Even if migration to Europe ceased — no immigrants, no refugees — the percentage of Muslims in those countries would still rise over the next three decades.
That's according to new projections released Wednesday (Nov. 29) by the Pew Research Center.
Though it hasn't been long since Pew made its last projections on population growth of world religions, which were based on 2010 numbers, a record number of asylum seekers from Syria and other predominantly Muslim countries has changed the picture considerably.
As of mid-2016, Muslims make up nearly 5 percent of the population in the 28 countries of the European Union, plus Norway and Switzerland, according to the new Pew report. That's an estimated 25.8 million people.
