The Countries Portal

A country is a distinct part of the world, such as a state, nation, or other political entity. When referring to a specific polity, the term "country" may refer to a sovereign state, states with limited recognition, constituent country, or a dependent territory. Most sovereign states, but not all countries, are members of the United Nations. There is no universal agreement on the number of "countries" in the world since several states have disputed sovereignty status, limited recognition and a number of non-sovereign entities are commonly called countries.

The definition and usage of the word "country" are flexible and has changed over time. The Economist wrote in 2010 that "any attempt to find a clear definition of a country soon runs into a thicket of exceptions and anomalies."

Areas much smaller than a political entity may be referred to as a "country", such as the West Country in England, "big sky country" (used in various contexts of the American West), "coal country" (used to describe coal-mining regions), or simply "the country" (used to describe a rural area). The term "country" is also used as a qualifier descriptively, such as country music or country living. (Full article...)

China, officially the People's Republic of China (PRC), is a country in East Asia. With a population exceeding 1.4 billion, it is the world's second-most populous country. China spans the equivalent of five time zones and borders fourteen countries by land. With an area of nearly 9.6 million square kilometers (3,700,000 sq mi), it is the third-largest country by total land area. The country is divided into 33 province-level divisions: 22 provinces, five autonomous regions, four municipalities, and two semi-autonomous special administrative regions. Beijing is the national capital, while Shanghai is its most populous city and largest financial center.

One of the cradles of civilization, China has been inhabited since the Paleolithic era, with the earliest dynasties emerging in the Yellow River basin before the late second millennium BCE. The eighth to third centuries BCE saw a breakdown in the authority of the Zhou dynasty, accompanied by the emergence of administrative and military techniques, literature, philosophy, and historiography. In 221 BCE, China was unified under an emperor for the first time. Appointed non-hereditary officials began ruling counties instead of the aristocracy, ushering in more than two millennia of imperial dynasties including the Qin, Han, Tang, Yuan, Ming, and Qing. With the invention of gunpowder and paper, the establishment of the Silk Road, and the building of the Great Wall, Chinese culture—including languages, traditions, architecture, philosophy and technology—flourished and has heavily influenced East Asia and beyond.

Left-hand traffic (LHT) and right-hand traffic (RHT) are the practices, in bidirectional traffic, of keeping to the left side and to the right side of the road, respectively. They are fundamental to traffic flow, and are sometimes called the rule of the road. The terms right- and left-hand drive refer to the position of the driver and the steering wheel in the vehicle and are, in automobiles, the reverse of the terms right- and left-hand traffic. The rule also includes where on the road a vehicle is to be driven, if there is room for more than one vehicle in the one direction, and the side on which the vehicle in the rear overtakes the one in the front. For example, a driver in an LHT country would typically overtake on the right of the vehicle being overtaken.

RHT is used in 165 countries and territories, mainly in the Americas, Continental Europe, northern Africa and mainland Asia (except South Asia), while 75 countries use LHT, which account for about a sixth of the world's land area, a quarter of its roads, and about a third of its population. In 1919, 104 of the world's territories were LHT and an equal number were RHT. Between 1919 and 1986, 34 of the LHT territories switched to RHT. (Full article...)

Costa Rica (UK: /ˌkɒstə ˈriːkə/, US: /ˌkoʊstə-/ ^ⓘ; Spanish: [ˈkosta ˈrika]; literally "Rich Coast"), officially the Republic of Costa Rica, is a country in the Central American region of North America. Costa Rica is bordered by Nicaragua to the north, the Caribbean Sea to the northeast, Panama to the southeast, and the Pacific Ocean to the southwest, as well as maritime border with Ecuador to the south of Cocos Island. It has a population of around five million0 in a land area of 51,060 km² (19,710 sq mi). An estimated 333,980 people live in the capital and largest city, San José, with around two million people in the surrounding metropolitan area.

The sovereign state is a unitary presidential constitutional republic. It has a long-standing and stable democracy and a highly educated workforce. The country spends roughly 6.9% of its budget (2016) on education, compared to a global average of 4.4%. Its economy, once heavily dependent on agriculture, has diversified to include sectors such as finance, corporate services for foreign companies, pharmaceuticals, and ecotourism. Many foreign manufacturing and services companies operate in Costa Rica's Free Trade Zones (FTZ) where they benefit from investment and tax incentives. (Full article...)

