Countries Most Dependent on Tourism: Data Ranked

For most countries, tourism is a welcome supplement to a diversified economy. For the nations at the top of this ranking, it is the economy. When visitors fill Aruba's beaches, the island prospers. When a pandemic shuts international travel, the same island's output drops by almost a quarter in a single year.

This article ranks economies by how much of their income comes from visitors, using World Bank figures from 2019, the last year before COVID-19 distorted everything. It also explains why small islands dominate the top of the list, what the 2020 shock did to each country, and how to read dependency figures without being misled by them.

Key takeaways

• On the World Bank's figures, international tourism receipts equaled about 63% of Aruba's GDP and about 55% of the Maldives' GDP in 2019, far above any other economy in the sample
• Small island economies fill the top of the ranking, but large economies such as Thailand, Greece, and Portugal also earned more than 10% of GDP from international visitors
• In 2020, the Maldives' real GDP shrank 32.9%, Aruba's 23.9%, and the Bahamas' 20.1%, while less dependent economies fell by single digits
• Different organizations measure "tourism's share of the economy" differently, so a country can look much more or less dependent depending on the source
• Globally, the World Travel and Tourism Council (WTTC) estimates tourism's total contribution at US$11.6 trillion, or 9.8% of global GDP, in 2025

Three ways to measure dependency

"Dependent on tourism" sounds like a single number, but there are at least three measures in common use, and they give different answers.

The first is international tourism receipts as a share of GDP. This counts only money spent by foreign visitors and compares it to the size of the economy. It is the measure used in this ranking because the World Bank publishes both numbers for most countries, so anyone can reproduce the calculation.

The second is tourism's share of exports. Spending by foreign visitors counts as an export of services, since the money comes from abroad. The World Bank reports this as a percentage of total exports. For 2020, even in a collapsed travel year, it was 74.6% for Aruba, 78.9% for the Maldives, 59.6% for the Bahamas, and 50.4% for Vanuatu (World Bank, ST.INT.RCPT.XP.ZS).

The third is the total contribution published by the WTTC, which adds direct spending, supply-chain purchases, and the spending of people whose wages come from tourism. This yields larger figures than the first two. The World Bank's Maldives overview, for example, says tourism represents about 21% of GDP, far below the 55% that 2019 receipts imply here; the page does not explain the gap, but it shows how much the answer depends on the definition and the year (World Bank: Maldives overview).

None of these is wrong. They answer different questions: how much foreign currency arrives, how much of the whole economy touches visitors, and how much would vanish if visitors stopped coming. A fair reading of any ranking, including this one, requires knowing which question it answers.

The ranking: tourism receipts as a share of GDP, 2019

The table below divides each country's international tourism receipts (current US dollars) by its GDP (current US dollars) for 2019. Real GDP growth for 2020 and international arrivals for 2019 are included to show how exposed each economy proved to be. Countries where the World Bank has no published receipts series are listed separately below the table.

Rank	Country	Receipts as % of GDP, 2019	Real GDP growth, 2020	International arrivals, 2019
1	Aruba	63.0%	-23.9%	1,951,000
2	Maldives	55.4%	-32.9%	1,703,000
3	Seychelles	33.1%	-11.7%	428,000
4	Bahamas	31.3%	-20.1%	7,250,000
5	Vanuatu	27.8%	-5.7%	256,000
6	Fiji	25.2%	-17.2%	969,000
7	Montenegro	23.3%	-15.0%	2,510,000
8	Croatia	19.5%	-8.3%	60,021,000
9	Cambodia	14.5%	-3.6%	6,611,000
10	Thailand	11.8%	-6.1%	39,916,000
11	Greece	11.1%	-9.2%	34,005,000
12	Portugal	10.2%	-8.2%	17,283,000

See Sources. Arrival counting rules differ by country; Croatia's figure in particular appears to include visitors who do not stay overnight.

For the Bahamas, receipts were US$4.15 billion against GDP of US$13.28 billion. For Aruba, US$2.11 billion against GDP of US$3.35 billion. Those two ratios are the kind of arithmetic that shows up in a household budget: if more than half of an economy's income arrives in a single envelope, the arrival of that envelope becomes the main fact of economic life.

