1. Brunei
Brunei is a sovereign nation located on the northern coast of Borneo Island in Southeast Asia. Except for its coastline along the South China Sea, this country is entirely surrounded by the Malaysian state of Sarawak. The Limbang district of Sarawak divides Brunei into two parts. Brunei is the only sovereign nation entirely located on Borneo, with the remaining parts of the island controlled by Malaysia and Indonesia.
The official history of Brunei suggests that its origins date back to the 7th century, when it was a vassal state called P'o-li under the Srivijaya Empire based in Sumatra. Later, it became a tributary of the Majapahit Empire, headquartered on Java. Brunei became an Islamic kingdom in the 14th century under Sultan Muhammad Shah, who converted to Islam.
At its peak, the Brunei Kingdom, under Sultan Bolkiah (reigned 1485–1528), controlled northern Borneo, including modern-day Sarawak and Sabah, as well as the Sulu Archipelago off northeastern Borneo, Seludong (now Manila), and islands off northwestern Borneo. The Spanish expedition led by Magellan visited this maritime nation in 1521, and Brunei fought against Spain in the Castille War of 1578.
Brunei, though small, is one of the wealthiest nations in the world, thanks to contributions from local and international entrepreneurs. With the government's policies and high social welfare, Brunei's GDP per capita stands at an impressive $83,780 USD.
This high GDP per capita is primarily driven by the export of crude oil and natural gas. Like other prominent oil-exporting countries, Brunei's government has made significant strides in diversifying its economy.


2. Ireland
Ireland is a sovereign nation located in the northwestern part of Europe, occupying roughly five-sixths of the island of Ireland. Its capital and largest city, Dublin, is situated on the eastern side of the island, with around one-third of the country's population of 4.75 million residing in the metropolitan area.
The Republic of Ireland shares its only land border with Northern Ireland, which is part of the United Kingdom. It is surrounded by the Atlantic Ocean, with the Celtic Sea to the south, the Saint George's Channel to the southeast, and the Irish Sea to the east. Ireland operates as a unitary republic with a parliamentary system.
The Irish Free State was formed in 1922 as a result of the Anglo-Irish Treaty. Ireland enjoyed self-governing status until it adopted a new constitution in 1937, which officially named the country "Ireland" and established a republic, with an elected president as the head of state.
Ireland was formally declared a republic in 1949. It became a member of the United Nations in 1955 and joined the European Economic Community (EEC) in 1973. Though it did not have official relations with Northern Ireland for most of the 20th century, the governments of the UK and Ireland worked through the 1980s and 1990s to resolve the conflict in Northern Ireland.
Since the signing of the Good Friday Agreement in 1998, Ireland and Northern Ireland's governments have collaborated on a range of policy areas within the North-South Ministerial Council framework.
Ireland boasts an impressive GDP per capita of $82,440. Key sectors driving Ireland's economy include textiles, mining, and food production, which are significant contributors to many global economies.


3. Norway
Norway, formally known as the Kingdom of Norway, is a Nordic country situated in the far northwestern part of Europe. Its territory spans the western and northern parts of the Scandinavian Peninsula and includes the Arctic islands of Jan Mayen and the Svalbard archipelago. Additionally, Norway has territorial claims over Peter I Island and Queen Maud Land in Antarctica, and also governs the Bouvet Island located in the Subantarctic region.

It also borders Finland and Russia in the northeast. To the south, the Skagerrak Strait connects Norway to Denmark, and the country boasts a long coastline along the North Atlantic Ocean and the Barents Sea.
Norway's climate is moderated by the surrounding oceans, making it much milder than other northern countries at similar latitudes. Even in the polar night, temperatures generally remain above freezing. The oceanic influence also brings heavy rainfall and significant snowfall to many regions.
With a GDP per capita of $76,740, Norway's well-developed economy supports nearly 5 million people. Known for its global presence in fishing, natural resources, and oil exploration, Norway is the 8th largest exporter of crude oil, 9th in refined oil, and ranks 3rd in natural gas exports worldwide.


4. United Arab Emirates
The United Arab Emirates (UAE) is a country in Western Asia, located on the southeastern edge of the Arabian Peninsula along the Persian Gulf. It borders Saudi Arabia to the south and east, and has maritime borders with Qatar to the west and Iran to the north.

5. Kuwait
Kuwait is a country located in Western Asia, situated at the northern edge of the Arabian Peninsula and at the head of the Persian Gulf. It shares borders with Iraq to the west and Saudi Arabia to the south. As of 2016, Kuwait's population is around 4.2 million, with 1.3 million Kuwaiti nationals and 2.9 million expatriates.
Oil was discovered in Kuwait in 1938, sparking significant modernization from 1946 to 1982. The country faced political instability and an economic crisis in the 1980s after a stock market collapse. In 1990, Iraq invaded Kuwait, but the occupation was ended in 1991 through a military intervention by coalition forces. Afterward, efforts to restore the economy and rebuild the nation’s infrastructure were carried out on a large scale.
Kuwait operates as a constitutional monarchy with a semi-democratic system. It is considered a high-income nation due to its vast oil reserves, ranking as the sixth-largest oil producer in the world. The Kuwaiti dinar is the highest-valued currency globally. The constitution of Kuwait, enacted in 1962, makes it one of the most democratic nations in the region. Kuwait is also home to the largest opera house in the Middle East, and it is often referred to as the 'Hollywood of the Gulf' due to the popularity of its television series and theater productions.
Kuwait has a relatively open economy, with a remarkable GDP per capita of $67,970. The country holds nearly 10% of the world’s oil reserves, and oil and gas contribute nearly 50% of its GDP and around 95% of its export revenues. In recent years, Kuwait has been actively diversifying its economy, especially with positive developments in the financial sector.


