According to a survey held in 2016 by Institut Montaigne and Institut français d'opinion publique (IFOP), 51.1% of the total population of France was Christian, 39.6% had no religion (atheism or agnosticism), 5.6% were Muslims, 2.5% were followers of other faiths, and the remaining 0.4% were undecided about their faith. Estimates of the number of Muslims in France vary widely. In 2003, the French Ministry of the Interior estimated the total number of people of Muslim background to be between 5 and 6 million (8–10%). The current Jewish community in France is the largest in Europe and the third-largest in the world after Israel and the United States, ranging between 480,000 and 600,000, about 0.8% of the population as of 2016.
