Administrative subdivision of Rome

On 31 March 1966, for administrative purposes and to increase decentralization, the territory of the comune of Rome was divided into 12 administrative areas, called circoscrizioni (singular: circoscrizione). On 11 February 1972 those areas were increased to 20.

On 6 March 1992, after the referendum that ratified the separation of the then Circoscrizione XIV from Rome and the birth of the new independent comune of Fiumicino, the number of administrative areas of Rome decreased to 19.

On 19 January 2001, circoscrizioni which were renamed municipi and the direct election of a President to head each municipio wa established.[1]

On 11 March 2013, Rome City Council decided to merge some of the municipi, reducing their number to 15 and giving them a new numeration.[2]

The comune of Rome is also composed of 155 urban zones (zone urbanistiche), conceived as a subdivision of the municipi, which were established in 1977 for statistical and city planning purposes on the basis of urban homogeneity criteria. Boundaries were drafted taking account of the discontinuities in Rome's urban pattern The urban zones are identified by an alphanumeric code that consists of a letter and of the number of the municipio where the zone was located: indeed, the municipi were reduced from 20 to 15 in 2013, but the alphanumeric codes were not revised.

  quartieri (neighborhoods)

  suburbi (suburbs)

  zone dell'Agro romano (areas of Agro romano)

Rome is also divided into 116 non-administrative units, called comprensori toponomastici (toponymic districts), which are organized into four groups:

• 22 rioni located in the historic centre of the city, mostly within the Aurelian Walls, except for Prati and Borgo;
• 35 quartieri surrounding the historic centre of Rome outside the Aurelian Walls;
• 6 suburbi located in the suburban area of the city;
• 53 zone in the countryside of the comune.

The rioni originate from the Regiones of ancient Rome, which evolved in the Middle Ages into the medieval rioni.[3] In the Renaissance, under Pope Sixtus V, they reached again the number of fourteen, and their boundaries were finally defined under Pope Benedict XIV in 1743.

A new subdivision of the city under Napoleon was ephemeral, and there were no sensible changes in the organisation of the city until 1870 when Rome became the capital of Italy. The needs of the new capital led to an explosion both in the urbanisation and in the population within and outside the Aurelian Walls. In 1874 a fifteenth rione, Esquilino, was created on the newly urbanised zone of Monti. At the beginning of the 20th century other rioni where created (the last one was Prati – the only one outside the Walls of Pope Urban VIII – in 1921). Afterward, for the new administrative subdivisions of the city the name "quartiere" was used. Today all the rioni are part of the first Municipio, which therefore coincides completely with the historical city (Centro Storico).