6. Switzerland
Switzerland, officially known as the Swiss Confederation, is a federal republic located in Europe. This country is composed of 26 cantons, with the city of Bern serving as the seat of the federal government.
Switzerland lies in Western and Central Europe, bordered by Italy to the south, France to the west, Germany to the north, and Austria and Liechtenstein to the east. It is a landlocked nation, covering an area of 41,285 km², with its geography dominated by the Alps, the Swiss Plateau, and the Jura Mountains. While the Alps cover much of the territory, around 8 million Swiss citizens primarily reside in the Plateau. The country's major cities, including the global financial centers of Zurich and Geneva, are also located in this region.
The origins of Switzerland trace back to the Medieval period, marked by a series of military victories against Austria and Burgundy. The country was officially recognized as independent from the Holy Roman Empire through the Peace of Westphalia in 1648. Switzerland has maintained a stance of military neutrality since the Reformation era and has not been involved in international wars since 1815, refraining from joining the United Nations until 2002. Nevertheless, Switzerland pursues an active foreign policy and is often involved in global peace-building efforts.
Switzerland's GDP per capita stands at 65,741 USD. The Swiss banking sector and financial institutions play a dominant role in the country's economy. Notably, many of the wealthiest individuals and top global companies store their accounts in Swiss banks, making Switzerland a hub for substantial financial capital used for investments.


7. United States
The United States, officially the United States of America, is a constitutional federal republic consisting of 50 states and one federal district. It is located almost entirely in the Western Hemisphere, with 48 contiguous states, the capital city being Washington, D.C., and the largest city being New York. The country is positioned between the Pacific Ocean to the west, the Atlantic Ocean to the east, Canada to the north, and Mexico to the south.
Alaska, a state in the far northwest of North America, borders Canada to the east and Russia to the west across the Bering Strait. Hawaii, another state, lies in the middle of the Pacific Ocean. The U.S. also controls 14 overseas territories scattered throughout the Caribbean and the Pacific Ocean.
Covering 3.79 million square miles (9.83 million km²) and with a population of 327.1 million (as of 2018), the United States is either the third or fourth largest country by total area and ranks third in population worldwide. The country has no official ethnic group, instead being a melting pot of diverse nationalities, which makes it one of the most racially and culturally diverse nations on the planet, a result of waves of immigration from around the globe.
While many of the wealthiest nations today have smaller populations, it is remarkable that the world's largest economy, the United States, still maintains a per capita GDP of 64,770 USD despite a population of over 310 million. This success is primarily due to the robust, sustainable, and continuously growing industries within the country, which generate dynamic revenues for the economy.


8. Qatar
Qatar is a sovereign nation located in Southwest Asia, on the northeastern tip of the Arabian Peninsula, within the Persian Gulf. It shares a land border with Saudi Arabia to the south, while the rest of the country is surrounded by the Gulf. A strait in the Persian Gulf separates Qatar from neighboring Bahrain, and it also has maritime borders with the United Arab Emirates (UAE) to the south and Iran to the west.
After being under Ottoman rule, Qatar became a British protectorate in the early 20th century until it gained independence in 1971. The Al Thani family has ruled Qatar since the 19th century, with Sheikh Jassim bin Mohammed Al Thani, the founding father of modern Qatar, signing a treaty with the British Empire in 1868, confirming Qatar's autonomy.
Qatar operates as a hereditary monarchy, with the Emir as the head of state and a symbol of national unity. However, there has been ongoing debate as to whether Qatar is a constitutional or an absolute monarchy. In 2003, Qatar’s constitution was ratified in a public referendum, with nearly 98% of the population supporting it.
Qatar ranks at the top of the world’s wealthiest nations, with a per capita GDP of 134,620 USD. The country’s economy is heavily driven by its oil and gas industry, which accounts for 70% of its revenues, 60% of its GDP, and over 80% of its exports. Due to its immense wealth and thriving economy, Qatar was chosen to host the 2022 FIFA World Cup, making it the first Arab nation to have the honor of holding this global sporting event.


9. Luxembourg
Luxembourg is a small, landlocked country in Western Europe, bordered by Belgium, France, and Germany. It operates as a constitutional monarchy and parliamentary democracy, governed by a Grand Duke, making it the last remaining Grand Duchy in the world. The country boasts a highly developed economy, with the highest GDP per capita in the world at 107,206 USD per person annually.
Luxembourg is a founding member of the European Union, NATO, the United Nations, Benelux, and the Western European Union, reflecting its political integration in economic, political, and military spheres.

10. Singapore
Singapore is a city-state and island nation located in Southeast Asia. It sits off the southern tip of the Malay Peninsula, about 137 kilometers north of the equator. The country consists of the main diamond-shaped island and around 60 smaller islands. Singapore is separated from Peninsular Malaysia to the north by the Johor Strait and from Indonesia’s Riau Islands to the south by the Singapore Strait.
Singapore’s islands have been inhabited since the 2nd century AD and have been controlled by various local states. In 1819, British politician Stamford Raffles established modern Singapore as a trading post for the British East India Company, with permission from the Sultan of Johor.
The British took control of the island in 1824, and Singapore became part of the British Straits Settlements in 1826. With the growth of trade and maritime shipping, Singapore rapidly expanded. By 1900, it had become the most prosperous and modern port city in Southeast Asia, comparable to major international ports like Rotterdam, Kobe, Shanghai, and Hong Kong.
Though small in size, Singapore has climbed two places in the rankings, moving from 5th to 3rd, with a current GDP per capita of approximately 103,700 USD, five times higher than the global average. The country’s prosperity is driven by its chemical export industry, financial services, and an economic policy that fosters free-market development and innovation. Singapore also boasts the world’s second-busiest international port.
