Bird's-eye View Of Paris, France

The first wave of international migration to Paris started as early as 1820 with the arrivals of German peasants fleeing an agricultural crisis in their homeland. Several waves of immigration followed continuously until today: Italians and central European Jews during the 19th century; Russians after the revolution of 1917 and Armenians fleeing genocide in the Ottoman Empire; colonial citizens during World War I and later; Poles between the two world wars; Spaniards, Italians, Portuguese, and North Africans from the 1950s to the 1970s; North African Jews after the independence of those countries; Africans and Asians since then. The Paris metropolitan region or "aire urbaine" is home to some 1.7 million Muslims of all races making up between 10%–15% of the areas population. According to the North American Jewish Data Bank, an estimated 284,000 Jews also live in Paris and the surrounding Île-de-France region, an area with a population of 11.7 million inhabitants. Paris has historically been a magnet for immigrants, hosting one of the largest concentrations of immigrants in Europe today.
Administration
Paris, its administrative limits unchanged since 1860 (save for the addition of two large parks), is one of a few cities that have not evolved politically with its real demographic growth; this issue is at present being discussed in plans for a "Grand Paris" (Greater Paris) that will extend Paris' administrative limits to embrace much more of its urban tissue.