The United States of America (USA or U.S.A.), commonly known as the United States (US or U.S.) or America, is a country primarily located in North America. It is a federation of 50 states, a federal capital district (Washington, D.C.), and 326 Indian reservations. Outside the union of states, it asserts sovereignty over five major unincorporated island territories and various uninhabited islands. The country has the world's third-largest land area, second-largest exclusive economic zone, and third-largest population, exceeding 334 million.

Paleo-Indians migrated across the Bering land bridge more than 12,000 years ago. British colonization led to the first settlement of the Thirteen Colonies in Virginia in 1607. Clashes with the British Crown over taxation and political representation sparked the American Revolution, with the Second Continental Congress formally declaring independence on July 4, 1776. Following its victory in the Revolutionary War (1775–1783), the country continued to expand across North America. As more states were admitted, sectional division over slavery led to the secession of the Confederate States of America, which fought the remaining states of the Union during the 1861–1865 American Civil War. With the Union's victory and preservation, slavery was abolished nationally. By 1890, the United States had established itself as a great power. After Japan's attack on Pearl Harbor in December 1941, the U.S. entered World War II. The aftermath of the war left the U.S. and the Soviet Union as the world's two superpowers and led to the Cold War, during which both countries engaged in a struggle for ideological dominance and international influence. Following the Soviet Union's collapse and the end of the Cold War in 1991, the U.S. emerged as the world's sole superpower.

The U.S. national government is a presidential constitutional republic and liberal democracy with three separate branches: legislative, executive, and judicial. It has a bicameral national legislature composed of the House of Representatives, a lower house based on population; and the Senate, an upper house based on equal representation for each state. Substantial autonomy is given to states and several territories, with a political culture that emphasizes liberty, equality under the law, individualism, and limited government. (Full article...)

Iran, officially the Islamic Republic of Iran (IRI), also known by its Western-given name Persia, is a country in West Asia. It is bordered by Iraq to the west and Turkey to the northwest, Azerbaijan, Armenia, the Caspian Sea and Turkmenistan to the north, Afghanistan to the east, Pakistan to the southeast, the Gulf of Oman and the Persian Gulf to the south. With a mostly Persian-ethnic population of almost 90 million in an area of 1,648,195 km² (636,372 sq mi), Iran ranks 17th globally in both geographic size and population. It is the sixth-largest country entirely in Asia, the second-largest in West Asia, and one of the world's most mountainous countries. Officially an Islamic republic, Iran has a Muslim-majority population. The country is divided into five regions with 31 provinces. The nation's capital and most populous city is Tehran, with around 16 million people in its metropolitan area. Other major cities include Mashhad, Isfahan, Karaj, and Shiraz.

Iran is one of the world's oldest civilizations, beginning with the Elamites in the fourth millennium BC. It was first unified as a state by the Medes in the seventh century BC and reached its territorial height in the sixth century BC, when Cyrus the Great founded the Achaemenid Empire, one of the largest and most powerful empires in ancient history. Alexander the Great conquered the empire in the fourth century BC, subsequently dividing Iran into several Hellenistic states. An Iranian rebellion established the Parthian Empire in the third century BC, which was succeeded in the third century AD by the Sasanian Empire. Muslims conquered the region in the seventh century AD, leading to Iran's Islamization. Iran became a major centre of Islamic culture and learning, and its culture, language, and customs spread across the Muslim world. A series of native Iranian Muslim dynasties ruled the country until the Seljuk and the Mongol conquests of the 11th to 14th centuries. In the 16th century, the native Safavids re-established a unified Iranian state with Twelver Shia Islam as the official religion, marking the beginning of modern Iranian history.

During the Afsharid Empire in the 18th century, Iran was a leading world power, though by the 19th century, it had lost significant territory through a series of conflicts with the Russian Empire. The early 20th century saw the Persian Constitutional Revolution and the establishment of the Pahlavi dynasty. Attempts by Mohammad Mosaddegh to nationalize the country's vast fossil fuel supply led to an Anglo-American coup in 1953. After the Iranian Revolution, the monarchy was overthrown in 1979 and the Islamic Republic of Iran was established by The Grand Ayatollah Ruhollah Khomeini, who became the country's first supreme leader. The forces of Saddam Hussein invaded the Iranian province of Khuzestan in 1980, initiating the Iran-Iraq War, which by the end of it in 1988, became the longest conventional war of the 20th century. Iran is officially governed as an Islamic Republic with a presidential system, albeit with ultimate authority vested in a supreme leader (rahbar), currently Ali Khamenei since Khomeini's death in 1989. The Iranian government has attracted criticism for its constraints and violations of human rights. (Full article...)

