The U.S. government estimates the total population at 5.5 million (midyear 2020 estimate). The Office of the UN High Commissioner for Refugees (UNHCR) and other organizations estimate the total population includes 4.5 million citizens and an estimated 1.5 million refugees fleeing the conflicts in Syria and Iraq, the vast majority of whom are Syrian, as well as a Palestinian refugee population present in the country for more than 70 years. United Nations Relief and Works Agency for Palestine Refugees in the Near East estimates there are more than 180,000 currently in the country.

Statistics Lebanon, an independent firm, estimates 67.8 percent of the citizen population is Muslim (31.9 percent Sunni, 31.2 percent Shia, and small percentages of Alawites and Ismailis). Statistics Lebanon estimates 32.4 percent of the population is Christian. Maronite Catholics are the largest Christian group, followed by Greek Orthodox. Other Christian groups include Greek Catholics (Melkites), Armenian Orthodox, Armenian Catholics, Syriac Orthodox, Syriac Catholics, Assyrians, Chaldean Catholics, Copts, Protestants (including Presbyterians, Baptists, and Seventh-day Adventists), Roman (Latin) Catholics, and members of The Church of Jesus Christ of Latter-day Saints (Church of Jesus Christ).

According to Statistics Lebanon, 4.5 percent of the population is Druze, concentrated in the rural, mountainous areas east and south of Beirut. There are also small numbers of Jews, Baha’is, Buddhists, and Hindus. The Jewish Community Council, which represents the country’s Jewish community, estimates 70 Jews reside in the country.

UNHCR reports that the refugees from Syria in the country are mainly Sunni Muslims, but also Shia Muslims, Christians, and Druze. Palestinians live in the country as UN-registered refugees in 12 camps and surrounding areas. They are mostly the descendants of refugees who entered the country in the 1940s and 1950s. Most are Sunni Muslims but some are Christians.

UNHCR states there are approximately 12,200 UNHCR-registered Iraqi refugees in the country. Refugees and foreign migrants from Iraq include mostly Sunni Kurds, Sunni and Shia Muslims, and Chaldeans. There are also Coptic Christians from Egypt and Sudan. According to the secretary-general of the Syriac League, a nongovernmental organization (NGO) that advocates for Syriac Christians in the country, approximately 4,000 Iraqi Christians of all denominations and 3,000 to 4,000 Coptic Christians reside in the country. According to the same NGO, the majority of Iraqi Christian refugees are not registered with UNHCR and so are not included in their count. The NGO noted that the population size of Iraqi Christians had decreased by 60 percent since 2019, largely because of emigration driven by the country’s economic crisis.

Persons from all religious groups emigrated from the country during the year, in large part due to the country’s deteriorating economic situation. There is anecdotal evidence that Christians constituted a significant portion of those who left the country, especially following the August 4 Beirut Port explosion, with some citing fears for their security and potential treatment in an unpredictable political environment as a reason for their departure.
