Israel and the Palestinian territories comprise the major part of the Holy Land, a region of significant importances to all Abrahamic religions – Jews, Christians, Muslims and Baha'is.
The religious affiliation of Israeli Jews varies widely: a social survey for those over the age of 20 indicates that 55% say they are "traditional", while 20% consider themselves "secular Jews", 17% define themselves as "Religious Zionists"; 8% define themselves as "Haredi Jews". While the ultra-Orthodox, or Haredim, represented only 5% of Israel's population in 1990, they are expected to represent more than one-fifth of Israel's Jewish population by 2028.
Making up 16% of the population, Muslims constitute Israel's largest religious minority. About 2% of the population are Christian and 1.5% are Druze. The Christian population primarily comprises Arab Christians, but also includes post-Soviet immigrants and the Foreign Laborers of multinational origins and followers of Messianic Judaism, considered by most Christians and Jews to be a form of Christianity. Members of many other religious groups, including Buddhists and Hindus, maintain a presence in Israel, albeit in small numbers. Out of more than one million immigrants from the former Soviet Union in Israel, about 300,000 are considered not Jewish by the Orthodox rabbinate.
The city of Jerusalem is of special importance to Jews, Muslims and Christians as it is the home of sites that are pivotal to their religious beliefs, such as the Israeli-controlled Old City that incorporates the Western Wall and the Temple Mount, the Al-Aqsa Mosque and the Church of the Holy Sepulchre.
Other locations of religious importance in Israel are Nazareth (holy in Christianity as the site of the Annunciation of Mary), Tiberias and Safed (two of the Four Holy Cities in Judaism), the White Mosque in Ramla (holy in Islam as the shrine of the prophet Saleh), and the Church of Saint George in Lod (holy in Christianity and Islam
