More than 70% of the Earth’s surface is covered with water, and between these waters lie hundreds of thousands of islands. By definition, an island is a land mass surrounded by a body of water. 

Although continents fall under this definition as well, they are still not considered islands due to their enormity. To put into perspective, Australia, the smallest continent with a land area of almost 7.7 million square kilometers, is more than three times the size of the largest island in the world — Greenland — which has a landmass of over 2.1 million square kilometers. 

Officially, there are over 600,000 islands in the world, but this data is neither 100% accurate nor set in stone.

Officially, there are over 600,000 islands in the world, but this data is neither 100% accurate nor set in stone. Partly, this is due to the sheer number of Islands in the world, and the constant emergence of new islands due to natural processes like volcanic eruptions or through movement of tectonic plates. Furthermore, while many new islands appear over time, the old ones disappear as well through erosion and subsidence and natural disasters like earthquakes and tsunamis.

Apart from size, climate, and the kinds of organisms that inhabit them, these islands vary greatly in geographic features as well. Some islands, like the Aleutian Islands in the US state of Alaska, are cold and covered with ice throughout the year, while others, like Tahiti, are warm and on tropical waters. Regardless of climatic features, islands are generally known as the magnets for the tourism industry. For instance, Taiwan, an island country in East Asia, ranked 34th on the list of most visited countries in the world in 2024. 

Islands and Tourism Industry

Out of the top 10 countries that heavily rely on tourism, six are island nations; island-rich countries leverage their natural assets to generate economic output through tourism. Small island nations are especially reliant on this industry because they have small economies and their excellent island beaches bring economic activity to the country. As evident by the number of countries with well-developed seaside facilities, beaches are one of the favorite spots for tourists. 

Being an island country, Maldives is an ideal example of this. It is an island country with a population of 550,000 people dispersed across 185 islands, and it relies heavily on tourism to sustain its economy. In fact, tourism accounted for one-third of the country’s economy in the first half of 2023. Moreover, its overall revenue from tourism accounted for $4.2 billion in 2022, which equaled 68% of the GDP of the country.

Island-rich countries like Maldives have a great travel and tourism market, attracting key players like Intercontinental Hotels Group Plc (NYSE:IHG), Marriott International Inc. (NYSE:MAR), and Hilton Worldwide Holdings Inc (NYSE:HLT) in the tourism and hospitality industry. 

Intercontinental Hotels Group Plc (NYSE:IHG) is one of the leading companies in the hospitality industry. Back in September 2019, Intercontinental Hotels Group Plc (NYSE:IHG) made its debut in Maldives by opening a luxurious resort –  InterContinental® Maldives Maamunagau Resort. The resort features 81 luxurious rooms available in three different categories and private pools with each room.

Meanwhile, Marriott International Inc. (NYSE:MAR) is a global hotel and resort company with nearly 8,700 properties across 139 countries and territories. Last year, in November 2023, Marriott Maldives Business Council, an affiliate of Marriott International Inc. (NYSE:MAR), partnered with USAID to expand economic opportunities for residents across the islands in Maldives.  

On the other hand, Hilton Worldwide Holdings Inc (NYSE:HLT) also contributes significantly to Maldives’s hospitality and tourism industry. The company has a broad portfolio of managing and franchising hotels, resorts, and timeshare properties. Hilton Worldwide Holdings Inc (NYSE:HLT) made one more addition to its portfolio in July 2022, with the opening of Hilton Maldives Amingiri Resort & Spa, making it the fourth resort managed by Hilton Worldwide Holdings Inc (NYSE:HLT) in Maldives.
