Religious Demography3

The country has an area of 402,356 square miles and a population of 31 million. Reliable data on religious demography is not available because an official nationwide census has not been conducted in decades. Observers estimate that 80 percent of the population is Sunni Muslim, 19 percent Shi'a Muslim, and other religious groups make up less than 1 percent of the population. There are approximately 2,200 Sikh and Hindu believers and more than 400 Baha'is. There is a small, hidden Christian community; estimates on its size range from 500 to 8,000. In addition, there are small numbers of adherents of other religious groups, mostly Buddhist foreigners.

Traditionally, the dominant religion is the sect of Sunni Islam that follows the Hanafi school of jurisprudence. For the last 200 years, much of the population adhered to Deobandi-influenced Hanafi Sunnism from Deoband, India, near Delhi. A sizable minority adhered to a more mystical version of Islam, generally known as Sufism. Sufism centers on orders or brotherhoods that follow charismatic religious leaders. During the 20th century, the influence of the Wahhabi form of Islam grew in certain regions.

Members of the same religious group have traditionally concentrated in certain regions. Some groups were displaced forcibly by kings for internal security reasons or to make agricultural and grazing land available to favored ethnic groups. Sunni Muslim Pashtuns dominate the south and east. The homeland of the Shi'a Hazaras is in the Hazarajat, the mountainous central highlands around Bamyan. Northeastern provinces traditionally have Ismaili populations. Other areas, including Kabul, the capital, are more heterogeneous and include Sunni, Shi'a, Hindu, Sikh, and Baha'i populations. The northern city of Mazar-e-Sharif includes a mix of Sunnis (including ethnic Pashtuns, Turkmen, Uzbeks, and Tajiks) and Shi'a (Hazaras and Qizilbash) including Shi'a Ismailis.

In the past, small communities of Hindus, Sikhs, Baha'is, Jews, and Christians lived in the country, although most members of these communities emigrated during the anti-Soviet jihad years of civil war and Taliban rule. Non-Muslim minorities were estimated to number in the hundreds at the end of Taliban rule. A small population of native Hindus and Sikhs never left. Since the fall of the Taliban, some members of religious minorities have returned, with many settling in Kabul.

Nuristanis, a small but distinct ethnolinguistic group living in a mountainous eastern region, practiced an ancient polytheistic religion until forcibly converted to Islam in the late 19th century. Some non-Muslim religious practices survive today as folk customs.

There are seven gurdwaras, Sikh places of worship, in Kabul. There are approximately six Hindu temples in four cities. An additional 18 were destroyed during the many years of war.

There is one Christian church and one synagogue. Some citizens who converted to Christianity as refugees have returned. Others Afghans living abroad may have been born abroad into other religious groups. The Baha'i faith has had followers in the country for approximately 150 years. The community is predominantly based in Kabul, where more than 300 Baha'i members live; another 100 are said to live in other parts of the country.


Note: The World Christian Database (WCD) estimates, used in the Religious Adherents section above, count each person as belonging to a maximum of one religious group. For more information, see the WCD methodology document. The U.S. State Department's International Religious Freedom report estimates, used in the Religious Demography section, use less restrictive criteria in which a person who identifies with more than one religion is classified as a follower of each. In certain cases (such as Japan and other nations with strong folk religion traditions), this can cause counts to vary widely between estimates. Users are advised to consult the relevant source documents before determining which counts to cite.

1.  The World Christian Database (WCD) is based on the 2600-page award-winning World Christian Encyclopedia and World Christian Trends, first published in 1982 and revised in 2001. This extensive work on World religion is now completely updated and integrated into the WCD online database. Designed for both the casual user and research scholar, information is readily available on religious activities, growth rates, religious literature, worker activity, and demographic statistics. Additional secular data is incorporated on population, health, education, and communications. A dataset with these and the other international measures highlighted on the country pages can be downloaded from this website. Used with permission.

2.  Estimates for the country were taken from the United States Department of State's Report on International Religious Freedom. "The International Religious Freedom report is submitted to Congress annually by the Department of State in compliance with Section 102(b) of the International Religious Freedom Act (IRFA) of 1998." The report profiles issues of religious adherence and freedom for each nation in the world. The information for each country was derived from a combination of "government and religious officials, nongovernmental organizations, journalists, human rights monitors, religious groups, and academics." Section I of each specific country report contains information on the religious demography of that nation. It is important to note that the estimates are of the proportion of national citizens (excluding resident non-nationals) who identify with specific religious traditions.

3.  The U.S. State Department's International Religious Freedom Report is submitted to Congress annually by the Department of State in compliance with Section 102(b) of the International Religious Freedom Act (IRFA) of 1998. This report supplements the most recent Human Rights Reports by providing additional detailed information with respect to matters involving international religious freedom. It includes individual country chapters on the status of religious freedom worldwide. A dataset with these and the other international measures highlighted on the country pages can be downloaded from this website. These State Department reports are open source.
