What percentage of the UK population identifies as Muslim according to the 2025 census?

1. What the available sources actually report about Muslims and the census

The documents and articles you supplied do not include a 2025 nationwide UK census result giving a new Muslim share of the population. The Muslim Council of Britain’s "British Muslims in Numbers: Census Report Summary 2025" and its PDF summary both draw on the 2021 Census outputs rather than a new 2025 enumeration and present findings such as patterns of deprivation and household composition based on 2021 data ^{[2] [3]}. The Wikipedia entry cited likewise reports the 2021 Census figure of just under four million Muslims — about 6.0% of the UK population — as the recognised baseline from that census ^[1].

2. Why some outlets talk about 2025 while using 2021 data

The Muslim Council of Britain’s materials are dated 2025 but explicitly say they "draw on the 2021 census data provided by the Office of National Statistics" for England & Wales and other national statistics agencies for Scotland and Northern Ireland, meaning 2025 publications can summarise or reinterpret older census outputs rather than report a new national headcount ^[3]. That explains headlines or summaries published in 2025 that discuss "census" patterns without offering a new 2025 percentage figure ^{[2] [3]}.

3. The best-number available in these sources: 6.0% from 2021

The clearest numerical claim in the supplied material is the widely cited 2021 Census result: "just under four million" Muslims or roughly 6.0% of the United Kingdom’s total population, which is reported in the Wikipedia summary and echoed in census-based analyses ^[1]. The ONS and devolved statistics bodies produced the 2021/2022 census outputs that underpin these figures; the MCB documents rely on those same datasets ^{[3] [4]}.

4. Limits of the supplied reporting and what’s not found

The supplied search results do not include an official "2025 census" result for the UK giving a different Muslim share. There is no ONS/ONS-partner release in these results that updates the national Muslim percentage for 2025, and the ONS freedom-of-information-style page provided discusses methodology and availability of variables rather than a 2025 percentage ^[4]. Therefore, any claim that a 2025 census established a new UK-wide percentage for Muslims is not supported by these documents — available sources do not mention a 2025 census percentage for Muslims ^{[4] [3]}.

5. Competing interpretations and common pitfalls in coverage

Some outlets or organisations publish 2025 analyses or summaries that reuse 2021 census data; this can create the impression of fresher measurement than exists ^{[2] [3]}. Secondary sites (for example, a news or religious outlet republishing census commentary) may report demographic shifts or trends and attach a 2025 dateline even when the underlying numbers are from 2021 ^{[1] [2]}. Readers should check whether a story cites "2021 Census" or an actual new enumeration before accepting "2025 census" claims ^{[3] [4]}.

6. Bottom line and how to verify further

Based on the provided materials, the most defensible figure is the 2021 Census estimate of roughly 6.0% of the UK population identifying as Muslim ^[1]. If you need an official 2025 figure, consult primary statistics releases from the Office for National Statistics, National Records of Scotland, and the Northern Ireland Statistics & Research Agency; those authorities and the MCB materials indicate the distinction between 2021 census outputs and later analyses ^{[4] [3]}. Available sources do not mention a completed UK-wide 2025 census percentage for Muslims ^{[4] [3]}.
