Demographics of France
According to Michel Tribalat, a researcher at INED, there were 3.5 million people of Maghrebi origin (with at least one grandparent from Algeria, Morocco or Tunisia) living in France in 2005 corresponding to 5.8% of the total French metropolitan population (60.7 million in 2005). Maghrebis have settled mainly in the industrial regions in France, especially in the Paris region. Many famous French people like Edith Piaf, Isabelle Adjani, Arnaud Montebourg, Alain Bashung, Dany Boon and many others have Maghrebi ancestry.

According to a survey held by Institut français d'opinion publique (Ifop) for the Institut Montaigne think-tank, 51.1% of the total population of France was Christian in 2016. The following year, a survey by Ipsos focused on Protestants and based on 31,155 interviews found that 57.5% of the total population of France declared to be Catholic and 3.1% declared to be Protestant.
