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.
Uprava pariškog urbanog rasta podijeljena je između samoga grada i okolnih departmana: Parizu najbliži prsten tri susjedna departmana, ili petite couronne ("mali prsten") potpuno je zasićen rastom grada, dok je daljni vanjski prsten četiri departmana, grande couronne pokriven urbanizacijom samo u unutarnjim područjima.
