West Asia covers an area of 5,994,935 km2 (2,314,657 sq mi), with a population of about 313 million.[1][2] 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.
"Western Asia" was in use as a geographical term in the early 19th century, before "Near East" became current as a geopolitical concept.[18] 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.[19][20][21] 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.[22]
Use of the term in the context of contemporary geopolitics or world economy appears to date from at least the mid-1960s.[23]
Several major aquifers provide water to large portions of West Asia. In Saudi Arabia, two large aquifers of Palaeozoic and Triassic origins are located beneath the Jabal Tuwayq mountains and areas west to the Red Sea.[26][better source needed]Cretaceous and Eocene-origin aquifers are located beneath large portions of central and eastern Saudi Arabia, including Wasia and Biyadh which contain amounts of both fresh water and saline water.[26] Flood or furrow irrigation, as well as sprinkler methods, are extensively used for irrigation, covering nearly 90,000 km2 (35,000 sq mi) across West Asia for agriculture.[27] Also, the Tigris and Euphrates rivers contribute very well.
There are two wind phenomena in West Asia: the sharqi and the shamal. The sharqi (or sharki) is a wind that comes from the south and southeast. It is seasonal, lasting from April to early June, and comes again between late September and November. The winds are dry and dusty, with occasional gusts up to 80 kilometres per hour (50 miles per hour) and often kick up violent sand and dust storms that can carry sand a few thousand meters high, and can close down airports for short periods of time. These winds can last for a full day at the beginning and end of the season, and for several days during the middle of the season. The shamal is a summer northwesterly wind blowing over Iraq and the Persian Gulf states (including Saudi Arabia and Kuwait), often strong during the day, but decreasing at night. This weather effect occurs anywhere from once to several times a year.[29]
In Yemen, elevations exceed 3,700 m (12,100 ft) in many areas, and highland areas extend north along the Red Sea coast and north into Lebanon. A fault zone also exists along the Red Sea, with continental rifting creating trough-like topography with areas located well below sea level.[30] The Dead Sea, located on the border between the West Bank, Israel, and Jordan, is situated at 418 m (1,371 ft) below sea level, making it the lowest point on the surface of the Earth.[31]
Rub' al Khali, one of the world's largest sand deserts, spans the southern third of the Arabian Peninsula in Saudi Arabia, parts of Oman, the United Arab Emirates and Yemen. Jebel al Akhdar is a small range of mountains located in northeastern Oman, bordering the Gulf of Oman.
The population of West Asia was estimated at 272 million as of 2008, projected to reach 370 million by 2030 by Maddison (2007; the estimate excludes the Caucasus and Cyprus).
This corresponds to an annual growth rate of 1.4% (or a doubling time of 50 years), well above the world average of 0.9% (doubling time 75 years).
The population of West Asia is estimated at 4% of world population, up from about 39 million at the beginning of the 20th century, or about 2% of world population at the time.[32]
The most populous countries in the region are Turkey and Iran, each with around 79 million people, followed by Iraq and Saudi Arabia with around 33 million people each, and Yemen with around 29 million people.
Numerically, West Asia is predominantly Arab, Persian, Turkish, and the dominating languages are correspondingly Arabic, Persian and Turkish, each with of the order of 70 million speakers, followed by smaller communities of Kurdish, Azerbaijani, Hebrew, Armenian and Neo-Aramaic. The dominance of Arabic and Turkish is the result of the medieval Arab and Turkic invasions beginning with the Islamic conquests of the 7th century AD, which displaced the formerly dominant Aramaic in the region of Syria, and Greek in Anatolia, although Hebrew became the dominant language in Israel in the second half of the 20th century, and Neo-Aramaic (spoken by modern Arameans and Assyrians) and Greek both remain present in their respective territories as minority languages.
Judaism is the predominant religion in Israel, and there are small ancient Jewish communities in West Asia such as in Turkey (14,300),[45]Azerbaijan (9,100),[46] and Iran (8,756).[47]
The Druze Faith or Druzism originated in West Asia. It is a monotheistic religion based on the teachings of figures like Hamza ibn-'Ali ibn-Ahmad and Al-Hakim bi-Amr Allah and Greek philosophers such as Plato and Aristotle. The number of Druze people worldwide is around one million, with about 45% to 50% living in Syria, 35% to 40% living in Lebanon, and less than 10% living in Israel; recently there has been a growing Druze diaspora.[48]
The economy of West Asia is diverse and the region experiences high economic growth. Turkey has the largest economy in the region, followed by Saudi Arabia and Iran. Petroleum is the major industry in the regional economy, as more than half of the world's oil reserves and around 40 percent of the world's natural gasreserves are located in the region.

^ abJerusalem is Israel's de jure capital under Israeli law, as well as its de facto capital by the location of the presidential residence, government offices, supreme court and parliament (Knesset). Jerusalem is the State of Palestine's de jure capital under its "2003 Amended Basic Law". 17 February 2008, but not its de facto capital as its government branches are based in Ramallah. The UN and most sovereign states do not recognize Jerusalem as either state's de jure capital under the position that Jerusalem's status is pending future negotiations between Israel and the Palestinian Authority. In practice, therefore, most maintain their embassies in Tel Aviv and its suburbs, or else in suburbs such as Mevaseret Zion outside Jerusalem proper. See CIA Factbook, "Map of Israel"(PDF) and Status of Jerusalem for more information.
