The 2021 Census reveals a historic shift in England and Wales – Christians now make up less than half the population. This milestone marks a defining change in UK’s religious identity. The numbers show Christianity dropping below 50% as more people identify themselves as non-religious.
Religious demographics in the UK tell the story of a changing nation. The data highlights the most important trends in UK’s main religion and shows greater religious diversity. More people now embrace secular beliefs. The 2021 Census findings help us understand these changes and what they mean to British society.
Key Findings from the 2021 Census
The 2021 Census data shows how the UK’s religious map has changed dramatically. 46.2% of the population (27.5 million people) now identify as Christian, showing a sharp drop of 13.1 percentage points from 59.3% in 2011.
Major Shifts in Religious Demographics
Recent census data emphasizes a remarkable increase in people choosing no religious affiliation. 37.2% of the population (22.2 million people) now report “No religion,” which represents a 12 percentage point increase from 2011. This change appears more evident among younger people, whose average age stands at 32 years.
Other religious communities have grown steadily. The Muslim population has reached 6.5% (3.9 million people), up from 4.9% in 2011. The Hindu population has also increased to 1.7% (1.0 million) from 1.5% in 2011.
Regional Variations Across the UK
London remains the UK’s most religiously diverse region, where 25.3% of residents follow religions other than Christianity. The North East and South West show minimal religious diversity, with just 4.2% and 3.2% of people identifying with non-Christian faiths respectively.
Notable regional patterns include:
- The North West, especially around Merseyside, has the highest concentration of Christians
- Welsh demographics reveal 46.5% reporting “No religion”
- Caerphilly (56.7%) and Blaenau Gwent (56.4%) lead the “No religion” responses
Comparison with Previous Census Data
Religious demographics have altered substantially between 2011 and 2021. The Christian population dropped by 5.5 million, while those reporting “No religion” grew by 8.5 million. Age plays a vital role in these changes. Christians have the highest average age at 51 years, while Muslims’ average age stands at 27 years.
Religious groups’ age differences have become more pronounced. The gap between Muslims (youngest) and Christians (oldest) has expanded from 20 years in 2011 to 24 years in 2021. These age patterns suggest future demographic changes will continue as younger generations express different religious preferences than their predecessors.
The Decline of Christianity
The Christian identity in England and Wales continues to fade away. This represents a radical alteration in the country’s religious makeup. A closer look at church attendance and population patterns shows just how deep this historic change runs.
Statistical Analysis of Christian Population
Christian affiliation has dropped steeply in the last two decades. The numbers tell a clear story – from a dominant 71.7% in 2001, Christian population has fallen to 46.2% in 2021. The community lost about 5.8 million members in just ten years, bringing the total down to 27.5 million people.
Factors Driving the Decline
Age demographics are vital to understanding this religious transformation. Christians tend to be older, and death rates affect their numbers by a lot. Professor Linda Woodhead of King’s College London explains that beyond natural population changes, religious beliefs aren’t being passed down between generations.
These reasons explain the decline:
- New generations think differently about religion
- Parents aren’t passing their faith to children
- People link religion with conservative values more often
- Younger people embrace secular views
Denominational Differences
Traditional churches feel the effects of declining religious membership most strongly. Church of England records show that 423 churches closed between 2010 and 2019. The total closures reached 940 between 1987 and 2019. Sunday service attendance keeps dropping and congregations are getting older.
Different regions show varying patterns of Christian decline across the country. The North West remains the most Christian, with places like Knowsley (66.6%), Ribble Valley (66.4%) and Copeland (65.1%) having the highest numbers of Christians. Wales shows a steeper drop with a 14.0 percentage point decrease between 2011 and 2021.
Research shows that children from Christian homes have a 45% chance of keeping their faith. Children from non-religious families are 95% likely to stay secular. This big difference in religious retention suggests fewer people will identify as Christian in future generations.
The Archbishop of York sees this change clearly. He notes that Britain has “left behind the era when many people almost automatically identified as Christian”. His words reflect a bigger change from cultural Christianity to a more diverse and secular society. Religious identity now comes from active choice rather than default assumption.

Rise of Religious Non-Affiliation
Religious demographics in the UK show a remarkable change as 37.2% of the population (22.2 million people) now say they have no religion.
