Bird's-eye View Of Paris, France

The city of Paris covers an area much smaller than the urban area of which it is the core. At present, Paris' real urbanisation, defined by the pôle urbain (urban area) statistical area, covers 2,723 km2 (1,051 sq mi), or an area about 26 times larger than the city itself. The administration of Paris' urban growth is divided between itself and its surrounding départements: Paris' closest ring of three adjoining departments, or petite couronne ("small ring") are fully saturated with urban growth, and the ring of four departments outside of these, the grande couronne départements, are only covered in their inner regions by Paris' urbanisation. These eight départements form the larger administrative Île-de-France région; most of this region is filled, and overextended in places, by the Paris aire urbaine.
The Paris agglomeration has shown a steady rate of growth since the end of the late 16th century French Wars of Religion, save brief setbacks during the French Revolution and World War II. Suburban development has accelerated in recent years: With an estimated total of 11.4 million inhabitants for 2005, the Île-de-France région shows a rate of growth double that of the 1990s.
• Immigration
By law, French censuses do not ask questions regarding ethnicity or religion, but do gather information concerning one's country of birth. From this it is still possible to determine that Paris and its aire urbaine (metropolitan area) is one of the most multi-cultural in Europe: At the 1999 census, 19.4% of its total population was born outside of metropolitan France. At the same census, 4.2% of the Paris aire urbaine's population were recent immigrants (people who had immigrated to France between 1990 and 1999), in their majority from Asia and Africa. 37% of all immigrants in France live in the Paris region.
