Collobiano, a village on the Vercelli plain

Flat, irrigated farmland criss-crossed by canals and ditches surrounds Collobiano, a lowland village in the province of Vercelli not far from the provincial capital. The town hall is at around a hundred and forty metres, and large cultivated fields surround the village, along with the courtyard farmhouses (cascine) typical of this part of Piedmont.

The village has lost many residents in recent years. Istat, the national statistics office, counted 74 in 2023 against 105 in 2011, a fall of 29.5%. With numbers this small, a few families moving away is enough to shift the percentage sharply. The estimated average age is 53.2, above 48.4 for the province, and over-65s make up 32.4%. Declared incomes are in line with the provincial average, slightly above in fact.

House hunters here mostly find detached houses and farmhouses, often large and sometimes in need of renovation. Vercelli is close for work, secondary schools, the hospital and shopping, and a car is essential. The plain is in climate zone E: cold, damp winters with fog, and hot, muggy summers.

Earthquake hazard is low. Collobiano is in seismic zone 4, the lowest, like 80 other municipalities in the province, with expected ground acceleration of about 0.037 g. In an old farmhouse, rising damp, roofs and services matter more.

The Revenue Agency (Agenzia delle Entrate) publishes cadastral maps, and the report finds the land parcel from the address. On a heavily irrigated plain, flood hazard depends on where a house sits in relation to canals and watercourses, and it is read on the official maps for the individual property.

Overview

Collobiano is a municipality in the province of Vercelli, in Piemonte. At the end of 2023 it had 74 residents, among the smallest in the province (80 of 82).

Earthquakes

For Italy's Civil Protection Department, Collobiano is in seismic zone 4, the lowest-risk zone, where strong earthquakes are very rare. Most municipalities in the province (81 of 82) are in the same zone.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.037 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 29.5%. The estimated average age is 53 years, higher than the province average (48). 32% of residents are over 65 (the regional figure is 27%). Foreign residents make up 2.7% of the population. On average, a household has 2.0 members.

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 5 inhabited census areas in Collobiano. Half of the residents live in areas scoring 54 or more.