Profile of the ‘No Religion’ Demographic
The non-religious population breaks down into three distinct groups:
- Spiritual Nones: These people embrace supernatural beliefs, with 80% holding such views and 61% seeing humans as spiritual beings
- Campaigning Nones: This group takes a strong atheistic stance, and 80% clearly state they don’t believe in God
- Tolerant Nones: They share atheistic beliefs but adopt a “live and let live” approach toward religion
The beliefs vary widely among non-religious people. 51% explicitly deny God’s existence, while 27% remain uncertain. Another 14% believe in a higher power rather than a personal god.
Generational Differences
Age shapes religious identification patterns significantly. Young adults aged 27 show the lowest religious affiliation, with 53% saying they have no religion. Wales shows even stronger trends, where 66% of 27-year-olds identify as non-religious.
Non-religious identity passes down through generations effectively. Studies show that almost all children of non-religious parents keep their non-religious identity. This contrasts sharply with religious households, where only half the children maintain their faith.
Geographic Distribution
Wales stands out as the least religious part of the UK. 46.5% of Welsh people identify as non-religious. Several areas in England and Wales show even higher numbers:
- Caerphilly: 56.7% non-religious
- Blaenau Gwent: 56.4% non-religious
- Rhondda Cynon Taf: 56.2% non-religious
Brighton and Hove leads England with 55.2% of its residents identifying as non-religious. London bucks this trend with the lowest proportion of non-religious people, likely because of its diverse faith communities.
The non-religious population’s makeup has changed by a lot. Earlier, young, well-educated males dominated this group. Recent data shows this difference fading. Men and women under 35 now show equal likelihood of being non-religious, with women making up 44-49% of the non-religious population.

Growing Religious Diversity
The UK’s religious landscape tells an interesting story. Christianity’s decline and rising non-religious identification happen alongside a growing diversity of faiths, especially in cities. The 2021 Census paints a picture of faith communities that are reshaping British society.
Growth of Minority Religions
Muslim communities have grown rapidly to 6.5% of the population (3.9 million people) in 2021, up from 4.9% in 2011. The Hindu population has expanded to 1.7% (1.0 million) from 1.5% in 2011. New religious movements keep attracting followers. Paganism now counts 74,000 believers across England and Wales.
The Muslim community stands out with its youthful profile. The average age of 27 years points to future growth through births and immigration. British Muslims come from many backgrounds – South Asian, Arabian Peninsula, African and Southeast Asian origins. The community also includes a rising number of British converts.
Impact of Immigration
New arrivals keep changing the UK’s religious makeup. Recent trends bring fresh perspectives to existing faith groups. The Chinese Christian community exemplifies this change. It has grown to 115,000 worshippers who gather in more than 200 churches.
Religion plays a bigger role among immigrants than British-born citizens. People born outside the UK are twice as likely to follow a religion. Only 18% say they have no religion, compared to 36% of the general population.
Urban-rural Differences
Religious diversity varies greatly between cities and countryside. Major cities showcase the richest mix of faiths:
- London tops the list with 25.3% of residents following non-Christian faiths
- Leicester, Luton, and Birmingham now have more ethnic minorities than white British residents
- Slough ranks highest outside London with two-thirds of its population being ethnic minorities
Rural areas tell a different story. The South West and North East remain more traditional, with just 3.2% and 4.2% of people following non-Christian faiths. Cities attract new arrivals while rural areas maintain their historical patterns.
This split shows up in religious buildings too. Cities offer more diverse places of worship and faith-based community groups. These institutions help religious communities grow stronger in urban areas, while rural regions stay more uniform.
British identity and social unity face new questions because of these patterns. London proves that different faiths can thrive together. Rural areas adapt more slowly to increasing diversity. The way religions spread across the UK shapes local communities and influences how policies develop nationwide.

Societal Implications
Religious changes in the UK are altering the map of British society. These changes affect everything from public institutions to how communities interact with each other. British society faces new challenges and opportunities in social unity and public services.
Changes in Social Institutions
British institutions now serve people of all faiths. The Places of Worship Scheme has allocated £24.5 million to protect mosques and Muslim schools. £3.5 million goes toward security needs of other religious communities. These numbers show how institutions now recognize religious diversity and security needs.
Employment numbers vary among religious groups. Muslim communities face unique challenges. Only 51.4% of working-age Muslims have jobs compared to the national average of 70.9%. Housing tells a similar story. Muslim families are nearly four times more likely to live in crowded homes than other Britons.
