The West Bank, including East Jerusalem, has a land area of 5,640 km2 plus a water area of 220 km2, consisting of the northwest quarter of the Dead Sea. As of July 2017 it has an estimated population of 2,747,943 Palestinians, and approximately 391,000 Israeli settlers, and approximately another 201,200 Israeli settlers in East Jerusalem. The international community considers Israeli settlements in the West Bank, including East Jerusalem, illegal under international law, though Israel disputes this. The International Court of Justice advisory ruling (2004) concluded that events that came after the 1967 occupation of the West Bank by Israel, including the Jerusalem Law, Israel's peace treaty with Jordan and the Oslo Accords, did not change the status of the West Bank (including East Jerusalem) as occupied territory with Israel as the occupying power.
The name West Bank is a translation of the Arabic term ad-Diffah I-Garbiyyah, given to the territory west of the Jordan River that fell, in 1948, under occupation and administration by Jordan, which subsequently annexed it in 1950. This annexation was considered illegal and was recognized only by Britain, Iraq and Pakistan. The term was chosen to differentiate the west bank of the River Jordan from the "east bank" of this river.
The neo-Latin name Cisjordan or Cis-Jordan (literally "on this side of the River Jordan") is the usual name for the territory in the Romance languages and Hungarian. The name West Bank, however, has become the standard usage for this geopolitical entity in English and some of the other Germanic languages since its creation following the Jordanian army's conquest.
In English, the name Cisjordan is occasionally used to designate the entire region between the Jordan River and the Mediterranean, particularly in the historical context of the British Mandate and earlier times. The analogous Transjordan (literally "on the other side of the River Jordan") has historically been used to designate the region now roughly comprising the state of Jordan, which lies to the east of the Jordan River.
