According to 2011 census information, the most recent available from Turkish Cypriot authorities, the population of the area administered by Turkish Cypriots is 286,000. The census contains no data on religious affiliation. Sociologists estimate as much as 97 percent of the population is Sunni Muslim. The Alevi Culture Association estimates that approximately 10,000 immigrants of Turkish, Kurdish, and Arab origin and their descendants are Alevi Muslims. The TSPA estimates there are 1,000 Turkish-speaking Protestants. The government of the Republic of Cyprus estimates 351 members of the Church of Cyprus and 308 Maronite Catholics reside in the area administered by Turkish Cypriots. According to sociologists, other groups include the Russian Orthodox, Anglican, Baha’i, Jewish, and Jehovah’s Witness communities. According to “Ministry of Education (MOE)” statistics for the 2020-21 academic year, there were approximately 80,000 foreign students enrolled at universities in the area administered by Turkish Cypriots. In November, authorities announced 37,000 of these students were no longer present in the north due to the pandemic, many having returned to their home countries to continue their education online. Of these, 60 percent were Muslim Turks and the rest were predominantly Christians and Muslims from more than 140 countries.

The U.S. government estimates the total population of the island at 1.3 million (midyear 2020 estimate). According to the 2011 census, the most recent, the population of the government-controlled area is 840,000. Of that total, 89.1 percent is Orthodox Christian and 2.9 percent is Roman Catholic, known locally as Latin. Other religious groups include Protestants (2 percent), Muslims (1.8 percent), Buddhists (1 percent), Maronite Catholics (0.5 percent), and Armenian Orthodox (0.3 percent), with small populations of Jews, Jehovah’s Witnesses, and Baha’is. The country’s chief rabbi estimates the number of Jews at 4,500, most of whom are foreign-born residents. A Jehovah’s Witnesses representative estimates the group has 2,600 members. Recent immigrants and migrant workers are predominantly Roman Catholic, Muslim, Hindu, and Buddhist.

The U.S. government estimates the total population at 8.7 million (midyear 2020 estimate). According to the country’s Central Bureau of Statistics (CBS) classification system, approximately 75 percent of the population is Jewish, 18 percent Muslim, 2 percent Christian, and 1.6 percent Druze. The remaining 4 percent consists of those the CBS classifies as “other.” This includes those who identify as Jewish but do not satisfy the Orthodox Jewish definition of “Jewish” the government uses for civil procedures, such as many immigrants from the former Soviet Union. There are also relatively small communities of Samaritans, Karaite Jews, Seventh-day Adventists, Messianic Jews, Jehovah’s Witnesses, and members of the Baha’i Faith. The majority of non-Jewish citizens are of Arab origin. This includes approximately 77 percent of the country’s 180,000 Christians, according to the CBS as of December. Non-Arab Christians are mainly those who emigrated from the former Soviet Union in the 1990s as descendants of Jews or alongside Jewish family members and their descendants.

According to the annual religion and state poll conducted by religious freedom NGO Hiddush, 60 percent of Jewish citizens do not affiliate with any religious group, 17 percent are “Zionist Orthodox,” 12 percent “ultra-Orthodox” (including 2 percent “Zionist ultra-Orthodox”), 7 percent “Reform,” and 4 percent “Conservative.”

Muslim, Druze, and Christian communities are located throughout the country. For example, in the Galilee region, some communities are homogenous, while others feature a mix of these groups. There are also dozens of Muslim-majority communities in the Negev. In addition to an Alawite community in Ghajar, there are several Druze communities in the Golan Heights.

The CBS estimates 563,200 Jews, 345,800 Muslims, and 12,850 Christians live in the current municipal boundaries of Jerusalem, accounting for approximately 99 percent of the city’s total population of 936,400 as of 2019.

According to government and NGO data, there are approximately 330,000 foreign workers in the country, including 97,000 documented Palestinian workers; 31,000 undocumented Palestinian workers; 98,000 migrant workers with permits, 77,000 non-Palestinian undocumented workers (either migrant workers without a permit or tourists who overstayed their visa); and 31,000 asylum seekers, of whom an unknown number work. Foreign workers and asylum seekers include Protestants, Roman Catholics, members of The Church of Jesus Christ of Latter-day Saints, Seventh-day Adventists, Orthodox Christians, Buddhists, Hindus, and Muslims. According to the Latin Patriarchate of Jerusalem, Catholics among the foreign worker population include 30,000 Filipinos, 15,000 Indians, 5,000 Sri Lankans, 2,500 Colombians, and 1,100 individuals from South American countries.

