The U.S. government estimates the total population at 3.1 million (midyear 2019 estimate). According to the most recent census, conducted in 2011, Sunni Muslims constitute nearly 57 percent of the population, Roman Catholics 10 percent, members of the Autocephalous Orthodox Church of Albania nearly 7 percent, and members of the Bektashi Order (a form of Shia Sufism) 2 percent. Other groups include Protestant denominations, Baha’is, Jehovah’s Witnesses, The Church of Jesus Christ of Latter-day Saints, and a small Jewish community. Nearly 20 percent of respondents declined to answer the optional census question about religious affiliation.

The U.S. government estimates the total population at 80.3 million (midyear 2019 estimate). Unofficial estimates based on the census and figures provided by religious groups indicate approximately 28 percent of the population is Catholic, and 26 percent belongs to the EKD – a confederation of Lutheran, Reformed (Calvinist), and United (Prussian Union) Protestant regional churches. Other Protestant denominations, including the New Apostolic Church, Baptist communities, and nondenominational Christians, account for approximately 1 percent of the population. Orthodox Christians represent 1.9 percent of the population.

According to government estimates, approximately 5.3 percent of the population is Muslim, of which 75 percent is Sunni, 13 percent Alevi, and 7 percent Shia; the remainder includes Alawites (70,000), Ahmadis (35,000), and Sufis (10,000). Intelligence officials estimate there are approximately 11,300 Salafi Muslims in the country. According to the Ministry of Interior, approximately 25 percent of Muslims are recent immigrants; between 2011 and 2015, an estimated 1.2 million Muslim immigrants entered the country. Estimates of the Jewish population vary widely; the Central Council of Jews estimates it at 100,000, while other estimates place the number at approximately 200,000 when including Jews who do not belong to a specific Jewish community. According to the secular NGO Religious Studies Media and Information Service (REMID), Buddhists (270,000); Jehovah’s Witnesses (169,000); Hindus (100,000); Yezidis (100,000); The Church of Jesus Christ of Latter-day Saints (Church of Jesus Christ) (40,000); Sikhs (10,000-15,000); and Church of Scientology (COS) (3,400) together constitute less than 1 percent of the population. All of REMID’s estimates are based on members who have registered with a religious group. According to the nonprofit Research Group Worldviews Germany, approximately 39 percent of the population either has no religious affiliation or belongs to religious groups not counted in government statistics.
