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.
Communauté urbaine
As of April 2018, there are 11 communautés urbaines in France (all in metropolitan France), with a combined population of 2.43 million inhabitants (as of 2015, in 2018 limits). All of the urban areas in France with more than half a million inhabitants are a communauté urbaine or a métropole. Some communautés urbaines are relatively small; smaller than many communautés d'agglomération.
