American religion is as diverse as its population.
Most Americans consider themselves Christians. Almost 50% identify with Protestant Christianity, while approximately 20% identify with Roman Catholicism. However, only about 36% of Americans attend church regularly.
Many Christian sects with a worldwide presence have their origins in the USA, including Mormonism and the Jehovah's Witnesses.
Eastern religions continue to grow in the United States, including Buddhism and Hinduism. Often these faiths are combined with American secularism or syncretism so that the product is a notably "American form" of them.
Judaism and Islam are firmly rooted in America as well, though their numbers are smaller.
