West Asia

West Asia (also called Western Asia or Southwest Asia) is the westernmost region of Asia. As defined by most academics, UN bodies and other institutions, the subregion consists of Anatolia, the Arabian Peninsula, Iran, Mesopotamia, the Armenian highlands, the Levant, the island of Cyprus, the Sinai Peninsula and the South Caucasus. The region is separated from Africa by the Isthmus of Suez in Egypt, and separated from Europe by the waterways of the Turkish Straits and the watershed of the Greater Caucasus. Central Asia lies to its northeast, while South Asia lies to its east. Twelve seas surround the region (clockwise): the Aegean Sea, the Sea of Marmara, the Black Sea, the Caspian Sea, the Persian Gulf, the Gulf of Oman, the Arabian Sea, the Gulf of Aden, the Red Sea, the Gulf of Aqaba, the Gulf of Suez, and the Mediterranean Sea. West Asia contains the majority of the similarly defined Middle East. The Middle East is a political term invented by Western geographers that has historically included various territories depending on political and historical context, while West Asia is a geographical term with more accuracy and consistency. It excludes most of Egypt and the northwestern part of Turkey, and includes the southern part of the Caucasus.

West Asia covers an area of 5,994,935 km² (2,314,657 sq mi), with a population of about 313 million. Of the 20 UN member countries fully or partly within the region, 13 are part of the Arab world. The most populous countries in West Asia are Iran, Turkey, Iraq, Saudi Arabia and Yemen.

In the World Geographical Scheme for Recording Plant Distributions (WGSRPD), West Asia excludes the Arabian Peninsula and includes Afghanistan. The Food and Agriculture Organization (FAO) excludes Egypt and includes Afghanistan. The United Nations Environment Programme excludes Cyprus, Israel, Turkey, and Iran from West Asia.

The term West Asia is used pragmatically and has no "correct" or generally accepted definition. Its typical definitions overlap substantially, but not entirely, with definitions of the terms Middle East, Eastern Mediterranean, and Near East (which is historically familiar but widely deprecated today). The National Geographic Style Manual as well as Maddison's The World Economy: Historical Statistics (2003) by the Organisation for Economic Co-operation and Development (OECD) include only Bahrain, Iran, Iraq, Israel, Jordan, Kuwait, Lebanon, Oman, Qatar, Palestine (called West Bank and Gaza in the latter), Saudi Arabia, Syria, Turkey, UAE, and Yemen as West Asian countries. By contrast, the United Nations Industrial Development Organization (UNIDO) in its 2015 yearbook includes Armenia and Azerbaijan, and excludes Israel (as Other) and Turkey (as Europe).

Unlike the UNIDO, the United Nations Statistics Division (UNSD) excludes Iran from West Asia and includes Turkey, Georgia, and Cyprus in the region. In the United Nations geopolitical Eastern European Group, Armenia and Georgia are included in Eastern Europe, whereas Cyprus and East Thracian Turkey are in Southern Europe. These three nations are listed in the European category of the United Nations Educational, Scientific, and Cultural Organisation (UNESCO).

National members of West Asian sports governing bodies are limited to Bahrain, Iran, Iraq, Jordan, Kuwait, Lebanon, Syria, Oman, Palestine, Qatar, Saudi Arabia, United Arab Emirates, and Yemen. The Olympic Council of Asia's multi-sport event West Asian Games are contested by athletes representing these 13 countries. Among the region's sports organisations are the West Asia Basketball Association, West Asian Billiards and Snooker Federation, West Asian Football Federation, and the West Asian Tennis Federation.

Notes:
¹ Ramallah is the actual location of the government, whereas the proclaimed capital of Palestine is Jerusalem, which is disputed.
² Jerusalem is the proclaimed capital of Israel and the actual location of the Knesset, Israeli Supreme Court, etc. Due to its disputed status, most embassies are in Tel Aviv.
³ British Overseas Territory

"Western Asia" was in use as a geographical term in the early 19th century, before "Near East" became current as a geopolitical concept. In the context of the history of classical antiquity, "Western Asia" could mean the part of Asia known in classical antiquity, as opposed to the reaches of "interior Asia", i.e. Scythia, and "Eastern Asia" the easternmost reaches of geographical knowledge in classical authors, i.e. Transoxania and India. In the 20th century, "Western Asia" was used to denote a rough geographical era in the fields of archaeology and ancient history, especially as a shorthand for "the Fertile Crescent excluding Ancient Egypt" for the purposes of comparing the early civilizations of Egypt and the former.