The U.S. government estimates the population at 10.9 million (midyear 2020 estimate). According to U.S. government estimates, Muslims, virtually all of whom are Sunni, make up 97.2 percent of the population. Some church leaders estimate Christians make up approximately 1.8 percent of the country’s population. Groups constituting less than 1 percent of the population include Buddhists, Baha’is, Hindus, and Druze (who are considered as Muslims by the government). According to the Royal Institute for Interfaith Studies (RIIFS), there is also a small community (consisting of a few families) of Zoroastrians. Most of the approximately one million migrant workers are from Egypt, South and Southeast Asia, and sub-Saharan Africa. Migrant workers from sub-Saharan Africa and South and Southeast Asia are often Christian or Hindu. There are an estimated 770,000 refugees registered with the UN High Commissioner for Refugees from 57 countries of origin, including more than 670,000 Syrians and 100,000 of other nationalities. The Syrian and Iraqi refugee populations are mostly Sunni Muslim. Shia Muslims and Christians account for less than one third of the Iraqi refugee population.

The U.S. government estimates the total population at 19.3 million (midyear 2020 estimate). At year’s end, more than half of the country’s prewar population was displaced; there were approximately 5.6 million refugees registered with the Office of the UN High Commissioner for Refugees in neighboring countries as well as 6.6 million IDPs. Continued population displacement adds a degree of uncertainty to demographic analyses, but the U.S. government estimates 74 percent of the population is Sunni Muslim, which includes ethnic Arabs, Kurds, Circassians, Chechens, and some Turkomans. According to U.S. government estimates, other Muslim groups, including Alawites, Ismailis, and Shia, together constitute 13 percent of the population, while Druze constitute 3 percent.

The U.S. government estimates 10 percent of the population is Christian. However, there are reports that indicate that number was considerably lower – approximately 2.5 percent. Of the 1.5 million Christians who lived in the country prior to the war, it is estimated that only approximately one-third of them – or approximately 450,000 – remain. Before the civil war, there were small Jewish populations in Aleppo and Damascus, but in June, the Jewish Chronicle reported that there were no known Jews still living in Syria. There was also a Yezidi population of approximately 80,000 before the civil war.

Sunni Muslims are present throughout the country. Shia Muslims live mostly in rural areas, particularly in several majority-Shia towns in Idlib and Aleppo Governates. Twelver Shia Muslims generally live in and around Damascus, Aleppo, and Homs. The majority of Alawites live in the mountainous areas of the coastal Latakia Governorate, but they also live in the cities of Latakia, Tartous, Homs, and Damascus. The highest concentration of Ismaili Muslims is in the city of Salamiyeh, Hama Governorate.

Most Christians belong to autonomous Orthodox Churches, Eastern Catholic Churches, or the Assyrian Church of the East and other affiliated independent Nestorian Churches. Most Christians continue to live in and around Damascus, Aleppo, Homs, Hama, and Latakia, or in the Hasakah Governorate in the northeast of the country. While there were hundreds of thousands of Iraqi Christian refugees before the conflict, the majority of the Iraqi Christian population has moved to neighboring countries or returned to Iraq. Many Druze live in the Jabal al-Arab (Jabal al-Druze) region in the southern Sweida Governorate, where they constitute a majority of the local population. Yezidis previously lived in Aleppo, but now live mainly in northeast Syria areas controlled by Kurdish-led Syrian Democratic Forces (SDF).

The U.S. government estimates the total Palestinian population at 2.9 million in the West Bank and 1.9 million in the Gaza Strip (midyear 2020 estimates). According to the U.S. government and other sources, Palestinian residents of these territories are predominantly Sunni Muslims, with small Shia and Ahmadi Muslim communities. The Israeli Central Bureau of Statistics reports an estimated 441,600 Jewish Israelis reside in Israeli settlements in the West Bank. According to various estimates, 50,000 Christian Palestinians reside in the West Bank and Jerusalem, and according to media reports and religious communities, there are at most 1,000 Christians residing in Gaza. According to local Christian leaders, Palestinian Christian emigration has continued at rapid rates. A majority of Christians are Greek Orthodox; the remainder includes Roman Catholics, Melkite Greek Catholics, Syrian Orthodox, Armenian Orthodox, Armenian Catholics, Coptic Orthodox, Maronites, Ethiopian Orthodox, Syrian Catholics, Episcopalians, Lutherans, other Protestant denominations, including evangelical Christians, and small numbers of members of The Church of Jesus Christ of Latter-day Saints and Jehovah’s Witnesses. Christians are concentrated primarily in Bethlehem, Ramallah, and Nablus; smaller communities exist elsewhere. Approximately 360 Samaritans (practitioners of Samaritanism, which is related to but distinct from Judaism) reside in the West Bank, primarily in the Nablus area.

The Israeli Central Bureau of Statistics estimates 563,200 Jews, 345,800 Muslims, and 12,850 Christians live in Jerusalem, accounting for approximately 99 percent of the city’s total population of 936,400, as of 2019.
