fall below 50% by the end of the century. If there is no emigration of citizens and no immigration to the United Kingdom ('natural change' scenario), then the White British would remain at around 80% of the population by 2051 and would still remain the majority by the end of the century, albeit a reduced percentage (roughly around 75 - 70%) A fifth estimate, made by the Philip Rees and the University of Leeds, estimate that if assumptions about ethnic self-identification are taken into account, and that there is a net outflow of citizens at 38,000 a year, most of which are non-white and long term net migration like mentioned turns negative, this would result in the White British remaining at around 80% of the population by 2051, 20% of which would be ethnic minorities and 15% of that 20% would be non-white. Religion In 2001, the question of religious adherence was asked for the first time since 1851 in the United Kingdom Census. The traditional religion in the United Kingdom is Christianity. In England the established church is the Church of England (Anglican). In Scotland, the Church of Scotland (a Presbyterian Church) is regarded as the 'national church' but there is not an established church. In Wales there is no established church, with the Church in Wales having been disestablished in 1920. Likewise, in Ireland, the Church of Ireland was disestablished in 1871. In Northern Ireland and parts of Western Scotland there are lingering sectarian divides between Roman Catholic and Protestant communities. The table below shows data regarding religion for the 2001 and 2011 censuses: In the 2011 Census, rather than select one of the specified religions offered on the Census form, many people chose to write in their own religion. Some of these religions were reassigned to one of the main religions offered. In England and Wales, 241,000 people belonged to religious groups which did not fall into any of the main religions. The largest of these were Pagans (56,620), Spiritualists (39,061) and Jains (20,288). Despite its high-profile nature there were only 2,418 Scientologists. The census also recorded 176,632 people stating their religion as Jedi Knight and 6,242 people as Heavy Metal after a campaign by Metal Hammer. These returns were classified as "No religion", along with Atheist, Agnostic, Humanist, and Free Thinker. Those who ticked Heathen who had been categorised as no religion in 2001 were categorised
