Inhabited Island
Just Room Enough Island, part of the Thousand Islands archipelago between Canada and the United States, is the world’s smallest inhabited island. It’s only big enough to fit a single house with a small tree.
3. Most Populated Island
Java, Indonesia, holds the record for the most populated island globally, with over 140 million inhabitants. This makes it more populous than most countries in the world.
4. Island Nation with Most Islands
Sweden claims to have the most islands of any country, with an estimated 267,570 islands. However, only about 984 of them are inhabited.
5. Disappearing Islands
The Pacific nation of Kiribati is gradually disappearing due to rising sea levels. It’s estimated that these islands could become uninhabitable by 2050 due to climate change.
6. Newest Island
Volcanic activity in the Pacific Ocean regularly creates new islands. The newest named island emerged near Tonga in 2015 following a volcanic eruption, though many such islands are temporary.
7. Moving Island
Surtsey Island near Iceland, formed by volcanic activity in 1963, is one of the world’s newest permanent islands. It’s been moving eastward by approximately 9.9 feet (3 meters) per year due to plate tectonics.
8. Most Remote Inhabited Island
Tristan da Cunha in the South Atlantic Ocean is the most remote inhabited island, lying 1,514 miles (2,437 kilometers) from the nearest mainland (South Africa).
9. Island Shared by Most Countries
Borneo is shared by three countries: Malaysia, Indonesia, and Brunei, making it the island divided among the most sovereign nations.
10. Highest Island
New Guinea boasts the highest island peak, Puncak Jaya (Carstensz Pyramid), reaching 16,024 feet (4,884 meters) above sea level.
11. Artificial Island Record
Palm Jumeirah in Dubai is the world’s largest artificial island, covering approximately 560 hectares and created entirely through land reclamation.
12. Island Within an Island
Isle Royale in Lake Superior contains several lakes, and within one of these lakes is Ryan Island, making it the largest island in the largest lake on the largest island in the largest freshwater lake in the world.

14. Oldest Island
Madagascar separated from mainland Africa approximately 160 million years ago, making it one of the oldest islands in existence. This long isolation has resulted in unique flora and fauna.
15. Seasonal Island
Zalzala Koh, off Pakistan’s coast, appeared after an earthquake in 2013 but disappeared completely by 2016, demonstrating how some islands can be temporary geographical features.
16. Split Personality Island
Saint Martin/Sint Maarten is the smallest inhabited island divided between two nations (France and the Netherlands), covering just 37 square miles (96 square kilometers).
17. Island with Two Time Zones
Big Diomede and Little Diomede islands, separated by just 2.4 miles (3.8 kilometers), lie on different sides of the International Date Line, creating a 24-hour time difference between them.
18. Underwater Island
The Bimini Road in the Bahamas is believed by some to be the remnants of an ancient submerged island, though scientific evidence suggests it’s a natural formation.
These fascinating island facts demonstrate the incredible diversity and unique characteristics of Earth’s islands. From the largest to the smallest, the most populated to the most remote, islands continue to intrigue geographers, scientists, and curious minds worldwide. They serve as remarkable examples of our planet’s dynamic geological processes and the complex relationship between land, sea, and human civilization.
