Why the fear of Islamization is driving populist right support, and what to do about it

.... The belief that Muslims have sky-high fertility and will take over Europe is not confined to viral videos with over 16m views. At the European Commission, I was astounded to hear a member of the European elite ask whether such claims were true. The extent of this demographic illiteracy makes it imperative to begin a concerted public information campaign.

Figure 1 shows that no country will be more than 10 percent Muslim in 2030. So in 2050, France is projected to be just 10.4 percent Muslim. Yet Ipsos-Mori’s report shows the average French person thinks France will be 40 percent Muslim in 2020, instead of the actual 8 percent.

Across Europe, the average overestimate of 2020 Muslim share is 25 points. Previous work by Bobby Duffy and Tom Frere-Smith at Ipsos-Mori shows that people across the West routinely overestimate immigrant share by a factor of two or three.

But information can counteract these claims. A recent survey experiment finds that when people are given accurate information about the share of foreign born in their country then asked a month later what the share is, they adjust their estimates 12 points closer to reality.

The Pew projections, based on the best immigration, fertility, and switching data we have, show that the rate of Muslim growth in Europe is tapering. In 2050, no West European country will be more than 12.4 per cent Muslim, far lower than most think is the case today. [British Politics and Policy blog] Read more
