The report looks at the exact point: landslide and flood risk, seismic zone, price per square metre for the area, services and nearby stops.

For example: Via Giovanni Pascoli 1, Senorbì.

Senorbì, the hub of the Trexenta

The Trexenta is an area of low clay hills north of Cagliari, farmed for centuries for wheat, and Senorbì is its main town: people come here from all the surrounding villages for schools, shops, offices and clinics. Cagliari is about 45 minutes away along the main road heading into the centre of Sardinia.

Its role as a small service centre shows in the data. The town has 8 supermarkets, 1.67 per 1,000 residents against 0.65 in the province, 6 schools and 7 sports facilities, all above average. Buyers will find traditional courtyard houses built of mud brick or stone in the centre, and newer houses on the edges. The town's archaeological museum holds finds from the local necropolis and nuraghi, the Bronze Age stone towers typical of Sardinia.

The population is steady. Istat, the national statistics office, recorded 4,793 residents in 2023, up 0.3% on 2011, while many nearby villages are losing people. The average age is 46.2, below the province (48.1), and 22.6% are over 65. Declared incomes are in line with the provincial average.

Earthquakes are almost absent in Sardinia. All 70 municipalities in the province are in seismic zone 4, the lowest in the Civil Protection Department classification, and expected ground acceleration here is about 0.050 g. In mud-brick houses, typical of the Campidano and Trexenta, what matters is damp at the base of the walls and the state of the plaster.

The climate is mild (climate zone C), with hot, dry summers. On the clay soils the report checks landslides and spots where water collects after storms at the address, and uses the Revenue Agency cadastre to find the plot.

Key points

  • Main town of the Trexenta, wheat hills north of Cagliari.
  • 8 supermarkets and 6 schools, above average.
  • 4,793 residents, steady since 2011.
  • Seismic zone 4, like the whole province.

Overview

Senorbì is a municipality in the province of Cagliari, in Sardegna. At the end of 2023 it had 4,793 residents, ranked 21 of 70 municipalities in the province.

Earthquakes

For Italy's Civil Protection Department, Senorbì is in seismic zone 4, the lowest-risk zone, where strong earthquakes are very rare. All 70 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 number of residents is nearly unchanged. The estimated average age is 46 years, lower than the province average (48). 23% of residents are over 65 (the regional figure is 27%). Foreign residents make up 3.2% of the population. On average, a household has 2.3 members.

Income and climate

In tax year 2024, taxpayers in Senorbì declared an average taxable income of 19,088 euros, in line with the province (19,085 euros). The Italian average is 24,895 euros.

Senorbì is in climate zone C, with 1,215 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 204 metres above sea level.

Services

Landslides and flooding

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