Countries with no published receipts series

The World Bank does not publish a 2019 international tourism receipts figure for several economies that are widely described as tourism-dependent. Rather than guess, the table below shows what the same sources do report for them.

Country	Real GDP growth, 2020	International arrivals, 2019	Population, 2023
Barbados	-17.4%	966,000	282,336
Jamaica	-8.3%	4,233,000	2,839,786
Dominican Republic	-7.9%	7,550,000	11,331,265
Iceland	-6.6%	2,202,000	385,663
Malta	-3.5%	3,519,000	552,747
Palau	-6.0%	94,000	17,727
New Zealand	-0.2%	3,888,000	5,200,000
British Virgin Islands	not published	302,400	38,985

The World Bank has no matching series for these places, so no share-of-GDP figure is given for them. Readers who need the WTTC's total-contribution numbers for a specific country can find them in its country reports, which sit behind a product page.

Why small islands are the most exposed

Look at the top of the table and a pattern jumps out: Aruba, the Maldives, Seychelles, the Bahamas, Vanuatu, and Fiji are all small islands or island chains. The reason is not that islands are naturally better at tourism. It is that they have fewer alternatives.

A large country can lose its tourists and still have farms, factories, and a financial sector. An island with 100,000 people has little room for those. It cannot grow most of its food, it lacks the population to support domestic manufacturing at scale, and it faces high shipping costs to export anything heavy. Tourism, by contrast, exports a service that requires no shipping: the customer travels to the product.

The ratio of visitors to residents

One simple way to see the imbalance is to compare annual arrivals to population. The figures below mix 2019 arrivals with 2023 population, so they are approximations, but the order of magnitude is the point.

Country	Arrivals 2019	Population 2023	Approximate arrivals per resident
Aruba	1,951,000	107,359	18
Bahamas	7,250,000	399,440	18
Malta	3,519,000	552,747	6
Iceland	2,202,000	385,663	6
Palau	94,000	17,727	5
Montenegro	2,510,000	623,529	4
Seychelles	428,000	119,773	4
Barbados	966,000	282,336	3
Maldives	1,703,000	525,994	3
Fiji	969,000	924,145	1

Source: World Bank indicators ST.INT.ARVL and SP.POP.TOTL; ratios rounded by SciHub101. Some countries count cruise passengers and day visitors as arrivals and others do not.

Aruba and the Bahamas see about 18 arrivals per resident per year, but the high ratio is only one part of the story. The Maldives has a lower ratio yet a higher dependency on a per-visitor basis, because its resorts are built to earn a great deal from each guest. For a ranking built on visitor numbers rather than money, see our article on countries with the most tourists per capita.

How much each visitor is worth

Arrivals alone do not tell you how much money a destination earns. Dividing 2019 receipts by 2019 arrivals gives a rough figure for revenue per arrival, which varies by a factor of nine across the countries with data.

Country	Receipts, 2019 (US$)	Arrivals, 2019	Approximate receipts per arrival
Maldives	3.17 billion	1,703,000	$1,862
Thailand	64.37 billion	39,916,000	$1,613
Seychelles	618 million	428,000	$1,444
Portugal	24.59 billion	17,283,000	$1,423
Fiji	1.35 billion	969,000	$1,388
Vanuatu	295 million	256,000	$1,152
Aruba	2.11 billion	1,951,000	$1,081
Cambodia	5.31 billion	6,611,000	$804
Greece	23.00 billion	34,005,000	$676
Bahamas	4.15 billion	7,250,000	$572
Montenegro	1.28 billion	2,510,000	$508
Croatia	11.97 billion	60,021,000	$199

Read this table with care, because arrival definitions differ. A country that counts cruise passengers or day visitors as arrivals will show a low revenue per arrival, since those visitors spend little. That probably explains the low figures for the Bahamas and Croatia. Stays also differ in length, and long-haul visitors spend more per trip than people who drive across a border.

