The U.S. government estimates the total population at 37.7 million (midyear 2020 estimate). 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, numbering 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 is 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 lists no religious affiliation.
