Bird's-eye View Of Paris, France

• Density
Paris is one of the most densely populated cities in the world. Its density, excluding the outlying woodland parks of Boulogne and Vincennes, was 24,448 inhabitants per square kilometre (63,320/sq mi) in the 1999 official census, which could be compared only with some Asian megapolis. Even including the two woodland areas, its population density was 20,164 inhabitants per square kilometre (52,224.5/sq mi), the fifth-most-densely populated commune in France following Le Pré-Saint-Gervais, Vincennes, Levallois-Perret, and Saint-Mandé, all of which border the city proper. The most sparsely populated quarters are the western and central office and administration-focussed arrondissements. The city's population is densest in the northern and eastern arrondissements; the 11th arrondissement had a density of 40,672 inhabitants per square kilometre (105,340/sq mi) in 1999, and some of the same arrondissement's eastern quarters had densities close to 100,000/km² (260,000/sq mi) in the same year.
• Paris agglomeration
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.
