The U.S. government estimates the total population at 34.9 million (July 2018 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 245 Sikh and Hindu families totaling 700 individuals, down from 1,300 individuals estimated in 2017, mostly in Kabul, with a few communities in Nangarhar, Ghazni, Paktiya, Kunduz, Kandahar, and Helmand Provinces.

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 Jewish person.

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.
