46% Christian. 37% no religion. 6.5% Muslim. Real data, real change, real questions about Britain's religious future.
Before we look at Britain's religious landscape today, let's check what stuck from Lesson 2 (where we met the Big Six + One). No notes. No peeking.
Write down every fact you can remember about ANY FOUR of the seven worldviews from Lesson 2. One distinctive fact per worldview. Go.
What percentage of people in Britain do you THINK are Christian? Muslim? No religion? Write your guesses — just what feels right based on what you know about modern Britain.
Let's look at what Britain actually looks like, according to the 2021 Census — the most recent official count of the UK population.
The UK Census happens every 10 years and asks 28 million households about their religion, language, ethnicity, job, housing, and more. It's the largest survey in Britain.
What does this tell us? Christianity is still the largest religion. But "no religion" is now the second-largest group. Together they make up 83% of Britain.
2011: 59.3% → 2021: 46.2% — −13.1 percentage points. Nearly 7 million fewer people identified as Christian in a single decade.
2011: 24.7% → 2021: 37.2% — +12.5 percentage points. The biggest growth. Nearly 3.5 million more people said "no religion."
2011: 4.8% → 2021: 6.5% — +1.7 percentage points. Modest but steady growth through immigration, higher birth rates, and a younger Muslim population.
2011: 11.2% combined → 2021: 9.2% combined — −2 percentage points. Hinduism, Sikhism, Judaism, and Buddhism remain relatively stable.
Secularisation means the decline of religion's influence in society. Britain is increasingly secular — religion is becoming less central to life, institutions, and culture. Fewer people attend church regularly. This is especially true in younger generations.
Older generations (who grew up when church was normal) are dying, and younger generations are not becoming Christian. If you didn't learn Christianity as a child, you're less likely to adopt it as an adult.
Islam, Hinduism, and Sikhism have grown partly through migration from South Asia and the Middle East — communities bringing their religions with them.
Not everyone who says "no religion" is an atheist. Some believe in God or spirituality but don't follow any organised religion. Surveys suggest 10–15% of Brits fit this description.
A society with many different religions and worldviews coexisting. Modern Britain is religiously pluralistic — no single religion dominates.
Look back at your guesses from the Think tab. How did you do? Write down any surprises.
Numbers hide stories. Here are five worldviews told through real people living in Britain today. For each, identify which worldview category they fit, and which of Smart's dimensions you see active in their life.
British-Pakistani Muslim, works in medical research, wears hijab
Which worldview? Which of Smart's dimensions do you see?
British-Indian Sikh, retired, wears turban and uncut beard
Which worldview? Which dimensions are strongest?
Raised Anglican Christian, now says "spiritual but not religious"
Which category best describes Maya? Why might she be counted as "no religion"?
Irish Catholic priest, progressive views on women's ordination
Which worldview? What's unusual about Father Thomas's relationship with his tradition?
British-Hindu background, identifies as humanist/atheist
Which worldview(s)? Why might Asha's family find her choices challenging?
Create a summary of Britain's religious landscape. Written (100+ words) or a labelled visual description.
At least 5 specific facts from the 2021 Census data. Both religious traditions AND non-religious worldviews. A clear explanation of ONE reason why the picture is changing (secularisation, generational change, immigration, etc.). Respectful, accurate language.
"Britain is becoming less religious. Is this a good thing or a bad thing?"
There are no simple answers. Build an argument. Consider multiple viewpoints. Then decide.
Step 1 — Arguments FOR (secularisation is positive):
Freedom from dogma? More equality? More science-based policy? More individual choice?
Step 2 — Arguments AGAINST (secularisation is problematic):
What might we lose? Community? Moral framework? Meaning and purpose?
Step 3 — Your balanced view:
These questions mix today with earlier lessons. No looking back.
1. (Lesson 2) What are the "Abrahamic faiths" and why are they called that?
2. (Today) What percentage of Britain said "no religion" in 2021?
3. (Lesson 1) Name three of Ninian Smart's seven dimensions of religion.
4. (Today) Explain the difference between "secularisation" and "pluralism."
5. (Lesson 2) What's distinctive about the Sikh sacred text?
Close everything. This is the real test of what you know from today.
