Maretto, a small municipality in the hills around Asti

Maretto is one of the small municipalities in the hills around Asti: a village of a few hundred people, houses scattered along the ridges and farmland all around, at about 240 metres. Asti is the place people rely on for work, secondary schools, hospital care and trains, reached by car.

The figures describe a village younger than the provincial average. The estimated average age is 46.6, below the provincial 47.9, and over-65s make up 21.3% against 27.3% across the province of Asti. Households average 2.28 people. In 2023 there were 390 residents, 3.7% fewer than in 2011, and foreign residents are 8.7%. Declared incomes are slightly above the provincial average.

Most homes here are detached houses and farmhouses with land, some renovated, some needing work. With a country property, check the roof, damp, the septic tank or sewer connection and access from the road, which in the hills may be unsurfaced or steep. The area is in climate zone E, with cold winters.

Earthquake hazard is low. Maretto is in seismic zone 4 on the Civil Protection Department's national scale, along with 112 other municipalities in the province of Asti, and expected ground acceleration in the built-up area is about 0.042 g. In country houses, cracks in the walls and the state of the foundations and rainwater drainage matter more.

The Revenue Agency (Agenzia delle Entrate) cadastral maps cover the municipality and the report finds the land parcel from the address. In the hills, landslide hazard changes from one slope to the next, and the official maps show it for the plot.

Key points

  • Small municipality in the hills around Asti.
  • Estimated average age 46.6, below the provincial 47.9.

Overview

Maretto is a municipality in the province of Asti, in Piemonte. At the end of 2023 it had 390 residents, ranked 86 of 117 municipalities in the province.

Earthquakes

For Italy's Civil Protection Department, Maretto is in seismic zone 4, the lowest-risk zone, where strong earthquakes are very rare. Most municipalities in the province (113 of 117) are in the same zone.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.042 g, a low 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 3.7%. The estimated average age is 47 years, in line with the province. 21% of residents are over 65 (the regional figure is 27%). Foreign residents make up 8.7% of the population. On average, a household has 2.3 members.

Income and climate

In tax year 2024, taxpayers in Maretto declared an average taxable income of 25,381 euros, in line with the province (24,302 euros). The Italian average is 24,895 euros.

Maretto is in climate zone E, with 2,684 heating degree days: heating may be switched on from 15 October to 15 April, for up to 14 hours a day. The same table puts the town hall at 240 metres above sea level.

Public transport

How built-up it is

Radon and contaminated sites

Maretto is not among the radon priority areas designated by the Regione Piemonte in 2023. Radon varies from building to building and can only be known by measuring it, especially on ground floors and in basements.

Official databases list no contaminated sites in Maretto.

Landslide and flood hazard changes from one street to the next even within Maretto: 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

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 10 inhabited census areas in Maretto. Half of the residents live in areas scoring 55 or more.
