Of Israel's estimated population of 5.2 million, about 82 percent are Jews and 18 percent are non-Jews. Of the non-Jews, 76 percent are Muslims, 15 percent are Arab Christians, and 9 percent are Druzes or members of other ethnic groups. The state of Israel, however, also occupies by force large portions of a disputed territory known as Palestine. This territory is claimed by the Arab Palestinians as their homeland. There are 4.5 million Palestinians in the world. Although not counted in Israel's population, about 2 million live in Israel and the occupied territories.
