Collinas, a village in the low hills of Marmilla

In Marmilla, the area of gentle hills and open fields between the Campidano plain and the interior of Sardinia, Collinas is a compact village at around 250 metres. The surrounding landscape is arable land, grazing and small rises, with roads linking the village to the other centres nearby and, further off, to the plain and the main road towards Cagliari and Oristano.

The population has fallen considerably. Istat, the national statistics office, counted 885 residents in 2011 and 755 in 2023: 130 fewer, a drop of 14.7%. The average age is 52.9, against 49.4 in the province of Medio Campidano, and over-65s make up 35.8%, more than the provincial 28.9%. There are few foreign residents, 1.2%. Average declared income is also below the provincial figure.

What comes up for sale is mostly village houses, in the older buildings often of stone or sun-dried mud brick, with an inner courtyard. In houses like these, check rising damp, the roof and the wiring and plumbing, and find out whether recent work was done with the proper permits. This is climate zone C: mild winters and hot, dry summers, so shade and insulation matter as much as heating.

Earthquakes are a minor concern. All 28 municipalities in Medio Campidano are in seismic zone 4, the lowest class, and the expected ground acceleration in Collinas is about 0.050 g.

The Revenue Agency (Agenzia delle Entrate) publishes the cadastral maps for the municipality and the report links each address to its land parcel. Flooding along the streams and the slope of the ground are checked on the official maps for the individual plot.

Key points

Overview

Collinas is a municipality in the province of Medio Campidano, in Sardegna. At the end of 2023 it had 755 residents, ranked 20 of 28 municipalities in the province.

Earthquakes

For Italy's Civil Protection Department, Collinas is in seismic zone 4, the lowest-risk zone, where strong earthquakes are very rare. All 28 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.

The estimated average age is 53 years, higher than the province average (49). 36% of residents are over 65 (the regional figure is 27%). Foreign residents make up 1.2% of the population. On average, a household has 2.1 members.