India, officially the Republic of India (ISO: Bhārat Gaṇarājya), is a country in South Asia. It is the seventh-largest country by area; the most populous country as of June 2023; and from the time of its independence in 1947, the world's most populous democracy. Bounded by the Indian Ocean on the south, the Arabian Sea on the southwest, and the Bay of Bengal on the southeast, it shares land borders with Pakistan to the west; China, Nepal, and Bhutan to the north; and Bangladesh and Myanmar to the east. In the Indian Ocean, India is in the vicinity of Sri Lanka and the Maldives; its Andaman and Nicobar Islands share a maritime border with Thailand, Myanmar, and Indonesia.

Modern humans arrived on the Indian subcontinent from Africa no later than 55,000 years ago.
Their long occupation, initially in varying forms of isolation as hunter-gatherers, has made the region highly diverse, second only to Africa in human genetic diversity. Settled life emerged on the subcontinent in the western margins of the Indus river basin 9,000 years ago, evolving gradually into the Indus Valley Civilisation of the third millennium BCE.
By 1200 BCE, an archaic form of Sanskrit, an Indo-European language, had diffused into India from the northwest. Its evidence today is found in the hymns of the Rigveda. Preserved by an oral tradition that was resolutely vigilant, the Rigveda records the dawning of Hinduism in India. The Dravidian languages of India were supplanted in the northern and western regions.
By 400 BCE, stratification and exclusion by caste had emerged within Hinduism,
and Buddhism and Jainism had arisen, proclaiming social orders unlinked to heredity.
Early political consolidations gave rise to the loose-knit Maurya and Gupta Empires based in the Ganges Basin.
Their collective era was suffused with wide-ranging creativity, but also marked by the declining status of women, and the incorporation of untouchability into an organised system of belief. In South India, the Middle kingdoms exported Dravidian-languages scripts and religious cultures to the kingdoms of Southeast Asia.

In the early medieval era, Christianity, Islam, Judaism, and Zoroastrianism became established on India's southern and western coasts.
Muslim armies from Central Asia intermittently overran India's northern plains,
eventually founding the Delhi Sultanate, and drawing northern India into the cosmopolitan networks of medieval Islam.
In the 15th century, the Vijayanagara Empire created a long-lasting composite Hindu culture in south India.
In the Punjab, Sikhism emerged, rejecting institutionalised religion.
The Mughal Empire, in 1526, ushered in two centuries of relative peace,
leaving a legacy of luminous architecture.
Gradually expanding rule of the British East India Company followed, turning India into a colonial economy, but also consolidating its sovereignty. British Crown rule began in 1858. The rights promised to Indians were granted slowly, but technological changes were introduced, and modern ideas of education and the public life took root. A pioneering and influential nationalist movement emerged, which was noted for nonviolent resistance and became the major factor in ending British rule. In 1947 the British Indian Empire was partitioned into two independent dominions, a Hindu-majority Dominion of India and a Muslim-majority Dominion of Pakistan, amid large-scale loss of life and an unprecedented migration.

Israel, officially the State of Israel, is a country in the Southern Levant region of West Asia. It is bordered by Lebanon to the north, Syria to the northeast, Jordan to the east, the Red Sea to the south, Egypt to the southwest, the Mediterranean Sea to the west, and the Palestinian territories – the West Bank along the east and the Gaza Strip along the southwest. Tel Aviv is the country's financial, economic, and technological center. Israel's governmental seat is in its proclaimed capital of Jerusalem, although Israeli sovereignty over East Jerusalem is of limited international recognition.

Israel is located in a region known historically as Canaan, Palestine, and the Holy Land. In antiquity, it was home to several Canaanite, and later, Israelite and Judahite states, and is referred to as the Land of Israel in Jewish tradition. Situated at a continental crossroad, the region subsequently came under the rule of many different empires, and was gradually Islamized from the 7th century. The late 19th century saw the rise of Zionism in Europe, a movement seeking a Jewish homeland, which garnered British support during World War I. During the war, British occupation led to the setting up of Mandatory Palestine in 1920. Increased Jewish immigration combined with British colonial policy led to intercommunal conflict between Jews and Arabs. The 1947 UN Partition Plan triggered a civil war between the two groups, which saw the expulsion and flight of most of Mandatory Palestine's predominantly Arab population, known as the Nakba, A minority remained and became Arab citizens of Israel.

