<P> Religion in the United Kingdom (2011 census) </P> <P> Religion in the United Kingdom and in the countries that preceded it has been dominated, for over 1,400 years, by various forms of Christianity . Religious affiliations of United Kingdom citizens are recorded by regular surveys, the four major ones being the national decennial census, the Labour Force Survey, the British Social Attitudes survey and the European Social Survey . According to the 2011 Census, Christianity is the major religion, followed by Islam, Hinduism, Sikhism, Judaism and Buddhism in terms of number of adherents . Among Christians, Anglicans are the most common denomination, followed by the Catholic Church in the United Kingdom . This, and the relatively large number of individuals with nominal or no religious affiliations, has led commentators to variously describe the United Kingdom as a multi-faith and secularised society . </P> <P> The United Kingdom was formed by the union of previously independent countries in 1707, and consequently most of the largest religious groups do not have UK - wide organisational structures . While some groups have separate structures for the individual countries of the United Kingdom, others have a single structure covering England and Wales or Great Britain . Similarly, due to the relatively recent creation of Northern Ireland in 1921, most major religious groups in Northern Ireland are organised on an all - Ireland basis . </P>
