The administration of Paris's urban growth is divided between itself and its surrounding departments: Paris's 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 departments, are only covered in their inner regions by Paris's urbanisation.
Administrasi pertumbuhan urban Paris terbagi antara kota itu dan département sekitarnya: lingkaran terdekat Paris yang berisi tiga departemen bersebelahan, atau petite couronne ("lingkaran kecil") dipengaruhi pertumbuhan urban, dan lingkaran berisi empat departemen di luarnya, département grande couronne, hanya mencakup region dalamnya oleh urbanisasi Paris.
