UK FlagResearch carried out by Brierley Consultancy in the UK, and published in Church Statistics gives an insight into the membership of churches, the number of places of worship and ministers. Data was published for 2005-2010, together with forecasts up to 2025.

The British Religion in Numbers website has additional data on Christianity in the UK.

Also included on this page are statistics from the UK Censuses, which were held in 2011 and 2021, and the British Social Attitudes Surveys (1983-2018).


Key Findings

Belief in God - 2016

A poll by You Gov in December 2016 produced the following results for persons asked if they believe in God or a higher spiritual power:

I believe in either God or a higher spiritual power


I do not believe in either God or a higher spiritual power


I believe in some kind of spiritual power only


I am unsure of my belief regarding either of these


Some key findings from the Church Statistics1 report are:

  1. UK Church membership has declined from 10.6 million in 1930 to 5.5 Million in 2010, or as a percentage of the population; from about 30% to 11.2%.
    By 2013, this had declined further to 5.4 million (10.3%). If current trends continue, membership will fall to 8.4% of the population by 2025.2

  2. In England, membership is forecast to decline to 2.53 million (4.3% of the population) by 2025.

  3. Over the period 2005-2010, the major Christian denominations such as Anglican, Catholic and Presbyterian all saw falls in membership. Orthodox, Pentecostal and other new churches (Evangelical and Charismatic) on the other hand, saw an increase in membership.

  4. Church membership is declining in all four constituent countries of the UK, but in England the decline is relatively small, whereas the biggest decline appears to be in Scotland.

WIN/Gallup Survey (2014)/Pew Forum Surveys (2015-17)

A 2014 survey of approximately 64,000 people in 65 countries revealed the UK to be one of the world's most irreligious countries, with only 30% of those surveyed identifying as 'religious'. In contrast, 13% said they were convinced atheists and 53% of those surveyed said they were not religious.

General Statistics


A 2015 article published by the Spectator magazine, gives the following statistics for Christianity in the UK:

According to the UK Census, between 2001 and 2011 the number of Christians born in Britain fell by 5.3 million - about 10,000 a week. With a continued rate of decline at this level, the number of UK-born Christians would reduce to zero by 2067.

The British Social Attitudes Survey (BSAS) indicates that Anglicanism is declining faster than any other major denomination. With the current rate of decline, it would be set to disappear from Britain by 2033.

In 2014, 17% of persons identified as Anglicans in the BSAS:

Between 1983 and 2014, the percentage of British Catholics fell from 10 to 8%.
