In this article, we will take a look at the 30 most densely populated islands in the world. For more islands, head on over to the 5 Most Densely Populated Islands in the World.

Population density is a key metric that indicates how densely populated a specific area is, representing the number of people per unit of land area. According to Our World in Data, the global average population density in 2023 stands at 62 people per km2, with considerable variation across different regions. Islands, in particular, often exhibit higher population densities compared to their geographic sizes. Notable islands with high populations include Migingo Island in Lake Victoria, East Africa, which is also the most densely populated island in Africa. Furthermore, Santa Cruz del Islote, a tiny island on the Caribbean coast of Colombia, is reported by the BBC to house five hundred people in 115 houses, occupying an area the size of a soccer field. This makes it the world's most densely populated island. Meanwhile, Monaco is the most densely populated country, with a population density of 18,343 people per km2.

Several islands are remotely located, away from traditional trading routes, and are increasingly vulnerable to climate change. Many also happen to have a high degree of dependency on tourism for their economic growth. According to Forbes, six of the top ten countries dependent on tourism are island states. With tourism generating revenues of over $1 trillion globally, it represents a continually growing industry. In 2019, 27 out of 44 countries dependent on travel and tourism for over 15% of their total share of employment were islands. While tourism offers economic benefits, it also presents adverse implications for already fragile island ecosystems and influences the social structure of these islands. Both the World Tourism Organization (WTO) and the United Nations (UN) recognize these concerns as significant issues. Consequently, many islands are collaborating with the WTO to develop sustainable ecotourism as an alternative to traditional tourism models.

According to the World Travel & Tourism Council (WTTC), the Travel and Tourism sector made up 7.6% of global GDP in 2022. This marked a 22% increase from the previous year, though it remained below pre-pandemic levels. Three out of the ten island nations most affected by a decline in tourism are Fiji (13%), Mauritius (10%), and Jamaica (9%). Some of the notable companies capitalizing on the recovery of travel post the pandemic include Airbnb (NASDAQ:ABNB), Expedia Group, Inc. (NASDAQ:EXPE), and Booking Holdings Inc. (NASDAQ:BKNG).

Here’s what RiverPark Advisors said about Booking Holdings Inc. (NASDAQ:BKNG) in its Q3 2023 investor letter:

“Booking Holdings Inc. (NASDAQ:BKNG): BKNG was a top contributor in the quarter following better than expected bookings, revenue and profit margins in the company’s 2Q driven by strong summer travel demand. BKNG reported $40 billion of bookings, $5.5 billion of revenue, and 23% EBITDA margins, which were $1.5 billion, $300m, and two percentage points ahead of expectations, respectively. In addition to strong summer demand, management pointed to continued strength in leisure travel (they raised travel booking guidance for the remainder of the year), building momentum in its alternative accommodation business and improvement in marketing efficiency.

Booking is the world’s leader in online travel, operating in 200 countries with brands including Booking.com, priceline.com, agoda.com, Kayak, Rentalcars.com and OpenTable. The company has been a dominant on-line travel agency for more than a decade with a high-margin business model that requires limited capital expenditures, typically less than 3% of revenue, producing $6.2 billion of free cash flow for 2022 and $7.2 billion expected for 2024. The company has used its free cash flow for episodic acquisitions as well as to return cash to shareholders. BKNG is well positioned in travel as the largest player in online lodging bookings and the second largest player in alternative accommodations.”

Our Methodology

To shortlist the 30 most densely populated islands in the world, we consulted the Visual Capitalists’ list of the 100 biggest islands in the world. The data visualization, crafted by mapmaker David Garcia, systematically ranks the 100 largest islands globally by their respective sizes. We used the latest population estimates to rank the islands in ascending order of their population densities. It is important to note that the list excludes islands with minimal land areas, such as Santa Cruz del Islote, as obtaining the latest accurate data for such islands is challenging.
