Gergei, a farming village in inland Sardinia

Gergei is a village in the interior of southern Sardinia, in the province of Cagliari, towards the centre of the island, at about 370 metres. The land is made up of hills and plateaus, with pasture, cereal fields, olive groves and Mediterranean scrub; the local economy is still tied to farming and livestock.

The centre has houses of stone and of sun-dried earth bricks, often with a courtyard, and newer homes on the edges. Buyers often find large houses, which may however need work on roofs, walls and systems. Cagliari and larger services are reached by car, a journey to take into account if you plan to work there. The climate zone is C; declared incomes are below the provincial average.

The population is shrinking and ageing: 1,101 residents in 2023, 15.2% fewer than in 2011, an average age of 49.4 against 48.1 for the province, and over-65s at 31.3% against 25.7%. Foreign nationals are very few, at 0.7%.

All 70 municipalities in the province of Cagliari are in seismic zone 4, the lowest class, with an expected ground acceleration of 0.050 g. In earth-brick houses, maintenance is the key: breathable plaster, working gutters and walls kept away from water.

The Revenue Agency (Agenzia delle Entrate) publishes cadastral maps, and the report goes from the address to the land parcel. Slope and landslide hazard on the hillsides, and flooding along watercourses, are read on the official maps for the exact address.

Key points

  • Inland farming village among hills and plateaus.
  • Residents down 15.2% since 2011.
  • All 70 municipalities in the province in seismic zone 4.
  • Over-65s at 31.3%, against 25.7% in the province.

Overview

Gergei is a municipality in the province of Cagliari, in Sardegna. At the end of 2023 it had 1,101 residents, ranked 51 of 70 municipalities in the province.

Earthquakes

For Italy's Civil Protection Department, Gergei 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 15.2%. The estimated average age is 49 years, in line with the province. 31% of residents are over 65 (the regional figure is 27%). Foreign residents make up 0.7% of the population. On average, a household has 2.1 members.

Income and climate

In tax year 2024, taxpayers in Gergei declared an average taxable income of 16,170 euros, below the provincial average (19,085 euros). The Italian average is 24,895 euros.

Gergei is in climate zone C, with 1,357 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 374 metres above sea level.

Public transport

We do not yet have open public transport timetables for this municipality: the report says so explicitly, without inventing distances.

How built-up it is

Buildings, roads, car parks and other sealed surfaces cover 2.3% of the land in Gergei, compared with 3.4% in the region. In 2024 built-up land stayed almost the same.

Radon and contaminated sites

Gergei is not among the radon priority areas designated by the Regione Sardegna in 2022. According to the ISPRA map, the estimated radon emission in the municipality is low. Radon varies from building to building and can only be known by measuring it, especially on ground floors and in basements.

Landslides and flooding

Landslide and flood hazard changes from one street to the next even within Gergei: 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 Gergei 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. Here it is worked out at the centre of each of the 7 inhabited census areas in Gergei. Half of the residents live in areas scoring 68 or more.
