Settimo San Pietro, young families on the edge of Cagliari
Settimo San Pietro is one of the towns around Cagliari that have taken in families leaving the city for bigger, cheaper homes over recent decades. It lies on the Campidano plain north-east of the regional capital, between Selargius and Sinnai, at around seventy metres, with the first hills rising to the east.
The old centre still has traditional Campidano courtyard houses, built around an inner yard, often with walls of sun-dried earth bricks. They are spacious homes, but buyers need to check damp, roofs and the condition of the walls carefully, because earth brick needs suitable materials and methods when it is restored. Newer detached and terraced houses have been added all around. People working in Cagliari almost always drive, and at rush hour the roads into the city get busy.
The population is growing. Istat, the national statistics office, counted 6,963 residents in 2023, up 6.6% on the 6,532 of 2011. It is a young town by Sardinian standards, with an average age of 45.2 against 48.1 for the province and 21.0% over 65. Foreign residents are just 1.0%. Declared incomes are below the provincial average, which is lifted by Cagliari itself. There are 6 supermarkets, more per head than average, but few cafés and restaurants.
Earthquake hazard is the lowest in Italy: the Civil Protection Department places all of Sardinia in seismic zone 4, and the expected ground acceleration here is about 0.050 g. For a house on sale, build quality, protection from summer heat and the state of the wiring and plumbing matter more.
In the low-lying areas crossed by streams running down from the hills, autumn downpours can cause water problems, and the report checks flood hazard for the exact address. The Revenue Agency (Agenzia delle Entrate) publishes cadastral maps, so an address can be traced to its land parcel.

Earthquakes
For Italy's Civil Protection Department, Settimo San Pietro 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.