The State of Israel declared its establishment on 14 May 1948, the eve of the British termination of the Mandate. On 15 May 1948, the armies of neighboring Arab states invaded the area of former Mandatory Palestine, starting the First Arab–Israeli War. The 1949 Armistice Agreements established Israel's borders over most of the former Mandate territory. The rest, the West Bank and the Gaza Strip, were taken by Jordan and Egypt respectively. The 1967 Six-Day War saw Israel occupying the West Bank, Gaza Strip, Egyptian Sinai Peninsula and Syrian Golan Heights. The Israeli government has since established and continues to expand settlements across the occupied territories, actions which are deemed illegal under international law, and has annexed both East Jerusalem and the Golan Heights, actions which are largely unrecognized internationally. Since the 1973 Yom Kippur War, Israel has signed peace treaties with Egypt, returning the Sinai Peninsula, and with Jordan, and has more recently normalized relations with several Arab countries. However, international efforts to resolve the Israeli–Palestinian conflict have not succeeded. Israel's practices in its occupation of the Palestinian territories have drawn sustained international criticism along with accusations from human rights organizations and United Nations officials that it has committed war crimes and crimes against humanity against the Palestinian people.

The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) or Britain, is a country in Northwestern Europe, off the coast of the continental mainland. It comprises England, Scotland, Wales, and Northern Ireland. The UK includes the island of Great Britain, the north-eastern part of the island of Ireland, and most of the smaller islands within the British Isles. Northern Ireland shares a land border with the Republic of Ireland; otherwise, the United Kingdom is surrounded by the Atlantic Ocean, the North Sea, the English Channel, the Celtic Sea, and the Irish Sea. The total area of the United Kingdom is 94,354 square miles (244,376 km²), with an estimated population of nearly 67.6 million people in 2022.

In 1707, the Kingdom of England (which included Wales) and the Kingdom of Scotland united under the Treaty of Union to create the Kingdom of Great Britain. The Acts of Union 1800 incorporated the Kingdom of Ireland to create the United Kingdom of Great Britain and Ireland in 1801. Most of Ireland seceded from the UK in 1922 as the Irish Free State, and the Royal and Parliamentary Titles Act 1927 created the present name, the United Kingdom of Great Britain and Northern Ireland.

The UK became the first industrialised country and was the world's foremost power for the majority of the 19th and early 20th centuries, particularly during the "Pax Britannica" between 1815 and 1914. At its height in the 1920s, the British Empire encompassed almost a quarter of the world's landmass and population, and was the largest empire in history. However, its involvement in the First World War and the Second World War damaged Britain's economic power and a global wave of decolonisation led to the independence of most British colonies. British influence can be observed in the legal and political systems of many of its former colonies, and British culture remains globally influential, particularly in language, literature, music and sport. English is the world's most widely spoken language and the third-most spoken native language. (Full article...)

Russia, or the Russian Federation, is a country spanning Eastern Europe and North Asia. It is the largest country in the world by area, extending across eleven time zones and sharing land borders with fourteen countries. It is the world's ninth-most populous country and Europe's most populous country. Russia is a highly urbanized country consisting of 16 population centers with over million inhabitants. Its capital as well as its largest city is Moscow. Saint Petersburg is Russia's second-largest city and cultural capital.

The East Slavs emerged as a recognised group in Europe between the 3rd and 8th centuries CE. The first East Slavic state, Kievan Rus', arose in the 9th century, and in 988, it adopted Orthodox Christianity from the Byzantine Empire. Rus' ultimately disintegrated, with the Grand Duchy of Moscow growing to become the Tsardom of Russia. By the early 18th century, Russia had vastly expanded through conquest, annexation, and the efforts of Russian explorers, developing into the Russian Empire, which remains the third-largest empire in history. However, with the Russian Revolution in 1917, Russia's monarchic rule was abolished and eventually replaced by the Russian SFSR—the world's first constitutionally socialist state. Following the Russian Civil War, the Russian SFSR established the Soviet Union with three other Soviet republics, within which it was the largest and principal constituent. At the expense of millions of lives, the Soviet Union underwent rapid industrialisation in the 1930s and later played a decisive role for the Allies in World War II by leading large-scale efforts on the Eastern Front. With the onset of the Cold War, it competed with the United States for global ideological influence. The Soviet era of the 20th century saw some of the most significant Russian technological achievements, including the first human-made satellite and the first human expedition into outer space.

