The recent terrorist attacks in Paris have brought new attention to the small number of European Muslims who turn to violent extremism. Fears center around the number of Europeans who have fought in Iraq and Syria and could return to the continent. Amid tensions over terrorism and intolerance in France, the Muslim population there is projected to grow steadily in the coming years in comparison to non-Muslim populations and in many other European counties. Demographic changes, including lower birthrates for non-Muslim Europeans, are contributing to the changing face of Europe’s religious and ethnic make-up. The above map shows historical data and projections for the growth of Muslim populations in Europe in 2030.
