Religion in The United States

Religion in the United States is characterized by a diversity of religious beliefs and practices. Various religious faiths have flourished, as well as perished, in the United States. Religions that span the country's multicultural immigrant heritage, as well as those founded within the country, have led the United States to become one of the most religiously diverse countries in the world. A majority of Americans report that religion plays a "very important" role in their lives, a proportion unique among developed nations.

The majority of Americans (73%) identify themselves as Christians and about 20% have no religious affiliation. According to the American Religious Identification Survey (ARIS), those who identify themselves as Catholics make up about 25% of the adult population, while "other Christians" account for another 51%. The same survey says that other religions (including, for example, Judaism, Buddhism, Islam, and Hinduism) collectively make up about 4% of the adult population, another 15% of the adult population claim no religious affiliation, and 5.2% said they did not know, or they refused to reply. According to another survey, 36 percent of Americans state that they attend services nearly every week or more.

Despite a high level of religious adherence, only 9% of Americans in a 2008 poll said religion was the most important thing in their life, compared with 45% who said family was paramount in their life and 17% who said money and career was paramount.
