For example: Via San Simaco 1, Simaxis.

Simaxis, the Tirso plain on the edge of Oristano

Simaxis is a village on the Oristano plain, on the bank of the Tirso, the longest river in Sardinia, a few kilometres from the provincial capital. The land is flat, about twenty metres above sea level, with irrigated fields, orchards and farms. For work, secondary schools and the hospital, people turn to Oristano, a few minutes away by car.

For a buyer, being close to the city is the main advantage: detached houses with courtyards, often roomier than in town, and farmland around the village. The other side of the coin is the river. On an alluvial plain the official flood maps need to be read for the exact address, and the report does this for each plot. The climate zone is C, with mild winters and hot summers.

According to Istat, the Italian national statistics office, there were 2,100 residents in 2023, down 9.1% on 2011. The average age is 49.3, slightly below the 49.8 of the province of Oristano, and over-65s make up 27.2%. Foreign residents account for 1.8%. Declared incomes are close to the provincial average.

Earthquakes are a minor issue here: the whole province is in seismic zone 4, the lowest, with an expected ground acceleration of 0.050 g. In older houses, often built of mud brick or stone, damp and wall maintenance are what matter most.

The Revenue Agency (Agenzia delle Entrate) publishes the cadastral maps, so the report traces the plot from the address and measures distances to services.

Overview

Simaxis is a municipality in the province of Oristano, in Sardegna. At the end of 2023 it had 2,100 residents, ranked 19 of 87 municipalities in the province.

Earthquakes

For Italy's Civil Protection Department, Simaxis 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 9.1%. The estimated average age is 49 years, in line with the province. 27% of residents are over 65 (the regional figure is 27%). Foreign residents make up 1.8% of the population. On average, a household has 2.2 members.

Income and climate

In tax year 2024, taxpayers in Simaxis declared an average taxable income of 19,113 euros, in line with the province (19,764 euros). The Italian average is 24,895 euros.

Simaxis is in climate zone C, with 1,069 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.

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 6.7% of the land in Simaxis, compared with 3.4% in the region. In 2024 built-up land grew by 0.6 hectares.

Radon and contaminated sites

Simaxis is not among the radon priority areas designated by the Regione Sardegna in 2022. 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 Simaxis: 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 Simaxis 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 22 inhabited census areas in Simaxis. Half of the residents live in areas scoring 71 or more.
