Asia is the world's largest and most populous continent, located primarily in the eastern and northern hemispheres. It covers 8.6% of the Earth's total surface area (or 29.9% of its land area) and with approximately 4 billion people, it hosts 60% of the world's current human population.
Asia is traditionally defined as part of the landmass of Eurasia — with the western portion of the latter occupied by Europe — located to the east of the Suez Canal, east of the Ural Mountains and south of the Caucasus Mountains (or the Kuma-Manych Depression)[2] and the Caspian and Black Seas.[3] It is bounded on the east by the Pacific Ocean, on the south by the Indian Ocean and on the north by the Arctic Ocean. Given its size and diversity, Asia — a toponym dating back to classical antiquity — is more a cultural concept incorporating a number of regions and peoples than a homogeneous physical entity[2][4] (see Subregions of Asia, Asian people).
The wealth of Asia differs very widely among and within its regions, due to its vast size and huge range of different cultures, environments, historical ties and government systems. In terms of nominal GDP, Japan has the largest economy on the continent and the second largest in the world. In purchasing power parity terms, however, China has the largest economy in Asia and the second largest in the world.
Etymology
The term "Asia" is originally a concept exclusively of Western civilization.[5] The peoples of ancient Asia (Chinese, Japanese, Indians, Persians, Arabs etc.) never conceived the idea of Asia, simply because they did not see themselves collectively. In their perspective, they were vastly varied civilizations, contrary to ancient European belief.[5]
The word Asia originated from the Greek word Ἀσία, first attributed to Herodotus (about 440 BC) in reference to Anatolia or — in describing the Persian Wars — to the Persian Empire, in contrast to Greece and Egypt. Herodotus comments that he is puzzled as to why three women's names are used to describe one enormous and substantial land mass (Europa, Asia, and Libya, referring to Africa), stating that most Greeks assumed that Asia was named after the wife of Prometheus (i.e. Hesione), but that the Lydians say it was named after Asias, son of Cotys, who passed the name on to a tribe in Sardis. Even before Herodotus, Homer knew of two figures in the Trojan War named Asios; and elsewhere he describes a marsh as ασιος (Iliad 2, 461).
Usage of the term soon became common in ancient Greece, and subsequently by the ancient Romans.[5] Ancient and medieval European maps depict the Asian continent as a "huge amorphous blob" extending eastward.[5] It was presumed in antiquity to end with India — the Macedonian king Alexander the Great believing he would reach the "end of the world" upon his arrival in the East.[5]
Other alternatives
Alternatively, the etymology of the term may be from the Akkadian word (w)aṣû(m), which means 'to go outside' or 'to ascend', referring to the direction of the sun at sunrise in the Middle East and also likely connected with the Phoenician word asa meaning east. This may be contrasted to a similar etymology proposed for Europe, as being from Akkadian erēbu(m) 'to enter' or 'set' (of the sun).
T.R. Reid supports this alternative etymology, noting that the ancient Greek name must have derived from asu, meaning 'east' in Assyrian (ereb for Europe meaning 'west').[5] The ideas of Occidental (form Latin Occidens 'setting') and Oriental (from Latin Oriens for 'rising') are also European invention, synonymous with Western and Eastern.[5] Reid further emphasizes that it explains the Western point of view of placing all the peoples and cultures of Asia into a single classification, almost as if there were a need for setting the distinction between Western and Eastern civilizations on the Eurasian continent.[5] Ogura Kazuo and Tenshin Okakura are two Japanese outspoken figures over the subject.[5]
However, this etymology is considered doubtful, because it does not explain how the term "Asia" first came to be associated with Anatolia, which is west of the Semitic-speaking areas, unless they refer to the viewpoint of a Phoenician sailor sailing through the straits between the Mediterranean Sea and the Black Sea.
Definition and boundaries
Physical geography

Medieval Europeans considered Asia as a continent a distinct landmass. The European concept of the three continents in the Old World goes back to Classical Antiquity, but during the Middle Ages was notably due to 7th century Spanish scholar Isidore of Sevilla (see T and O map). The demarcation between Asia and Africa (to the southwest) is the Isthmus of Suez and the Red Sea. The boundary between Asia and Europe is conventionally considered to run through the Dardanelles, the Sea of Marmara, the Bosporus, the Black Sea, the Caucasus Mountains, the Caspian Sea, the Ural River to its source and the Ural Mountains to the Kara Sea near Kara, Russia. While this interpretation of tripartite continents (i.e., of Asia, Europe and Africa) remains common in modernity, discovery of the extent of Africa and Asia have made this definition somewhat anachronistic. This is especially true in the case of Asia, which has several regions that would be considered distinct landmasses if these criteria were used (for example, Southern Asia and Eastern Asia).
In the far northeast of Asia, Siberia is separated from North America by the Bering Strait. Asia is bounded on the south by the Indian Ocean (specifically, from west to east, the Gulf of Aden, Arabian Sea and Bay of Bengal), on the east by the waters of the Pacific Ocean (including, counterclockwise, the South China Sea, East China Sea, Yellow Sea, Sea of Japan, Sea of Okhotsk and Bering Sea) and on the north by the Arctic Ocean. Australia (or Oceania) is to the southeast.
Some geographers do not consider Asia and Europe to be separate continents,[6] as there is no logical physical separation between them.[4] For example, Sir Barry Cunliffe, the emeritus professor of European archeology at Oxford, argues that Europe has been geographically and culturally merely "the western excrescence of the continent of Asia."[7] Geographically, Asia is the major eastern constituent of the continent of Eurasia with Europe being a northwestern peninsula of the landmass – or of Afro-Eurasia: geologically, Asia, Europe and Africa comprise a single continuous landmass (save the Suez Canal) and share a common continental shelf. Almost all of Europe and most of Asia sit atop the Eurasian Plate, adjoined on the south by the Arabian and Indian Plate and with the easternmost part of Siberia (east of the Cherskiy Range) on the North American Plate.
In geography, there are two schools of thought. One school follows historical convention and treats Europe and Asia as different continents, categorizing subregions within them for more detailed analysis. The other school equates the word "continent" with a geographical region when referring to Europe, and use the term "region" to describe Asia in terms of physiography. Since, in linguistic terms, "continent" implies a distinct landmass, it is becoming increasingly common to substitute the term "region" for "continent" to avoid the problem of disambiguation altogether.
