Naples, between Vesuvius and the Campi Flegrei

Naples (Napoli) spreads around its bay between two volcanic areas, Vesuvius to the east and the Campi Flegrei (Phlegraean Fields) to the west. Founded by the Greeks as Neapolis, it has a UNESCO-listed historic centre and a port with connections to the islands of the bay and to other Mediterranean cities.

At the end of 2023 it had 913,704 residents, 30.8% of the metropolitan city, with an estimated average age of 44.4 (43.2 across the metropolitan city) and 22.0% of residents over 65. Households average 2.41 people, and foreign residents make up 6.4%. The population has, however, fallen by 5.0% since the 2011 census.

Under the national seismic classification Naples is in zone 2, like 76 of the 92 municipalities in the metropolitan city; the other 16 are in zone 3. The expected ground acceleration in the built-up area is about 0.167 g, a medium-high value. Earthquakes are not the only ground-related issue here, though: parts of the municipality fall within the areas covered by the Civil Protection emergency plans for Vesuvius and for the Campi Flegrei. The report does not replace those plans, which can be consulted on the website of Italy's Civil Protection Department (Dipartimento della Protezione Civile) for the area you are interested in.

For everyday services, the Ministry of Health lists 318 pharmacies, 0.35 per 1,000 residents, slightly above the metropolitan average of 0.31. Overture Maps data record 420 supermarkets, less dense than in the rest of the metropolitan area (0.46 against 0.58 per 1,000), and 4,459 cafés, bars and restaurants.

The Revenue Agency (Agenzia delle Entrate) publishes cadastral maps for Naples as well, so the report can trace an address to its sheet and parcel (foglio and particella). In a city of hills, coastline and very different districts, landslide and flood hazard and the price range are checked for each individual address.

Key points

  • 913,704 residents with an average age of 44.4.
  • Population down 5.0% since 2011.
  • Seismic zone 2; parts of the city lie within the Vesuvius and Campi Flegrei emergency plans.
  • 318 pharmacies, slightly above the metropolitan average per resident.

Overview

Napoli is the capital of the province of Napoli, in Campania. At the end of 2023 it had 913,704 residents, the most populous municipality in the province. 31% of the province's residents live here.

Earthquakes

For Italy's Civil Protection Department, Napoli is in seismic zone 2, a zone where strong earthquakes are possible. Most municipalities in the province (76 of 92) are in the same zone.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.167 g, a medium-high value: the level with a 10% probability of being exceeded in 50 years, on rock.

For anyone buying in Napoli, the building matters a great deal: ask for the design year, whether it met the 2008 seismic standards, and whether any seismic retrofit has been carried out.

Population

Compared with the 2011 census, the resident population has fallen by 5.0%. The estimated average age is 44 years, in line with the province. 22% of residents are over 65 (the regional figure is 21%). Foreign residents make up 6.4% of the population. On average, a household has 2.4 members.

Income and climate

In tax year 2024, taxpayers in Napoli declared an average taxable income of 24,332 euros, above the provincial average (21,545 euros). The Italian average is 24,895 euros.

Napoli is in climate zone C, with 1,034 heating degree days: heating may be switched on from 15 November to 31 March, for up to 10 hours a day. The same table puts the town hall at 17 metres above sea level.

Services

In the official Ministry of Education and Ministry of Health lists, Napoli has 713 schools and 318 pharmacies. The Overture Maps data also lists 420 grocery shops and supermarkets, 759 healthcare facilities, 586 sports facilities and 114 parks and green areas.

There are 0.8 healthcare facilities per 1,000 residents, more than the province average (0.6).

Public transport

We do not yet have open public transport timetables for this municipality: the report says so explicitly, without inventing distances.

How built-up it is

Buildings, roads, car parks and other sealed surfaces cover 63.7% of the land in Napoli, compared with 34.9% in the province and 10.6% in the region. In 2024 built-up land grew by 13.4 hectares.

Radon and contaminated sites

According to the ISPRA map, the estimated radon emission in the municipality is medium. Radon varies from building to building and can only be known by measuring it, especially on ground floors and in basements.

Official databases list 28 contaminated sites, or sites still under investigation, in Napoli, and 22 more have been cleaned up or closed. The report tells you whether one is close to the address.

Landslides and flooding

Landslide and flood hazard changes from one street to the next even within Napoli: the report checks the address against the ISPRA maps.

House prices

The Revenue Agency's price ranges per square metre (OMI) apply to zones, not to whole municipalities: the report gives the range for the address's zone.

Land registry

The cadastral maps for Napoli are public: from the address the report finds the sheet and parcel number.

Liveability area by area

The Vicinalia liveability index runs from 0 to 100 and looks at the place, not the people who live there: services within walking distance, transport, green space, natural hazards, air, quiet, buildings and connection. Here it is worked out at the centre of each of the 4,219 inhabited census areas in Napoli. Half of the residents live in areas scoring 66 or more.

Residents by band
