Of course, demographics is not an exact science: Much depends on assumptions about age profiles, standards of living, inequality, and so on, and sooner or later the Muslim fertility rate will converge with the national average. But by then the Muslim population will have expanded rapidly – to 10-20% of the total in the UK.
大量欧洲地区都面临着同样的人口趋势。当然，人口学不属于精确科学：很大程度上要取决于关于年龄结构、生活水平、不平等性等因素的假设，而穆斯林生育率迟早会向全国平均水平靠拢。但那时穆斯林人口已有快速增长——可能占英国总人口的10—20%。这一变化有什么后果是一个有趣的问题。
