Greggio, among the rice fields north of Vercelli

Greggio is a farming village on the Vercelli plain, north of the provincial capital. Around it there is little but rice paddies, irrigation channels and farmsteads, and the river Sesia runs not far away. Many residents work in Vercelli or nearby towns, and that is also where people go by car for secondary schools, the hospital and bigger shopping trips.

Buyers here mostly find courtyard houses, rural buildings that once belonged to farms and a few newer detached homes. With the paddies flooded for much of the year, water sits close to the surface, so in older houses check for rising damp on the ground floor, the state of any cellar and drainage around the building. For plots near the Sesia and the channels, the report checks the official flood maps at the exact address.

Istat, Italy's national statistics office, counted 324 residents in 2023, against 382 at the 2011 census, a fall of 15.2%. The estimated average age is 49.7, slightly above the provincial 48.4, and people over 65 make up 30.6%. Foreign residents account for 8.6%. Declared incomes are below the average for the province of Vercelli.

Earthquake risk is low. Greggio is in seismic zone 4 on the Civil Protection Department's national scale, like 81 of the 82 municipalities in the province, with expected ground acceleration in the built-up area of about 0.037 g. In a rural building the roof, beams and timber floors matter more, and a surveyor should look at them before you sign.

The Revenue Agency (Agenzia delle Entrate) publishes cadastral maps for Greggio, so the report can go from the address to the plot the building stands on.

Overview

Greggio is a municipality in the province of Vercelli, in Piemonte. At the end of 2023 it had 324 residents, ranked 57 of 82 municipalities in the province.

Earthquakes

For Italy's Civil Protection Department, Greggio 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.

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 Greggio. Half of the residents live in areas scoring 60 or more.
