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.
Immigration to France
The region with the largest proportion of immigrants is the Île-de-France (Greater Paris), where 40% of immigrants live. According to INSEE, French National Institute for Statistics and Economic Studies, responsible for the production and analysis of official statistics in France, about 35% of people (4 millions) living in Île-de-France, are either immigrant (17%) or born to at least one immigrant parent (18%) in 2006.