In 1991, the Russian SFSR emerged from the dissolution of the Soviet Union as the independent Russian Federation. A new constitution was adopted, which established a federal semi-presidential system. Since the turn of the century, Russia's political system has been dominated by Vladimir Putin, under whom the country has experienced democratic backsliding and a shift towards authoritarianism. Russia has been militarily involved in a number of conflicts in former Soviet states and other countries, including its war with Georgia in 2008 and annexation of Crimea in 2014 from neighbouring Ukraine, followed by the further annexation of four other regions in 2022 during an ongoing invasion.

China, officially the People's Republic of China (PRC), is a country in East Asia. With a population exceeding 1.4 billion, it is the world's second-most populous country. China spans the equivalent of five time zones and borders fourteen countries by land. With an area of nearly 9.6 million square kilometers (3,700,000 sq mi), it is the third-largest country by total land area. The country is divided into 33 province-level divisions: 22 provinces, five autonomous regions, four municipalities, and two semi-autonomous special administrative regions. Beijing is the national capital, while Shanghai is its most populous city and largest financial center.

One of the cradles of civilization, China has been inhabited since the Paleolithic era, with the earliest dynasties emerging in the Yellow River basin before the late second millennium BCE. The eighth to third centuries BCE saw a breakdown in the authority of the Zhou dynasty, accompanied by the emergence of administrative and military techniques, literature, philosophy, and historiography. In 221 BCE, China was unified under an emperor for the first time. Appointed non-hereditary officials began ruling counties instead of the aristocracy, ushering in more than two millennia of imperial dynasties including the Qin, Han, Tang, Yuan, Ming, and Qing. With the invention of gunpowder and paper, the establishment of the Silk Road, and the building of the Great Wall, Chinese culture—including languages, traditions, architecture, philosophy and technology—flourished and has heavily influenced East Asia and beyond.

After decades of struggle, the monarchy was overthrown in 1912 and the Republic of China (ROC) was established. Despite China's eventual victory in the Second Sino-Japanese War and the Pacific War in general, numerous atrocities such as the Nanjing Massacre left lasting effects on the country. Concurrently during this period, the Chinese Communist Party (CCP) and the Kuomintang (KMT) government were fighting sporadically since 1927, with a brief truce as a united front when Japan began invading the country. The second phase of the civil war resumed not long after Japan was defeated, and by 1949, the CCP had established control on most of the territories of the country. As the KMT retreated to Taiwan, the country was split with both sides claiming to be the sole legitimate government of China. After the land reforms, later attempts to realize communism failed—the Great Leap Forward led to a massive famine of millions of citizens, while the Cultural Revolution caused a chaotic period of persecution and zealous Maoist populism. In 1971, the PRC replaced the ROC as China's representation in the United Nations (UN). Following the Sino-Soviet split, the Shanghai Communiqué in 1972 marked the beginning of normalized relations with the United States. Economic reforms that began in 1978 led by reformists within the CCP moved the country away from a socialist planned economy toward an increasingly capitalist market economy, spurring significant economic growth, although liberal and democratic political reforms stalled after the June Fourth Incident in 1989.

Japan is an island country in East Asia. It is in the northwest Pacific Ocean and is bordered on the west by the Sea of Japan, extending from the Sea of Okhotsk in the north toward the East China Sea, Philippine Sea, and Taiwan in the south. Japan is a part of the Ring of Fire, and spans an archipelago of 14,125 islands, with the four main islands being Hokkaido, Honshu (the "mainland"), Shikoku, and Kyushu. Tokyo is the country's capital and largest city, followed by Yokohama, Osaka, Nagoya, Sapporo, Fukuoka, Kobe, and Kyoto.

The Japanese archipelago has been inhabited since the Upper Paleolithic (30,000 BC). Between the fourth and ninth centuries AD, the kingdoms of the region became unified under an emperor and the imperial court based in Heian-kyō. Beginning in the 12th century, political power was held by a series of military dictators (shōgun) and feudal lords (daimyō), and enforced by a class of warrior nobility (samurai). After a century-long period of civil war, the country was reunified in 1603 under the Tokugawa shogunate, which enacted an isolationist foreign policy. In 1854, a United States fleet forced Japan to open trade to the West, which led to the end of the shogunate and the restoration of imperial power in 1868. In the Meiji period, the Empire of Japan adopted a Western-modeled constitution, and pursued a program of industrialization and modernization. Amidst a rise in militarism and overseas colonization, Japan invaded China in 1937 and entered World War II as an Axis power in 1941. After suffering defeat in the Pacific War and two atomic bombings, Japan surrendered in 1945 and came under a seven-year Allied occupation, during which it adopted a new constitution.

