Ossi, the Coros hills a short drive from Sassari

Ossi is only a few kilometres by road from Sassari, and for many families it works as an extension of the city: they live here and go to Sassari for work, school or the doctor. The town belongs to the Coros, an area of limestone uplands and olive groves south of Sassari, and its centre stands at around 300 metres.

Within the municipality is the Mesu 'e Montes necropolis, a group of domus de janas, the prehistoric rock-cut tombs typical of northern Sardinia. The town has an old core of low stone houses surrounded by districts of two-storey detached homes built over recent decades, often with a yard or small garden. The market is that of a commuter town, cheaper than the city, and you will need a car for almost everything.

At the end of 2023 Ossi had 5,438 residents, down 7.5% since 2011. The average age is 47.5, slightly lower than in the province (48.3), and foreign residents are very few, at 0.9%. Average incomes are below the provincial average.

All 66 municipalities in the province of Sassari are in seismic zone 4, the lowest in the national classification, and the expected ground acceleration is about 0.050 g. In a house a few decades old, check instead for leaks from a flat roof, damp and poor insulation. Winters fall in climate zone D, colder than you might expect if you only know Sardinia's coast.

The valleys cut into the upland have steep sides and small streams. The report checks landslide and flood hazard for the address and uses the Revenue Agency (Agenzia delle Entrate) cadastral maps.

Key points

  • A Coros town a few kilometres from Sassari.
  • The prehistoric Mesu 'e Montes necropolis lies within its bounds.
  • 5,438 residents, foreign residents at 0.9%.
  • Seismic zone 4, like the whole province of Sassari.

Overview

Ossi is a municipality in the province of Sassari, in Sardegna. At the end of 2023 it had 5,438 residents, ranked 9 of 66 municipalities in the province.

Earthquakes

For Italy's Civil Protection Department, Ossi is in seismic zone 4, the lowest-risk zone, where strong earthquakes are very rare. All 66 municipalities in the province are in the same zone.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.050 g, a moderate value: the level with a 10% probability of being exceeded in 50 years, on rock.

In zone 4 the risk is low, but for an older building it is still worth asking about the state of the structure.

Population

Compared with the 2011 census, the resident population has fallen by 7.5%. The estimated average age is 47 years, in line with the province. 25% of residents are over 65 (the regional figure is 27%). Foreign residents make up 0.9% of the population. On average, a household has 2.3 members.

Income and climate

In tax year 2024, taxpayers in Ossi declared an average taxable income of 19,033 euros, below the provincial average (21,361 euros). The Italian average is 24,895 euros.

Ossi is in climate zone D, with 1,528 heating degree days: heating may be switched on from 1 November to 15 April, for up to 12 hours a day. The same table puts the town hall at 322 metres above sea level.

Services

In the official Ministry of Education and Ministry of Health lists, Ossi has 6 schools and 2 pharmacies. The Overture Maps data also lists 3 grocery shops and supermarkets, 2 healthcare facilities, 1 sports facility and 2 parks and green areas.

There are 0.4 healthcare facilities per 1,000 residents, fewer than the province average (0.9).

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 8.4% of the land in Ossi, compared with 3.4% in the region. In 2024 built-up land stayed almost the same.

Radon and contaminated sites

Ossi is not among the radon priority areas designated by the Regione Sardegna in 2022. 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.

Landslides and flooding

Landslide and flood hazard changes from one street to the next even within Ossi: 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 Ossi 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 21 inhabited census areas in Ossi. Half of the residents live in areas scoring 83 or more.
