Religion in the United Kingdom is mainly expressed in Christianity, which dominated the land since the 7th century. Results of the 2021 Census for England and Wales showed that Christianity is the largest religion (though makes up less than half of the population), followed by the non-religious, Islam, Hinduism, Sikhism, Judaism, Buddhism, and Taoism.
Among Christians, Anglicanism[3] is the most common denomination, followed by Catholicism, Presbyterianism, Methodism, Unitarianism, and Baptism.
The Church of England is the state church of the largest member country, England. The Church of England defines itself as neither fully reformed Protestant nor fully Catholic. The Monarch of the United Kingdom is the supreme governor of the Church. The strictly Presbyterian Church of Scotland is likewise the official religion of Scotland. Both Northern Ireland and Wales have no state religion since the Irish Church Act 1869 and the Welsh Church Act 1914, respectively.
A large number of individuals have no religious affiliation, and many others are only nominally affiliated, and neither believe nor practice. Surveys find that agnosticism, nontheism, atheism and the like are views shared by a majority of Britons.[4] In addition to secularisation, post-WWII immigration turned the religious landscape more diverse, adding non-Christian beliefs and traditions and turning society somewhat multi-faith.
