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.
Paris
The official estimated population of the city of Paris was 2,206,488 as of January 1, 2019, according to INSEE, the official French statistical agency. This is a decline of 59,648 from 2015, close to the total population of the 5th arrondissement. Despite the drop, Paris remains the most densely-populated city in Europe, with 252 residents per hectare, not counting parks. This drop was attributed partly to a lower birth rate, to the departure of middle-class residents. and partly to the possible loss of housing in the city due to short-term rentals for tourism.
Paris is the core of a built-up area that extends well beyond its limits: commonly referred to as the "agglomération Parisienne", and statistically as a "unité urbaine" (a measure of urban area), the Paris agglomeration's 2013 population of 10,601,122 made it the largest urban area in the European Union. City-influenced commuter activity reaches well beyond even this in a statistical "aire urbaine" de Paris (a measure of metropolitan area), that had a 2013 population of 12,405,426, a number one-fifth the population of France, the largest metropolitan area in the Eurozone.
