Palestine is a name which has been widely used since Roman times to refer to the region between the Mediterranean Sea and the Jordan River. In its broader meaning as a geographical term, Palestine can refer to an area that includes contemporary Israel and the Palestinian territories, parts of Jordan, and parts of Lebanon and Syria. In its narrow meaning, it refers to the area within the boundaries of the former British Mandate of Palestine (1920-1948) west of the Jordan River. Palestine can also refer to the Proposed Palestinian State. Within the context of the Israeli-Palestinian conflict, the use of the term Palestine can arouse fierce controversy.
According to Israel's Central Bureau of Statistics, as of May 2006, of Israel's 7 million people, 77% were Jews, 18.5% Arabs, and 4.3% "others". Among Jews, 68% were Sabras (Israeli-born), mostly second- or third-generation Israelis, and the rest are olim — 22% from Europe and the Americas, and 10% from Asia and Africa, including the Arab countries.
According to Palestinian evaluations, The West Bank is inhabited by approximately 2.4 million Palestinians and the Gaza Strip by another 1.4 million. According to a study presented at The Sixth Herzliya Conference on The Balance of Israel's National Security there are 1.4 million Palestinians in the West Bank. This study was criticised by demographer Sergio DellaPergola, who estimated 3.33 million Palestinians in the West Bank and Gaza Strip combined at the end of 2005.
