The Structure of Religion in the U.S.

Due to the First Amendment, which grants freedom of religion, there is a diversity of religious beliefs and practices in the U.S.

Religion in the United States is characterized by both a wide diversity in religious beliefs and practices and by a high adherence level.

Christianity is the largest religion in the United States, with around 77% of the population identifying itself as Christian.

Ecumenism mainly refers to initiatives aimed at creating greater Christian unity or cooperation.

Religion plays a "very important" role in the lives of most Americans; a proportion unique among developed nations.

Most modern Western societies are recognized as secular because they enjoy near-complete freedom of religion.
