Siris, a small and steady village in the Marmilla

Many small villages in inland Sardinia have been losing people for years; Siris has held steady. According to Istat, Italy's national statistics office, there were 228 residents in 2023, against 224 at the 2011 census, a rise of 1.8%. With numbers this small a few families can tip the balance either way, but the figure still goes against the trend.

Age tells a slightly different story from the usual one too. The estimated average age is 49.7, practically the same as the 49.8 of the province of Oristano, and over-65s make up 31.1%. Households have 2.35 members on average. Declared incomes, on the other hand, are well below the provincial average.

The village sits on low hills, a little over a hundred and fifty metres up, in a farming area of the interior. Winters are mild and summers hot. Services, offices and the hospital are in Oristano or the larger towns of the area, and you need a car for almost everything. Houses are mostly low, on one or two floors: before buying, check the roof, rising damp and whether the wiring and plumbing are up to standard, and ask whether any extensions were built with planning permission.

Earthquake risk is low. Siris, like all 87 municipalities in the province, is in seismic zone 4 on the Civil Protection Department's scale, with an expected ground acceleration of about 0.050 g. The Revenue Agency (Agenzia delle Entrate) publishes cadastral maps here, and the report goes from the address to the land parcel, with the official flood and landslide maps and distances to services.

Overview

Siris is a municipality in the province of Oristano, in Sardegna. At the end of 2023 it had 228 residents, among the smallest in the province (78 of 87).

Earthquakes

For Italy's Civil Protection Department, Siris 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 grown by 1.8%. The estimated average age is 50 years, in line with the province. 31% of residents are over 65 (the regional figure is 27%). Foreign residents make up 0.9% of the population. On average, a household has 2.4 members.

Income and climate

Public transport

How built-up it is

Radon and contaminated sites

Siris 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.

Landslide and flood hazard changes from one street to the next even within Siris: 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.