Even so, the table makes a point about strategy. The Maldives earned roughly $1,860 for each arrival, nearly twice Aruba's $1,081, which is how it reached a dependency of 55% of GDP with fewer visitors than Aruba. A high-value, low-volume model can carry as much economic weight as mass tourism, but it concentrates the risk in fewer, wealthier customers. If a few source markets weaken, the effect on revenue is outsized.

Aruba: the most tourism-dependent economy in the sample

Aruba's tourism receipts equaled about 63% of GDP in 2019, the highest of any country the World Bank reports on. The island had about 1.95 million international arrivals that year, against a population of roughly 107,000 in 2023. In 2020, its real GDP fell 23.9%.

The structure of the economy follows from those numbers. Hotels, restaurants, retail, construction, and transport are all oriented around visitors, and most of the jobs that are not directly in hospitality exist to serve people who work in it. When arrivals stop, the effects reach the plumber, the grocer, and the bus driver within weeks.

Concentration of source markets adds a second layer of exposure. An island that depends on visitors from a single large country is tied to that country's business cycle as well as to global travel conditions. Aruba is not unique in this, but the effect is magnified when one economy supplies most of the guests. The 2020 shock was global, so diversification of markets could not have shielded it, but in an ordinary recession the benefit of having many source markets is real.

For a sense of how Aruba's visitor flow compares with the world's busiest destinations, see Countries with the Most Tourist Arrivals. Large destinations rank by volume; small ones rank by intensity, and the two lists barely overlap.

The Maldives: a resort model built on high-value guests

The Maldives ranks second at about 55% of GDP in 2019, with about 1.70 million arrivals and a 2020 contraction of 32.9%, the worst in the sample. Tourism began there in 1972 with two resorts, the first of them Kurumba Island Resort, and the country later became known for a model in which one island is one resort: a single hotel occupies the whole island (Wikipedia: Tourism in the Maldives).

The arrangement concentrates revenue in high-priced stays and keeps guest and resident life apart, but it also concentrates risk. The World Bank reported that Maldives public and publicly guaranteed debt reached US$9.5 billion, or 126.9% of GDP, in 2025, with official reserves of US$774.5 million, about 1.8 months of imports (World Bank: Maldives overview). A country with thin reserves and high debt has little cushion when the main source of foreign currency stops.

Arrivals fell from about 1.70 million in 2019 to 555,494 in 2020, according to a by-nationality table on Wikipedia that draws on national statistics. The two tables come from different sources, so the figures are not perfectly comparable, but the scale of the drop is not in doubt: a country that loses roughly two-thirds of its visitors in a year will see a deep economic shock whatever the exact count.

Reefs, beaches, and the asset base

Tourism in the Maldives rests on a natural asset base of reefs, clear water, and beaches. Healthy reefs also help protect low-lying islands from wave erosion, and they support the marine life that draws divers. Damage to reefs therefore threatens both the product and the physical land. The biology of why reefs bleach and recover is covered in Coral Reefs Explained. We do not quote specific bleaching percentages here because estimates vary by atoll and survey method.

The Caribbean and the Pacific: small economies, similar patterns

The Bahamas earned about 31% of GDP from visitor receipts in 2019 and contracted 20.1% in 2020. Barbados, where the World Bank publishes no receipts series, fell 17.4%. Fiji, with receipts equal to about 25% of GDP, fell 17.2%. Vanuatu, at about 28%, fell only 5.7%, a gap that shows how much policy and structure matter alongside dependency.

Possible reasons include a larger non-tourism economy, differences in how long borders stayed shut, and the way output is measured. GDP growth figures for small economies are revised often and can be uncertain, so a gap of a few percentage points should not be over-interpreted.

Why the 2020 collapse did not match dependency exactly

If dependency were the only driver, the ranking and the 2020 column would line up. They do not, and that is instructive:

• Cambodia was only 14.5% dependent by this measure and fell 3.6%.
• New Zealand has no published receipts series, yet its real GDP fell just 0.2% in 2020.
• Montenegro fell 15.0%, nearly twice Croatia's 8.3%, even though its dependency (23.3%) was only a few points higher than Croatia's (19.5%).
• Jamaica fell 8.3%, less than half of Barbados at 17.4%, though both are widely described as heavily tourism-reliant.

