San Basilio, a hill village in southern Sardinia

In the inland hills of southern Sardinia, San Basilio is a small farming village at around 400 metres. Fields, pasture and scrub surround the centre, with a few scattered houses and a web of provincial roads leading to the neighbouring villages and, further away, to Cagliari.

The typical home here is a detached house, often on two floors with a courtyard, built or extended at different times. Stone houses in the old core need watching for damp and roof condition. The climate is zone D, with hot summers and mild but damp winters. Declared incomes are below the provincial average, and the main services, from hospitals to secondary schools, are in the larger towns, so a car is a daily necessity.

There were 1,095 residents in 2023, 14.5% fewer than at the 2011 census (Istat, the national statistics office). The average age is 47.1, just below the provincial 48.1, and 24.7% of residents are over 65. Foreign nationals remain few, at 0.8%.

Earthquake hazard is low: all 70 municipalities in the province are in seismic zone 4, and the expected ground acceleration in San Basilio is 0.050 g. In older houses, the state of the roof and load-bearing walls matters more.

The report checks the official landslide and flood maps for the address, which is most useful near the streams running down from the hills. The Revenue Agency (Agenzia delle Entrate) publishes the cadastral maps, so the address leads straight to the land parcel.

Key points

  • Hill farming village at around 400 metres.
  • Population down 14.5% since 2011, foreign nationals 0.8%.
  • All 70 municipalities in the province in seismic zone 4.

Overview

San Basilio is a municipality in the province of Cagliari, in Sardegna. At the end of 2023 it had 1,095 residents, ranked 53 of 70 municipalities in the province.

Earthquakes

For Italy's Civil Protection Department, San Basilio 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 resident population has fallen by 14.5%. 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 0.8% of the population. On average, a household has 2.3 members.

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 3 inhabited census areas in San Basilio. Half of the residents live in areas scoring 76 or more.