Impact on Education and Healthcare
Schools have adapted to welcome religious diversity:
- Religious Education (RE) now includes non-Christian religious practices
- State schools must stay neutral when teaching RE
- Daily worship remains mostly Christian, though families can opt out
Healthcare has evolved to meet everyone’s needs. Census data shows people in the “Other religion” category have higher disability rates (31.8%) than the national average of 17.5%. This group also has the most unpaid carers at 14.5%. These numbers show why targeted support services matter.
Community Cohesion Challenges
Religious dialog helps maintain social harmony. The Inter Faith Network started in 1987 and brings together nine major faiths to promote cooperation. Recent events have strained community relations, with more antisemitic and anti-Muslim incidents reported.
Local communities struggle with several issues:
- People move too often to build stable communities
- Language differences block cultural exchange
- Community spaces sit empty
- People tire of constant community surveys
The British Academy’s research shows faith groups build stronger communities. The growing non-religious population raises questions about traditional support networks. Online communities and new platforms might replace church-based community networks.
Government policies now emphasize faith-sensitive approaches in workplaces and schools. Understanding how beliefs shape attitudes and experiences is vital for social unity in modern Britain.
Housing statistics reveal ongoing gaps. Only 45.6% of Muslim households own their homes compared to 62.8% of all households. These differences create lasting challenges for community integration and growth.
Future Projections
The UK’s religious future looks set to change dramatically based on demographic projections. Research shows the nation’s spiritual identity will substantially evolve over the coming decades.
Demographic Trends and Predictions
Religious change continues at a rapid pace. By 2040, non-religious identities could make up 60% of the UK population. We noticed this change happens mostly because younger generations have different religious beliefs than their parents.
Key demographic predictions include:
- Christian populations will become minorities in several Western nations, including the UK, France and the Netherlands by 2050
- Muslims will represent one-in-nine Britons by 2050
- Birth rates will shape religious demographics – Muslim families have 3.1 children per woman compared to 2.7 for Christian families
Policy Implications
These religious changes mean policies must adapt in many sectors. Schools face unique challenges since 63% of people believe religions create more conflict than peace. This belief shapes discussions about religious education and faith schools.
People trust secular institutions more than ever. 85% of the population trusts university scientists, while faith in religious institutions declines. This reality calls for policies that balance:
- Religious freedom and expression
- Scientific advancement
- Social cohesion
- Educational curriculum development
The government now pushes “faith-sensitive” policies at work and in schools. This shows how religious understanding helps build harmony in our diverse society.
Social Transformation Outlook
The UK’s future religious makeup grows more complex each year. Research reveals children with no religious upbringing are 95% likely to stay non-religious. Children raised Christian have just a 45% chance of keeping their faith. These numbers point to more secularization ahead.
The story isn’t just about declining faith. Britain now has what experts call a “mosaic of religious beliefs”. Traditional churches might be emptying, but new spiritual paths are gaining ground. Shamanism grew from 650 followers in 2011 to 8,000 in 2021.
Religious identity’s link to social values keeps changing. 27% of people think society focuses too much on science over feelings and faith. Yet most accept different worldviews. This suggests a future where many beliefs exist side by side rather than one main view.
Immigration shapes religious demographics too. 80% of non-white Britons follow a religion, compared to 40% of white Britons. These numbers suggest future religious patterns will depend heavily on migration and ethnic diversity.
Changes reach beyond churches and affect how communities organize themselves. Religious buildings face uncertain futures, raising questions about their new roles in diverse neighborhoods. Society must find new ways to build the community bonds that religious groups once created.
Appreciate Religion in the UK
The UK’s religious demographics have reached a pivotal moment. Recent census data shows fundamental changes that are reshaping British society. The number of people identifying as Christian has declined, while religious diversity and secular worldviews continue to grow. These changes reflect how people’s relationship with faith and spirituality has transformed.
Current demographic trends indicate this religious development will persist. Young British people now choose non-religious identities or alternative spiritual paths more frequently. Immigration has added new layers to the country’s religious landscape. British institutions must adapt their services to meet the needs of diverse communities and maintain social cohesion.
These changes don’t signal the end of religion’s importance in British life. They point to a more nuanced future instead. Traditional religious structures might become less prominent, but new forms of spiritual expression and community organization have emerged. A clear understanding of these developments will help society prepare for a future where multiple worldviews coexist harmoniously.