The data cannot say why. Plausible factors include how long borders stayed closed, how much domestic demand replaced foreign demand, what government support was available, and how the rest of the economy fared. Dependency sets the size of the exposure; policy and timing decide how much of it is realized.

Europe's tourism economies

Europe has few island microstates in this ranking, but it does have countries where tourism punches above its weight. Montenegro earned about 23% of GDP from visitors in 2019, and Croatia about 19.5%. Both are Adriatic coastal economies in which a short, intense summer season supplies a large share of annual income. Greece (11.1%) and Portugal (10.2%) are far larger economies and stand lower on the list, though in absolute terms their receipts of US$23.0 billion and US$24.6 billion in 2019 are far larger than those of Seychelles or Aruba.

That distinction between share and size matters. A country can be a major tourism earner without being tourism-dependent. Greece receives millions more visitors than the Maldives, but because its economy is much larger and more varied, tourism is a smaller fraction of what it produces. The World Bank's receipts figure for Thailand, US$64.4 billion in 2019, is the largest in this table in absolute terms, yet it represents under 12% of GDP.

Croatia's GDP fell 8.3% in 2020, Montenegro's 15.0%, Greece's 9.2%, and Portugal's 8.2%, all in the range one would expect for economies that depend on summer travel but have other sectors to fall back on.

Iceland: a rapid rise and a sudden stall

Iceland is not in the receipts table because the World Bank has no 2019 series for it, but its recent history is a textbook case of how fast a tourism boom can arrive. International arrivals reached about 2.2 million in 2019, in a country of roughly 386,000 people in 2023.

A major piece of that growth rested on a single airline. WOW air ceased operations on March 28, 2019, and the airline had previously carried more than a quarter of all visitors to Iceland (Wikipedia: WOW air). The shock that followed, and then the pandemic, in which Iceland's real GDP fell 6.6% in 2020, show how a small economy can be affected by the decisions of one carrier as well as by global events. The social effects of fast growth, including pressure on housing and on popular natural sites, are a common feature of tourism booms that arrive faster than infrastructure.

The global picture: how big is tourism overall?

At the world level, tourism is large but not dominant. The WTTC estimates that travel and tourism contributed US$11.6 trillion to global GDP in 2025, equal to 9.8% of the total, and supported 366 million jobs, about one in nine jobs worldwide (WTTC: Economic Impact Research). That is the broad total-contribution measure, so it is larger than receipts-based figures.

On the demand side, UN Tourism reported about 1.3 billion international arrivals in 2023, equal to 88% of pre-pandemic levels, and international tourism receipts of US$1.4 trillion, about 93% of 2019 (UN Tourism). Its initial estimates pointed to 2024 arrivals about 2% above 2019, which would mean full recovery. Our readers should treat the 2024 figure as an early estimate unless they check the current UN Tourism release.

Against that backdrop, a country earning 55% to 63% of GDP from visitors is not slightly above the world average. It is several times as dependent, though the two figures use different definitions and cannot be compared exactly. Even allowing for that, the gap explains why small tourism economies are usually treated as a separate category of vulnerability.

Can tourism-dependent economies diversify?

Diversification is the standard prescription and the hardest one to fill. A few approaches have been tried, each with limits.

Financial services. Some small jurisdictions have built offshore financial sectors alongside tourism. These depend on regulatory arrangements that can change under international pressure, so they replace one external dependency with another.

Remote-worker programs. Several island governments have created long-stay visas to attract people who can work from anywhere. The numbers are small relative to a mass tourism base, but the visitors stay longer and spend through the year rather than in peak season.

Local linkages. Tourism leaks money when hotels import food, furniture, and staff. Economists call this leakage. Raising the share of goods bought locally, from fish to produce to construction materials, can lift the income that stays in the country without needing more guests. How much leaks varies by country and by hotel type, and we do not give a figure here because published estimates are inconsistent.

Other exports. Renewable energy, aquaculture, and digital services are sometimes proposed, but they start from a small base. The economics of attracting investment are covered in Countries Attracting the Most Foreign Direct Investment.

