Ossona, a farming village west of Milan

In the countryside west of Milan, between Magenta and Legnano, Ossona is one of many villages that have kept a compact centre around the church and the old courtyard farmhouses, while detached houses, small blocks of flats and a few workshop areas have grown up around it. The land is flat and cultivated fields reach the last houses.

People who choose Ossona usually work elsewhere, in Milan or the larger towns nearby. The public transport data record no stops within the municipality, so for commuters the distance to the most convenient station and motorway junction matters; the report measures it from the exact location of the home. In the old core there are courtyard houses, often already split into several units, where shared parts and systems need a careful look.

Istat, the national statistics office, counts 4,318 residents in 2023, up 4.5% on 2011. Ossona is one of the smaller municipalities in the Metropolitan City of Milan, ranked 110 of 133 by population. The average age (45.7) and the share of over-65s (23.0%) match the metropolitan average; foreign residents make up 7.6%. Declared incomes are below the Milan area average, which the city itself pulls up.

Earthquakes are a secondary issue here. Ossona is in seismic zone 4, like 73 municipalities in the metropolitan area, with an expected ground acceleration of around 0.039 g. For houses from the 1970s and 1980s, insulation, the boiler and the windows matter more, since they drive energy bills and the energy rating.

Key points

  • Old courtyard centre on the plain west of Milan.
  • 4,318 residents, up 4.5% since 2011.
  • Ranked 110 of 133 in the Milan area by population.

Overview

Ossona is a municipality in the province of Milano, in Lombardia. At the end of 2023 it had 4,318 residents, ranked 110 of 133 municipalities in the province.

Earthquakes

For Italy's Civil Protection Department, Ossona is in seismic zone 4, the lowest-risk zone, where strong earthquakes are very rare. Most municipalities in the province (73 of 133) are in the same zone.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.039 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 4.5%. The estimated average age is 46 years, in line with the province. 23% of residents are over 65 (the regional figure is 24%). Foreign residents make up 7.6% of the population. On average, a household has 2.3 members.

Income and climate

In tax year 2024, taxpayers in Ossona declared an average taxable income of 26,953 euros, below the provincial average (33,635 euros). The Italian average is 24,895 euros.

Ossona is in climate zone E, with 2,656 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 156 metres above sea level.
