The U.S. government estimates the total population at 35.7 million (midyear 2019 estimate). There are no reliable statistics available concerning the percentages of Sunni and Shia Muslims in the country; the government’s Central Statistics Office does not track disaggregated population data. According to the Pew Forum, Shia make up approximately 10-15 percent of the population.

According to religious community leaders, the Shia population, approximately 90 percent of whom are ethnic Hazaras, is predominantly Jaafari, but it also includes Ismailis. Other religious groups, mainly Hindus, Sikhs, Baha’is, and Christians, constitute less than 0.3 percent of the population. Sikh and Hindu leaders estimate there are 120 Sikh and Hindu families totaling approximately 550 individuals, down from 700 in 2018 and 1,300 individuals estimated in 2017, mostly in Kabul, with a few communities in Nangarhar and Ghazni Provinces. Hindu community leaders estimate there are 35 remaining Afghan Hindus, all male and primarily businessmen with families in other countries.

The Ahmadi Muslim community estimates it has 450 adherents nationwide, down from 600 in 2017. Reliable estimates of the Baha’i and Christian communities are not available. There are small numbers of practitioners of other religions, including one Jew.

Hazaras live predominantly in the central and western provinces as well as in Kabul; Ismaili Muslims live mainly in Kabul and in the central and northern provinces. Followers of the Baha’i Faith live predominantly in Kabul, with a small community in Kandahar. Ahmadi Muslims largely live in Kabul.
