Sini, a hill village in the Marmilla

In the interior of the province of Oristano, the Marmilla is an area of gentle hills, open farmland and small villages a short distance apart. Sini is one of them, a compact farming village with the low houses typical of rural Sardinia and fields all around.

Buyers here usually want peace, space and a house with a courtyard. Traditional Sardinian houses, with a gateway on the street and an inner courtyard, have thick walls that keep them cool in summer but suffer from rising damp: check the plaster, the clay-tile roof and the services. The climate, in zone C, is mild. For secondary schools, hospital care and offices people go to Oristano or the larger towns in the area, so a car is essential.

In 2023 there were 494 residents, down 4.1% on 2011, according to Istat, the national statistics office. The average age is 52.6, against 49.8 for the province, and over-65s make up 37.4%. Foreign residents account for 14.0%. Declared incomes are below the provincial average.

Sardinia is quiet when it comes to earthquakes: all 87 municipalities in the province of Oristano are in seismic zone 4, the lowest on the Civil Protection department's national scale, and the expected ground acceleration in Sini is about 0.050 g. In an old house the money is better spent on the roof, damp and insulation.

The Revenue Agency (Agenzia delle Entrate) cadastral maps cover the municipality and the report goes from the address to the land parcel. The report also measures the distance from the house to the pharmacy, shops and schools, and checks the official landslide and flood maps for that spot.

Key points

  • Farming village in the Marmilla, inland Oristano province.
  • All 87 municipalities in the province in seismic zone 4.

Overview

Sini is a municipality in the province of Oristano, in Sardegna. At the end of 2023 it had 494 residents, ranked 55 of 87 municipalities in the province.

Earthquakes

For Italy's Civil Protection Department, Sini is in seismic zone 4, the lowest-risk zone, where strong earthquakes are very rare. All 87 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 4.1%. The estimated average age is 53 years, higher than the province average (50). 37% of residents are over 65 (the regional figure is 27%). Foreign residents make up 14.0% of the population. On average, a household has 2.3 members.

Income and climate

In tax year 2024, taxpayers in Sini declared an average taxable income of 15,589 euros, below the provincial average (19,764 euros). The Italian average is 24,895 euros.

Sini is in climate zone C, with 1,303 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 255 metres above sea level.

How built-up it is

Radon and contaminated sites

Sini 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 low. 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 Sini: 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 Sini are public: from the address the report finds the sheet and parcel number.
