In 2021, the largest religion in England and Wales was Christianity, with approximately 27.52 million adherents. Although Christianity was the largest religion, the number of followers has declined when compared with ten years earlier, when there were almost 33.27 million Christians.
In 2018 just over a third of people in the United Kingdom identified as being Christian, compared with two-thirds 25 years earlier in 1983. During this time period the proportion of people who identify as Christian has declined dramatically, while the proportion of irreligious people has grown,

This dataset provides Census 2021 estimates that classify usual residents in England and Wales by religion and by age. The estimates are as at Census Day, 21 March 2021.
Estimates for single year of age between ages 90 and 100+ are less reliable than other ages. Estimation and adjustment at these ages was based on the age range 90+ rather than five-year age bands. Read more about this quality notice.
Area type
Census 2021 statistics are published for a number of different geographies. These can be large, for example the whole of England, or small, for example an output area (OA), the lowest level of geography for which statistics are produced.
For higher levels of geography, more detailed statistics can be produced. When a lower level of geography is used, such as output areas (which have a minimum of 100 persons), the statistics produced have less detail. This is to protect the confidentiality of people and ensure that individuals or their characteristics cannot be identified.
Lower tier local authorities
Lower tier local authorities provide a range of local services. There are 309 lower tier local authorities in England made up of 181 non-metropolitan districts, 59 unitary authorities, 36 metropolitan districts and 33 London boroughs (including City of London). In Wales there are 22 local authorities made up of 22 unitary authorities.

Religious groups in the detailed religion classification
The counts for religious groups identified in the Religion (detailed) in England and Wales dataset are a representation of those who chose to write in their religion. Some people may have chosen to describe a denomination of one of the tick-box responses (for example, Catholic as a denomination of Christian or Orthodox as a denomination of Jewish) through the "Any other religion" write-in response option.
2011 Religion data
In 2011, an error in the processing of census data led to the number of usual residents in the “Religion not stated” category being overestimated by a total of 62,000 for the following three local authorities combined: Camden, Islington, and Tower Hamlets.
In February 2015, the ONS published corrected figures for estimates based on the tick-box classification. However, it could not be corrected for the detailed religion classification because the processing and relationships with other output variables are so complex.
For this reason, only apply comparisons for these three local authorities to the tick-box classification, using the corrected figures set out in the ONS 2011 Census products: Issues and corrections notice.
For this publication, where corrected figures for the tick-box classification from the 2011 Census are available, they have been used. Where they are not (for single year of age by sex), the ONS has used data from the CT0291_2011 commissioned table.

Religion
The 8 ‘tickbox’ religious groups are as follows:
General health
A person's assessment of the general state of their health from very good to very bad. This assessment is not based on a person's health over any specified period of time.
Disability
The definition of disability used in the 2021 Census is aligned with the definition of disability under the Equality Act (2010). A person is considered disabled if they self-report having a physical or mental health condition or illness that has lasted or is expected to last 12 months or more, and that this reduces their ability to carry out day-to-day activities.
Unpaid care
An unpaid carer may look after, give help or support to anyone who has long-term physical or mental ill-health conditions, illness or problems related to old age. This does not include any activities as part of paid employment. This help can be within or outside of the carer's household.
The census is undertaken by the Office for National Statistics every 10 years and gives us a picture of all the people and households in England and Wales. The most recent census took place in March of 2021.The census asks every household questions about the people who live there and the type of home they live in. In doing so, it helps to build a detailed snapshot of society. Information from the census helps the government and local authorities to plan and fund local services, such as education, doctors' surgeries and roads.Key census statistics for Leicester are published on the open data platform to make information accessible to local services, voluntary and community groups, and residents.Further information about the census and full datasets can be found on the ONS website - https://www.ons.gov.uk/census/aboutcensus/censusproductsReligionThis dataset provides Census 2021 estimates that classify usual residents in England and Wales by religion.

This statistic displays the religious affiliation of the people surveyed in the United Kingdom in 2017. Of the 2,010 individuals surveyed, 51 percent stated that they were Christian, this was the share number recorded. It was followed by 37 percent of individuals who stated that they were not affiliated with any religious group. Only one percent of respondents identified as Buddhist or Hindu.
Abstract copyright UK Data Service and data collection copyright owner. This source hails from the earlier years of large-scale survey research in Britain, with the electronic data file created following scanning of and data capture from original survey returns. The data collection provides insight into the lifestyles and religiosity of urban young people, predominantly working-class, at the dawn of the affluent society. It comprises a stratified random sample survey of the religious, social and associational lives of young people aged 15-24 in urban England in 1957. It was designed and fielded by the Newman Demographic Survey, a private research institute directed by religious sociologist Tony Spencer, in collaboration with Young Christian Workers, a faith-based youth organisation. The investigators aimed to yield a sample of English urban youth which would include at least 1000 Catholic respondents, representing all English Catholic dioceses. 8196 was achieved, of which following some apparently random data loss 5834 were of sufficient quality for scanning and data capture in 2010. The survey instrument consisted primarily of closed-form items piloted in Gateshead, Highgate and Manchester, and was designed following correspondence with specialist survey experts: Len England (1901-1999), Director of Mass Observation; Leslie Austen, director of Social Surveys (Gallup Poll) Ltd; and W.L. Readman at the National Food Survey at the Ministry of Agriculture, Fisheries and Food. John Mandeville of the British Tabulating Machine Company, a British-based company operating under licence to IBM, also provided advice to the survey investigators. The electoral register was used as the sampling frame, using a version of the 'nth page' method. To prevent interviewer fatigue, about half of the respondents (70% of Anglicans) completed a short version of the questionnaire, covering items on leisure and religious belief, while the remainder completed a longer version including items on associational memberships, schooling, religious attendance and practice, marital status, and parental country and religion of origin. Some written-in responses (on leisure, religious affiliation, associational memberships and occupation) have been captured. Design and post-stratification weights have been calculated for users. Main Topics: The religious, social and associational lives of young people aged 15-24 in urban England in 1957; their domestic circumstances, educational background and current working status. Multi-stage stratified random sample The investigators aimed to stratify the sample, at the first stage by the populations of urban areas by standard (now Government Office) region aged 15-24 as enumerated in the 1951 Census. Within each standard region they originally stratified according to the size of total population of boroughs, districts and local authorities as of 30 June 1955 divided as follows: 500,000 and more; 100,000-499,999; 50,000-99,999; 10,000-49,999; fewer than 10,000. Due to resource constraints, a first compromise was the decision not to cover authorities with smaller populations, as essentially comprising large villages and market towns. The sample universe was accordingly 'persons, in urban areas of England with population exceeding 50,000, age 15 to 24 inclusive'. The original aspiration to sample boroughs randomly was next abandoned as too resource-intensive. It had originally been hoped that the 'flying squad method' could be used, with smaller numbers of YCW volunteers travelling to areas where they were poorly-represented by car. Instead, boroughs were identified from a list of towns where the YCW had sections strong enough to field the survey without extensive additional help. Accordingly this probably introduced some bias in that the YCW was undoubtedly stronger in towns with higher proportions of Catholics and more active churches, congregations and clergy. This may reduce external validity somewhat. Within these boroughs, the electoral register was used as the sampling frame, using a version of the 'nth page' method. Where a household hosted more than one young person aged 15-24, it is not clear from the notes for interviewers how they were sampled. The number of residents aged 15-24 was however recorded for the creation of design weights. Face-to-face interview

This is known as statistical disclosure control. In Census 2021, they:
Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, they swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when they applied perturbation.For more geographies, aggregations or topics see the link in the Reference below.
