.... France, which is home to an estimated six million Muslims, has the largest Muslim population in the European Union. There are now, in fact, more practicing Muslims in France than there are practicing Roman Catholics.
Although 64% of the French population (or 41.6 million of France's 65 million inhabitants) identify themselves as Roman Catholic, only 4.5% (or 1.9 million) of these actually are practicing Catholics, according to a separate survey on Catholicism in France published by Ifop in July 2009.
By way of comparison, 75% (or 4.5 million), of the estimated six million mostly ethnic North African and sub-Saharan Muslims in France, identify themselves as "believers;" and 41% (or 2.5 million) say they are "practicing" Muslims, according to an in-depth research report on Islam in France published by Ifop in July 2011.
