what is the largest religious group in the united states
Religion in the United States The majority of U.S. adults self-identify as Christians, while close to a quarter claim no religious affiliation.[2] According to a 2014 study by the Pew Research Center, 70.6% of the adult population identified themselves as Christians, with 46.5% professing attendance at a variety of churches that could be considered Protestant, and 20.8% professing Catholic beliefs. The same study says that other religions (including Judaism, Buddhism, Hinduism, and Islam) collectively make up about 6% of the population. According to a 2012 survey by the Pew forum, 36% of U.S. adults state that they attend services nearly every week or more.[3] According to a 2016 Gallup poll, Mississippi (with 63% of its adult population described as very religious, saying that religion is important to them and attending religious services almost every week) is the most religious state in the country, while New Hampshire (with only 20% of its adult population described as very religious) is the least religious state.[4]
Islam by country Adherents of Islam constitute the world's second largest religious group. According to a study in 2015, Islam has 1.8 billion adherents, making up about 24% of the world population.[1] Most Muslims are either of two denominations: Sunni (80-90%, roughly 1.5 billion people)[2] or Shia (10â€“20%, roughly 170-340 million people).[3] Islam is the dominant religion in the Central Asia, Indonesia, Middle East, South Asia, North Africa, the Sahel[4][5][6][7] and some other parts of Asia.[8] The diverse Asia-Pacific region contains the highest number of Muslims in the world, easily surpassing the Middle East and North Africa.[9]
