About Island Countries

An Island is a piece of land that is surrounded by water and is smaller than a continent. Countries located on Islands are called Island Countries. There are 50 Island Countries in the world. Australia is not an Island county because it is a continent, despite the fact that it was once thought to as an Island due to its lack of land borders. The largest Island country on Earth, according to most people, is Greenland, which is included in the list of Island countries. Indonesia is the largest Island nation in the world in terms of both area (1,904,569 km2) and number of islands (17,504 islands). With a population of more than 270 million, it is also the Island country with the largest population worldwide.

Many of the Island countries are enormous and have significant population, some of them are small and poorly populated. There are Island countries in every region of the globe and in every ocean. There are 18 Island countries in the Atlantic Ocean. However, only three of these nations are actually located in the Atlantic Ocean. They are the United Kingdom, Ireland, and Iceland. The Caribbean Sea and the Mediterranean Sea are home to the other island countries. Caribbean has two island countries and Mediterranean has two Island nations. The United Kingdom is the largest and most populous island country in the Atlantic Ocean. It is made up of the Island of Great Britain and the northern region of Ireland, known as Northern Ireland.

Caribbean consists of 13 Island countries that are quite small in comparison to those in the main part of the Atlantic Ocean. Cuba is the largest of the Caribbean island countries, with a land area of 110,860 square kilometers. Haiti is the second largest island country in the Caribbean. Only four Caribbean Island nations—Cuba, Haiti, the Dominican Republic, and Trinidad & Tobago—have populations in the millions. Malta and Cyprus are two Island nations that are located in the Mediterranean Sea. Though from a geographical aspect, Cyprus is technically a part of Asia both are currently EU members. Cyprus has a population of about 1.2 million, compared to Malta's population of slightly under 443,000.

There are 6 Island countries in the Indian Ocean. They are Seychelles, Comoros, Mauritius, Madagascar, Sri Lanka, and the Maldives. The largest and most populous island country in the Indian Ocean is Madagascar. The Seychelles is the Indian Ocean's smallest and least populated country. Madagascar and Sri Lanka are large Island countries, whereas Mauritius is a small Island nation.

There are 23 island countries in the Pacific Ocean. The largest Island countries of Pacific Ocean are Japan, the Philippines, Indonesia, Australia and New Zealand. Japan is the only Island country in East Asia. It has a population of about 126 million people, making it the world's second most populous Island country after Indonesia. Southeast Asia is home to five Island nations. Indonesia, the most populated Island country in the world with a population of about 276 million, is the biggest and most populous. The Philippines, which has 7,640 islands, is the other major Island nation in Southeast Asia. East Timor, Brunei, and Singapore are Southeast Asia's other, smaller Island nations. Despite its diminutive size, Singapore is one of the so-called Asian Tiger economies and a powerhouse in terms of the economy.
