A new report forecasts that the number of Muslims around the world will grow over the next 20 years at twice the rate of non-Muslims, but that the rapid growth will level off.

The world’s Muslim population will grow at double the rate of non-Muslims over the next 20 years, according to a broad new demographic analysis that is likely to spark controversy in Europe and the United States.

Economist: A waxing crescent: Islam is growing. But ageing and slowing. That will change the world

Are Muslims taking over the world, or at a minimum, transforming Europe into Eurabia? Whatever your hopes or fears for the future of the world’s religions, a report published this week has plenty to stoke them. “The Future of the Global Muslim Population”, produced by the Pew Research Centre, a non-profit outfit based in Washington, DC, reckons Muslim numbers will soar from 1.6 billion in 2010 to 2.2 billion by 2030. In other words, from 23.4% to 26.4% of the global total.

Slate: Crowded, with a chance of overcrowded

The global Muslim population will grow twice as fast as the non-Muslim population over the next 20 years, according to a report from the Pew Research Center and the John Templeton Foundation published on Thursday. During the same time period, the American Muslim population will more than double. How do demographers come up with these numbers?

Reuters: Will Pew Muslim birth rate study finally silence the “Eurabia” claim?

One of the most wrong-headed arguments in the debate about Muslims in Europe is the shrill “Eurabia” claim that high birth rates and immigration will make Muslims the majority on the continent within a few decades. Based on sleight-of-hand statistics, this scaremongering (as The Economist called it back in 2006) paints a picture of a triumphant Islam dominating a Europe that has lost its Christian roots and is blind to its looming cultural demise.
