Executive summary

No — Britain has not been "overtaken" by Muslims; Muslims make up a growing but still modest share of the population (about 6.5% or 3.9 million in 2021) and projections show possible increases under some scenarios, not an immediate or inevitable takeover [1] [2] [3].

1. What “overtaken” would mean — population, power, or culture?

The claim needs unpacking: if “overtaken” means numerical majority, current data show Muslims are a minority at roughly 6.5% of England and Wales and about 3.9 million people in the 2021 census, so Britain is far from a Muslim-majority nation today [1] [2]; if it means rapid growth or greater public visibility, official censuses and analyses document faster growth rates for Muslim populations in recent decades, driven by younger age structures, higher birth rates historically, and migration [4] [2].

2. The numbers: steady growth, not a sudden takeover

Census data and reporting indicate the Muslim population rose by around 44% in a decade to 3.9 million in 2021, making Islam the second-largest religion in England and Wales, but still a minority of the total population [1] [2]. Long-term projections vary: one data aggregator notes a scenario in which the UK Muslim share could rise to 17.2% by 2050, but projections are scenario‑based and depend heavily on future migration, fertility convergence, and age-structure assumptions — not deterministic certainties [3] [2].

3. Why growth has been faster than average

Analysts point to demographic factors: the British Muslim population is younger on average, with a higher proportion in childbearing ages, and migration historically contributed substantially to increases — these structural features explain faster growth without implying sudden takeover dynamics [2] [5]. Channel 4’s factcheck cautions that past higher fertility among Muslim populations is trending down and that identification on censuses can change over time, complicating headline projections [6].

4. Geography and social realities: concentrated, diverse, and unequal

Muslim communities are unevenly distributed — some towns and cities (for example Bradford and Oldham are noted for sizable Muslim populations and large mosques) have much higher concentrations than the national average, which can create local perceptions of being “overtaken” even while nationwide figures remain far lower [3]. The Muslim Council of Britain’s census summary emphasizes internal diversity and socioeconomic challenges: significant shares of Muslims live in more deprived areas and face persistent inequalities, which is an important part of the picture that raw population percentages don’t capture [7].

5. Projections, conversions, and the limits of forecasting

Conversion plays a smaller role in overall growth than demographic and migration trends; some sources estimate conversions in Britain number in the low thousands per year, but migration and age structure have been more important drivers [5] [2]. Projected numbers for mid-century vary widely across models — they are scenario-based, not guaranteed outcomes, and Channel 4 warns that simple extrapolations to a Muslim majority by 2050 ignore likely changes in fertility, migration, and identity reporting [3] [6].

6. Competing narratives and political uses of the claim

The simple “overtaken” framing is politically charged and often used to stoke fear or amplify a sense of cultural threat; careful reading of the sources shows growth but not numerical dominance, and highlights socioeconomic challenges rather than cultural conquest [7] [6]. Different outlets and commentators emphasize different parts of the story — raw percentage growth, local concentrations, or long‑range projections — so readers should be alert to agendas that treat projections as certainties [3] [6].

7. Bottom line

Available official counts and reputable analyses show Muslims are a growing minority in Britain with notable local concentrations and structural inequalities, but there is no evidence Britain has been or imminently will be “overtaken” by Muslims; long‑range scenarios project increases under certain assumptions, not an unavoidable takeover [1] [2] [3] [6].
