In the same survey, 7 percent of residents identified themselves as Muslims, 4 percent as Protestants, 2 percent as Jewish and 25 percent as without religion.

According to the INSEE, between 4 and 5 million French residents were born, or had at least one parent born, in a predominantly Muslim country, particularly [[Algeria]], [[Morocco]] and [[Tunisia]]. An IFOP survey in 2008 reported that, of immigrants from these predominantly Muslim countries, 25 percent went to the mosque regularly. 41 percent practised the religion, and 34 percent were believers, but did not practice the religion.<ref>{{cite news |url=http://www.lemonde.fr/les-decodeurs/article/2015/01/21/que-pese-l-islam-en-france_4559859_4355770.html |title=que pese l'Islam en France |work=Le Monde |date=21 January 2015 |language=fr |access-date=13 November 2015 |archive-url=https://web.archive.org/web/20151127053220/http://www.lemonde.fr/les-decodeurs/article/2015/01/21/que-pese-l-islam-en-france_4559859_4355770.html |archive-date=27 November 2015 |url-status=live}}</ref><ref>{{cite web |url=http://plus.lefigaro.fr/note/how-does-france-count-its-muslim-population-20110407-435643 |title=How does France count its muslim population? |work=Le Figaro |access-date=30 October 2015 |archive-url=https://web.archive.org/web/20151105002152/http://plus.lefigaro.fr/note/how-does-france-count-its-muslim-population-20110407-435643 |archive-date=5 November 2015 |url-status=live}}</ref> In 2012 and 2013, it was estimated that there were almost 500,000 Muslims in the City of Paris, 1.5 million Muslims in the Île-de-France region and 4 to 5 million Muslims in France.<ref>{{cite web |url=http://archive.francesoir.fr/actualite/societe/dalil-boubakeur-%E2%80%9Cil-faut-doubler-nombre-mosquees-en-france%E2%80%9D-54083.html |archive-url=https://web.archive.org/web/20150128112504/http://archive.francesoir.fr/actualite/societe/dalil-boubakeur-%E2%80%9Cil-faut-doubler-nombre-mosquees-en-france%E2%80%9D-54083.html |url-status=live |archive-date=28 January 2015 |title=Interview with Dalil Boubakeur |work=Le Soir |language=fr |access-date=13 November 2015}}</ref><ref>{{cite news |last1=Riou |first1=Mathilde |title=Le manque de mosquée en Ile-de-France |url=http://france3-regions.francetvinfo.fr/paris-ile-de-france/2013/04/29/le-manque-de-mosquee-en-ile-de-france-243225.html |access-date=17 November 2017 |work=France 3 |date=29 April 2013 |archive-url=https://web.archive.org/web/20171117174949/http://france3-regions.francetvinfo.fr/paris-ile-de-france/2013/04/29/le-manque-de-mosquee-en-ile-de-france-243225.html |archive-date=17 November 2017 |url-status=live}}</ref>
