Administrative subdivision of Rome
The administrative subdivision of Rome consists of the 15 sub-municipalities (municipi) of Rome's municipality. Originally, the city was divided into 20 sub-municipalities, but the XIV, what is now the Comune di Fiumicino, voted in 1992 to become a full municipality itself and eventually detached from Rome. Then on 11 March 2013 the municipalities were reduced from 19 to 15.
History
Since 1972 the city has been divided into administrative areas, called municipi (singular: municipio), until 2001 named circoscrizioni.
They were created for administrative reasons to increase decentralisation in the city. Each municipio is governed by a president and a council of four members who are elected by its residents every five years. The municipi frequently cross the boundaries of the traditional, non-administrative divisions of the city.
The municipi where originally 20, becoming 19 in 1992 after a referendum and the subsequent separation of Fiumicino (XIX Circoscrizione) into an independent Comune. In 2013 their number has been reduced to 15.
