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, and includes Anatolia, the Arabian Peninsula, Iran, Mesopotamia, the Armenian Highlands, the Levant, the island of Cyprus, the Sinai Peninsula, and the southern part of the Caucasus Region (Transcaucasia). 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. The area contains the vast majority of the similarly defined Middle East, but excluding most of Egypt and the northwestern part of Turkey, and including the southern part of the Caucasus. West Asia covers an area of , 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. Definition 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).
