Perdaxius, plain and low hills of the lower Sulcis

Perdaxius is a small village in the Sulcis area of south-west Sardinia, in a landscape of plain and low hills not far from Carbonia. It lies low, under a hundred metres, and lives on farming and on commuting to the larger towns nearby, where you find the hospital, secondary schools and public offices.

The population is falling and ageing. There were 1,301 residents in 2023, down 11.8% since 2011. The average age is 50.3, almost the same as the 50.6 of the Sulcis Iglesiente province, and over-65s are 30.3%. Foreign residents are 0.4%, a very small share. Declared incomes are slightly below the provincial average.

House hunters mostly find detached homes, often with a courtyard, and rural houses with land. The climate is mild (climate zone C) and heating costs little; the things to watch are damp, roofs and the systems in older houses. Services in the village are few, so for a big shop people drive to nearby towns.

There is little to fear from earthquakes. All 24 municipalities in the province are in seismic zone 4, the lowest, with an expected ground acceleration of 0.050 g.

For a purchase, the paperwork is what to look at. Revenue Agency (Agenzia delle Entrate) cadastral maps are published and the report finds the land parcel from the address; it also checks the official landslide and flood maps, useful near the streams on the plain, and measures distances to services.

Overview

Perdaxius is a municipality in the province of Sulcis Iglesiente, in Sardegna. At the end of 2023 it had 1,301 residents, ranked 19 of 24 municipalities in the province.

Earthquakes

For Italy's Civil Protection Department, Perdaxius is in seismic zone 4, the lowest-risk zone, where strong earthquakes are very rare. All 24 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 11.8%. The estimated average age is 50 years, in line with the province. 30% of residents are over 65 (the regional figure is 27%). Foreign residents make up 0.4% of the population. On average, a household has 2.3 members.
