The first British census to gather data on religion, in 2001, showed that there were 7.7 million irreligious people in the country. The wording of the question was criticised by humanist groups, and a revised question in the next census in 2011 counted 14.1 million irreligious people. This made irreligion the second-largest viewpoint on religion after Christianity, larger than the combined populations of non-Christian religions in the UK, and also the largest growth between the two censuses.
