and Shatila. There is also one within its municipal boundaries: Mar Elias. Southern suburban districts include Chiyah, Ghobeiry (Bir Hassan, Jnah and Ouzai are part of the Ghobeiry municipality), Haret Hreik, Burj al Barajneh, Laylake-Mreijeh, Hay al Sillum and Hadath. Eastern suburbs include Burj Hammoud, Sin el Fil, Dekwane and Mkalles. Hazmiyeh is also considered as an eastern suburb with its close proximity to the capital. Of the 15 unregistered or unofficial refugee camps, Sabra, which lies adjacent to Shatila, is also located in southern Beirut and was the scene of a massacre during the civil war. People in Lebanon often use different names for the same geographic locations, and few people rely on official, government-provided street numbers. Instead, historic and commercial landmarks are more commonly used. Demographics No population census has been taken in Lebanon since 1932, but estimates of Beirut's population range from as low as 938,940 through 1,303,129 to as high as 2,200,000 as part of Greater Beirut. Religion Beirut is one of the most cosmopolitan and religiously diverse cities of Lebanon and all of the Middle East. The city, which boasts substantial Muslim and Christian communities, hosts eighteen officially recognized religions: three Islamic sects: Shi'a, Sunni, and 'Alawi; one Druze sect; twelve Christian sects: Maronite Catholics, Greek Orthodox, Melkite Catholics, Protestant Evangelicals, and other Christian denominations non-native to Lebanon like Armenian Orthodox, Armenian Catholics, Assyrians (Syriac Orthodox, Syriac Catholic, Church of the East, Chaldean Catholic), Copts (recognized since the civil war); and Jews (very few remain in Lebanon today, but children of Lebanese Jewish parents may register as citizens at Lebanese Embassies). Christians comprise 35% of Beirut's population, Muslims 63%, Druze 1%, and others 1%. Family matters such as marriage, divorce and inheritance are still handled by the religious authorities representing a person's faith (the Ottoman "millet" system). Calls for civil marriage are unanimously rejected by the religious authorities, but civil marriages held in another country are recognized by Lebanese civil authorities. Before the civil war the neighborhoods of Beirut were fairly heterogeneous, but they became largely segregated by religion since the conflict. East Beirut has a mainly Christian population with a small Muslim minority, while West Beirut has a Sunni Muslim majority with small minorities of Shia, Christians and Druze. Since the end of the civil war, East and West Beirut have begun to see an increase in Muslims and Christians moving into each half.
