Fact check: What is the current Muslim population in England as of 2025?
Executive Summary
The most reliable, recent baseline for the Muslim population in England comes from the 2021 census and associated analyses: 3.9 million Muslims in England and Wales in 2021 (about 6.5% of the population), with England-only estimates clustered around 3.8–3.9 million. Contemporary 2025 references point to growth since 2011 and continuing demographic momentum, but no single source in the provided dataset gives a definitive 2025 headcount—estimates in the materials range from “about 3.8 million” to “over 4 million” depending on whether Wales is included and which intermediary estimates are used [1] [2] [3].
1. What the provided sources claim — headline figures that keep appearing and why they matter
The supplied analyses repeatedly cite the 2021 census figure of roughly 3.9 million Muslims in England and Wales, equating to about 6–6.5% of the population, and note a substantial increase from 2011 (a 43% rise) [1]. Some summaries translate that to an England-only figure of about 3.8–3.9 million, citing Church of England and other analyses that isolate England rather than England and Wales [2]. A separate media piece characterises British Muslims as “6 percent of the population,” a rounded figure that likely reflects England-only or UK rounding differences [4]. These recurring numbers form the factual backbone for any 2025 estimate.
2. Why different items in the dataset say “over 4 million” or similar — scope and rounding explain differences
One source notes a UK Muslim population “of over 4 million,” reflecting a broader geographic scope (UK rather than England or England and Wales) or using postcensal extrapolations [3]. The dataset shows that variations arise from whether the figure covers England only, England and Wales, or the entire UK, and whether the number is a census count or a later estimate. Media rounding conventions and different publication dates (mid-2025 to September 2025) also lead to small discrepancies between 3.8–4+ million assertions [3] [5].
3. How reliable the 2021 census baseline is and what analysts derive from it
The 2021 census is the anchor: it recorded 3.9 million Muslims in England and Wales, a 43% rise from 2011 [1]. Analysts in the dataset treat this as a robust starting point and then discuss trends—childhood religious identification, fertility, and migration—that underlie projected increases [6]. The Church of England’s analysis that isolates England’s figures reports about 3.8 million Muslims in England, showing internal consistency across institutional analyses using the same underlying census [2].
4. Demographic drivers highlighted in the materials — why the Muslim share is expected to grow
Multiple pieces in the dataset cite demographic drivers that explain continued growth: higher share of children identifying as Muslim (about 10% of children), higher fertility rates compared with the national average, and migration patterns [6]. These materials stress that a youthful age profile and family formation patterns will push Muslim shares upward even without exceptional migration, which is why commentators discuss projections that see Muslim populations rising through mid-century [5].
5. Projections versus current counts — what the sources say about future shares
The dataset includes projection-focused analysis noting that Muslim shares in Europe and the UK are expected to grow by 2050, but that those are long-range scenarios rather than precise short-term headcounts [5]. The articles link present census increases to projected future growth, yet none of the provided items offers a concrete, independently validated 2025 census-style count. That means 2025 “current” figures in the dataset are best understood as extrapolations from 2021 census data rather than a fresh enumeration [1] [3].
6. Reconciling the available numbers into a cautious 2025 answer
Given the dataset, the most defensible 2025 statement is that the Muslim population in England is around 3.8–3.9 million, and UK-wide or postcensal estimates may push that “over 4 million” if Wales is included or if demographic growth since 2021 is fully counted [2] [3]. The materials do not supply a new official 2025 census figure; therefore the 2021 census baseline plus reasonable demographic growth yields the reported range rather than a single authoritative 2025 headcount [1].
7. What to watch next — where a definitive 2025 figure would come from and why differences matter
A definitive update would come from official ONS mid-year population estimates or a new release explicitly reporting religion post-2021; until then, analysts will rely on extrapolations from the 2021 census and administrative data. The dataset underscores that scope (England vs England and Wales vs UK), rounding, and projection methods drive publicized differences, and these distinctions matter for policy, service planning, and public debate [6] [3]. Check ONS releases and government demographic briefings for any formal 2025 religion-by-area updates.
