Oleggio, between Novara, Lake Maggiore and the Ticino valley
On the map, Oleggio sits in the north of the province of Novara, between Novara and Lake Maggiore, with land that slopes down to the Ticino valley on its eastern side. The river marks the border with Lombardy, and along its banks the land belongs to the Piedmont regional park of the Ticino valley, with woods, fields and heath. Malpensa airport lies on the opposite bank.
Services are good for a town this size: in Overture Maps data, supermarkets (11) and healthcare facilities (11) are both above the provincial average per resident. The old centre has courtyard houses and low buildings, surrounded by detached homes and blocks of flats. People who work at Malpensa or around Novara have both within driving range, but it is worth checking how much air traffic passes over the property, which varies a great deal from spot to spot.
In 2023 Istat, the national statistics office, counted 14,210 residents, up 4.1% since 2011, making Oleggio number 5 by size among the 87 municipalities in the province of Novara. The estimated average age is 46.0 against 46.7 for the province; over-65s are 23.9% and foreign residents 6.0%. Declared incomes are in line with the provincial average.
All 87 municipalities in the province of Novara are in seismic zone 4, the lowest on the scale kept by the Civil Protection Department, and expected acceleration here is about 0.037 g. In an older house, the roof, damp and the heating and wiring matter more, given the cold winters.
What really makes a difference is where the home stands in relation to the river. On the higher ground, flood hazard is not the same as in the low land near the Ticino, and along the banks that separate the two levels slope stability counts; the report checks both on the official maps for the address. The Revenue Agency publishes its cadastral maps.

Overview
Oleggio is a municipality in the province of Novara, in Piemonte. At the end of 2023 it had 14,210 residents, among the most populous in the province (5 of 87).
Earthquakes
For Italy's Civil Protection Department, Oleggio is in seismic zone 4, the lowest-risk zone, where strong earthquakes are very rare. All 87 municipalities in the province are in the same zone.
In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.037 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 grown by 4.1%. The estimated average age is 46 years, in line with the province. 24% of residents are over 65 (the regional figure is 27%). Foreign residents make up 6.0% of the population. On average, a household has 2.3 members.
Income and climate
In tax year 2024, taxpayers in Oleggio declared an average taxable income of 27,081 euros, in line with the province (26,949 euros). The Italian average is 24,895 euros.
Oleggio is in climate zone E, with 2,606 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 232 metres above sea level.

How built-up it is
Buildings, roads, car parks and other sealed surfaces cover 14.4% of the land in Oleggio, compared with 11.2% in the province and 6.7% in the region. In 2024 built-up land stayed almost the same.
Radon and contaminated sites
Oleggio is not among the radon priority areas designated by the Regione Piemonte in 2023. According to the ISPRA map, the estimated radon emission in the municipality is very high. Radon varies from building to building and can only be known by measuring it, especially on ground floors and in basements.
Official databases list one contaminated site, or site still under investigation, in Oleggio, and 6 more have been cleaned up or closed. The report tells you whether one is close to the address.
Landslides and flooding
Landslide and flood hazard changes from one street to the next even within Oleggio: 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.

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 62 inhabited census areas in Oleggio. Half of the residents live in areas scoring 56 or more.