Under the 1947 constitution, Japan has maintained a constitutional monarchy with a bicameral legislature, the National Diet. Japan is a developed country and a great power, with one of the largest economies by nominal GDP. Japan has renounced its right to declare war, though it maintains a self-defense force that ranks as one of the world's strongest militaries. A global leader in the automotive, robotics, and electronics industries, the country has made significant contributions to science and technology, and is one of the world's largest exporters and importers. It is part of multiple major international and intergovernmental institutions. Japan has over 125 million inhabitants and is the 11th most populous country in the world, as well as one of the most densely populated. About three-fourths of the country's terrain is mountainous, concentrating its highly urbanized population on narrow coastal plains. Japan is divided into 47 administrative prefectures and eight traditional regions. The Greater Tokyo Area is the most populous metropolitan area in the world. Japan has one of the world's longest life expectancies but has a population decline due to its very low birth rate. (Full article...)

Taiwan, officially the Republic of China (ROC), is a country in East Asia.
It is located at the junction of the East and South China Seas in the northwestern Pacific Ocean, with the People's Republic of China (PRC) to the northwest, Japan to the northeast, and the Philippines to the south. The territories controlled by the ROC consist of 168 islands with a combined area of 36,193 square kilometres (13,974 square miles). The main island of Taiwan, also known as Formosa, has an area of 35,808 square kilometres (13,826 square miles), with mountain ranges dominating the eastern two-thirds and plains in the western third, where its highly urbanized population is concentrated. The capital, Taipei, forms along with New Taipei City and Keelung the largest metropolitan area. With around 23.9 million inhabitants, Taiwan is among the most densely populated countries.

Taiwan has been settled for at least 25,000 years. Ancestors of Taiwanese indigenous peoples settled the island around 6,000 years ago. In the 17th century, large-scale Han Chinese immigration began under a Dutch colony and continued under the Kingdom of Tungning, the first predominantly Han Chinese state in Taiwanese history. The island was annexed in 1683 by the Qing dynasty of China and ceded to the Empire of Japan in 1895. The Republic of China, which had overthrown the Qing in 1912, took control following the surrender of Japan in 1945. Japan renounced sovereignty over Taiwan in 1952. The immediate resumption of the Chinese Civil War resulted in the loss of the Chinese mainland to Communist forces, who established the People's Republic of China, and the flight of the ROC central government to Taiwan in 1949. The effective jurisdiction of the ROC has since been limited to Taiwan, Penghu, and smaller islands.

In the early 1960s, Taiwan entered a period of rapid economic growth and industrialization called the "Taiwan Miracle". In the late 1980s and early 1990s, the ROC transitioned from a one-party state under martial law to a multi-party democracy, with democratically elected presidents since 1996. Taiwan's export-oriented industrial economy is the 21st-largest in the world by nominal GDP and the 20th-largest by PPP measures, with a focus on steel, machinery, electronics, and chemicals manufacturing. Taiwan is a developed country. It is ranked highly in terms of civil liberties, healthcare, and human development. (Full article...)

Gross domestic product (GDP) is the market value of all final goods and services from a nation in a given year. Countries are sorted by nominal GDP estimates from financial and statistical institutions, which are calculated at market or government official exchange rates. Nominal GDP does not take into account differences in the cost of living in different countries, and the results can vary greatly from one year to another based on fluctuations in the exchange rates of the country's currency. Such fluctuations may change a country's ranking from one year to the next, even though they often make little or no difference in the standard of living of its population.

Comparisons of national wealth are also frequently made based on purchasing power parity (PPP), to adjust for differences in the cost of living in different countries. Other metrics, nominal GDP per capita and a corresponding GDP (PPP) per capita are used for comparing national standard of living. On the whole, PPP per capita figures are less spread than nominal GDP per capita figures.

The rankings of national economies over time have changed considerably; the United States surpassed the British Empire's output around 1916, which in turn had surpassed the Qing dynasty in aggregate output decades earlier. Since China's transition to a socialist market economy through controlled privatisation and deregulation, the country has seen its ranking increase from ninth in 1978, to second in 2010; China's economic growth accelerated during this period and its share of global nominal GDP surged from 2% in 1980 to 18% in 2021. Among others, India has also experienced an economic boom since the implementation of economic liberalisation in the early 1990s. (Full article...)
