About 75% of the population of the West Bank consists of Sunni Muslim Palestinian Arabs, many of whom live in large, impoverished refugee camps; 17% are Jewish Israelis living in government-subsidized settlements; and the rest are mainly Christian Palestinian Arabs. Arabic, Hebrew, and English are spoken. The land in the N West Bank is fertile, and olives, citrus and other fruits, vegetables, beef, and dairy products are produced. Family businesses and small-scale industries manufacture such goods as architectural limestone, textiles, and handicrafts, although investment capital is paltry. The area is also dependent on work in neighboring Israel for employment. Real economic development has been stagnated by a lack of resources and often set back by the Arab-Israeli violence arising out of the occupation and in response to Palestinian attacks in Israel; Israeli control of roughly 50% of the region's land and over roads and other key segments of the infrastructure also has been an impediment to development of the Palestinian economy.
