What are current birth rates among UK Muslims compared with non-Muslim populations?
This fact-check may be outdated. Consider refreshing it to get the most current information.
Executive summary
UK Muslims have historically had higher fertility than the non‑Muslim population, driven largely by younger age profiles and higher birth rates among Pakistani and Bangladeshi-origin women, but those birth rates are falling and the Muslim share of children is rising mainly because Muslims are younger and include many UK‑born families (sources: [1], [3], p1_s4). Available sources do not provide a single current numeric Total Fertility Rate (TFR) comparison for Muslims vs non‑Muslims in 2024–25; past analyses show elevated fertility among Muslim groups especially in early 2000s–2010s but with clear signs of convergence [1] [2].
1. Fertility differences exist but are narrowing — young demography drives the headlines
Studies and commentators cited by demographers show Muslim women in the UK have had higher fertility than the general population, notably because Pakistani and Bangladeshi women — who made up a majority of Muslim women of childbearing age in some past analyses — recorded the highest fertility rates in the 2000s [1]. Media and advocacy pieces point out that the proportion of Muslims among very young children is substantially higher than in the adult population, reflecting both higher birth rates and a younger age profile among Muslims [3] [4]. At the same time, analysts warn that fertility among Muslim immigrant groups has been falling, reducing the gap with the native population [2] [3].
2. Sources stress migration and age structure as the main drivers — not an immutable “Muslim birth rate”
Multiple sources emphasise that growth in the Muslim population is the product of immigration, a younger age profile and historically higher fertility, rather than a single unchanging cultural rate [5] [4]. The Muslim Council of Britain’s census analysis highlights that almost half the Muslim population is UK‑born, and the community is ethnically diverse — factors that affect fertility patterns and make simple comparisons misleading [4]. Channel 4’s factcheck and demographic research note that immigrant fertility often falls over time and that projecting current rates into the distant future overstates likely change [2].
3. Evidence of decline in Muslim fertility — European and UK signals
Demographers and commentators cited by Channel 4 and other analysts report that while Muslim fertility used to be “significantly higher,” birth rates among Muslim immigrant populations in Europe and Muslim‑majority countries are now dropping, which undermines claims that Muslim fertility will perpetually outpace non‑Muslim fertility [2]. DawahSkills and related reporting observe that Pakistani and Bangladeshi-origin birth rates remain relatively high but are falling, contributing to a larger share of young children in the Muslim population while overall fertility converges [3].
4. Data gaps and methodological caveats — why exact comparisons are elusive
Academic work on fertility and religion in the UK stresses methodological challenges: religious identity intersects with ethnicity, immigration timing, and age structure, and routine statistics often rely on inter‑censal estimates or the “own‑child” method rather than straightforward TFRs by religion [1]. The Channel 4 factcheck warns that total fertility rate (TFR) can overestimate lifetime fertility for recent immigrants, because migrants tend to have children soon after arrival; thus headline projections without these adjustments are unreliable [2].
5. What the numbers that are available say — younger Muslim population, higher share of children
Census‑based and community reports document that Muslims make a disproportionately large share of Britain’s under‑fives and that the Muslim population in England and Wales is younger on average than the wider population, factors that amplify the impact of existing birth rates on demographic composition even as fertility rates decline [3] [4]. Wikipedia’s recent summary likewise records consistent growth since World War II and credits recent immigration and a historically higher birth rate among Muslims among the causes [5].
6. Competing framings and political implications — beware alarmist narratives
Media and public debates sometimes use fertility statistics to project dramatic future demographic change; Channel 4’s factcheck cautions that such projections rest on contestable assumptions and may feed alarmism [2]. Community groups and some academics highlight falling fertility and higher UK birth‑origin proportions to counter simplistic narratives that treat Muslim population change as monolithic [3] [4]. Readers should note the implicit agendas: political actors may inflate long‑term projections to stoke concern, while community advocates may emphasise integration and convergence.
Limitations: available sources supplied here do not include a single up‑to‑date numeric TFR comparison for UK Muslims versus non‑Muslims for 2024–25; the picture rests on census analyses, academic estimates and media factchecks that emphasise trends [1] [2] [4].
