The U.S. government estimates the total population at 37.9 million (midyear 2021).  According to the 2011 census, which has the most recent data available on religion, approximately 67 percent of the population self-identifies as Christian.  Roman Catholics constitute the largest Christian group (38 percent of the total population), followed by the United Church of Canada (6 percent), Anglicans (5 percent), Baptists (1.9 percent), and Christian Orthodox (1.7 percent).  Presbyterian, Lutheran, and Pentecostal groups each constitute less than 2 percent of the population.  The Church of Jesus Christ of Latter-day Saints estimates its membership at 199,000.  The Fundamentalist Church of Jesus Christ of Latter-day Saints (FLDS Church) estimates its membership at 1,000.  The Hutterites, or Hutterite Brethren, which number approximately 35,000, are an Anabaptist ethnoreligious group living primarily in Alberta, Manitoba, and Saskatchewan Provinces.  Approximately 3 percent of the population is Muslim, and 1 percent Jewish.  Buddhists, Hindus, Sikhs, Scientologists, Baha’is, and adherents of Shintoism, Taoism, and aboriginal spirituality together constitute less than 4 percent of the population.  Approximately 24 percent of the population list no religious affiliation.

The U.S. government estimates the total population at 5.9 million (midyear 2021).  As of the end of 2021, 73.2 percent of the Danish population were ELC members according to Statistics Denmark.  In 2021, 8,961 members left the ELC, representing the lowest yearly number who departed that church since 2007.  A church historian at the University of Copenhagen attributed this development to the pandemic, which highlighted the importance of religious communities.  The Danish government does not collect data on religious affiliation outside of the ELC.  A professor estimated in April 2020 that there are approximately 250,000 Muslims, accounting for 4.4 percent of the population.  Muslims are concentrated in the largest cities, particularly Copenhagen, Odense, and Aarhus.  The Ministry of Foreign Affairs estimates other religious groups, each constituting less than 1 percent of the population, to include, in descending order of size, Roman Catholics, Jehovah’s Witnesses, Serbian Orthodox Christians, Jews, Baptists, Buddhists, members of The Church of Jesus Christ of Latter-day Saints, Pentecostals, members of the Baha’i Faith, and nondenominational Christians.  According to a 2020 survey released by the Ministry of Immigration and Integration, approximately 11 percent of the population does not identify as belonging to a religious group or identifies as atheist.  The organization Jewish Community in Denmark estimates between 6,000 and 8,000 Jews live in the country, mostly in the Copenhagen area.

Multiple sources indicate the Muslim population has grown rapidly in recent years because of a significant inflow of immigrants.  Muslim religious leaders estimate the number of Muslims rose to 100,000 in 2018 (most recent data available), of which approximately 80 percent is Sunni and 20 percent Shia.  In 2017, the latest year for which statistics are available, the Pew Research Center estimated 2.7 percent of the population, or approximately 150,000 persons, were Muslim.  According to a survey by the Ministry of Education and Culture (MEC), the Muslim population numbered approximately 65,000 in 2016.  According to the Islamic Society of Finland, discrepancies among these sources and between them and official government statistics may occur because only a minority of Muslims register with registered Islamic societies.  Apart from Tatars, who immigrated in the late 19th and early 20th centuries as well as during the Soviet Union period, most Muslims are immigrants or descendants of immigrants who arrived in recent decades from Somalia, North Africa, Iraq, Afghanistan, the Balkans, Syria, Turkey, and Iran.  There are 300 registered members of the Ahmadi community, according to leaders of the Ahmadiyya Muslim Jamaat Finland.