The common thread is that diversification takes years and scale, and small islands have neither in abundance. Resilience in practice is often less about replacing tourism than about cushioning against its swings: building reserves, managing debt, and insuring against hurricanes and travel shocks.

Currency, debt, and the cushion

Tourism earnings arrive in foreign currency, which supports an island's ability to import food and fuel. When the earnings stop, reserves drain. The relationship between reserves, exchange rates, and import capacity is explained in Why Currency Exchange Rates Change. Debt compounds the problem, since interest payments are due whether or not visitors arrive; for a broader view of how sovereign borrowing is assessed, see Countries With the Highest National Debt.

What the rankings can and cannot tell you

A few cautions apply to any list like this one, including ours.

Year matters. The 2019 numbers are used because they reflect a normal year. In 2020 and 2021, receipts collapsed and GDP shrank, so ratios computed then would not measure dependency in any ordinary sense. Recovery since has been uneven, and current ratios may differ.

Currency and GDP revisions. Small economies have volatile GDP and large revisions. A ratio calculated in current US dollars can move because of exchange rates or price changes alone.

Definitions of "visitor." Countries differ in whether they count cruise passengers, day-trippers, and returning residents. That is why Croatia's 60 million arrivals look implausible for a country of 3.9 million people: the figure appears to include non-overnight visitors. Use arrivals for rough scale, not for precise comparisons.

A high number is not automatically a problem. Tourism creates jobs and foreign exchange where alternatives are scarce. The risk lies in concentration, not in tourism as such. To understand how GDP itself is measured, and why shares of it behave as they do, see What Is GDP and Why It Matters.

Attractions explain demand, not dependency. Heritage sites and natural wonders draw visitors, but dependency depends on how large the rest of the economy is. For a different lens on what draws travelers, see our list of countries with the most UNESCO World Heritage Sites.

Frequently asked questions

Q: Which country is the most dependent on tourism? A: By the measure used here, international tourism receipts relative to GDP in 2019, Aruba comes first at about 63%, followed by the Maldives at about 55%. Both figures are calculated from World Bank data, and other organizations using broader definitions would give different numbers.

Q: Is tourism dependency always negative? A: No. Tourism supplies jobs and foreign currency where alternatives are limited. The risk is concentration: when one sector dominates, a shock to travel, such as a pandemic, a hurricane, or a geopolitical event, causes outsized damage with few other sectors to absorb it.

Q: How did COVID-19 affect tourism-dependent economies? A: In 2020, the Maldives' real GDP fell 32.9%, Aruba's 23.9%, the Bahamas' 20.1%, Barbados' 17.4%, and Fiji's 17.2%, according to World Bank data. Not every dependent economy fell as far; Vanuatu's fell 5.7%, showing that policy and economic structure also matter.

Q: What share of global GDP is tourism? A: The WTTC estimates that travel and tourism contributed US$11.6 trillion, or 9.8% of global GDP, in 2025, and supported 366 million jobs. That is the total-contribution measure, which includes indirect and induced effects, so it exceeds figures based only on visitor spending.

Q: Can small island nations realistically diversify away from tourism? A: Only slowly and partly. Financial services, long-stay visa programs, local supply chains, and small-scale export industries all help at the margin, but none matches the scale of tourism revenue in the most exposed economies. Reserves, debt management, and insurance often matter as much as diversification.

Q: Why does this ranking differ from other lists I have seen? A: Lists differ because they use different measures: receipts as a share of GDP, share of exports, or total contribution to GDP, and they use different years. This ranking uses World Bank receipts and GDP for 2019 so that every figure can be checked.

The bottom line

The countries most dependent on tourism are small, mostly island economies where beaches, reefs, and climate produce visitor income that dwarfs any alternative. Aruba and the Maldives stand apart, with receipts above half of GDP in 2019, and the 2020 shock hit them hardest. But the data also show that dependency is not destiny: policy, timing, and structure shaped how much each country lost. The most useful way to read a tourism-dependence ranking is as a map of concentrated risk, one that points to the importance of reserves, local supply chains, and a willingness to plan for the next interruption in travel.
