Osio Sopra, between Bergamo and Dalmine on a built-up plain
Osio Sopra is one of the municipalities on the plain south-west of Bergamo, next to Dalmine and Osio Sotto, in a belt where warehouses, roads and housing estates follow one another with hardly a break. The share of built-over land is well above average, a sign of an area packed with homes and businesses and with little farmland left.
Its strength is road access. Bergamo is about ten kilometres away and the Dalmine junction of the A4 motorway is a few minutes' drive, so Milan and Brescia are within reach without crossing the city. Housing is mainly low-rise flats, detached and terraced houses built from the 1980s on, with some older buildings in the historic core. Before settling on a street, look at what surrounds it: industrial areas, busy through roads, lorry traffic.
The population is young for the Bergamo area. Istat, the national statistics office, counted 5,180 residents in 2023, up 2.0% on 2011. The average age is 43.4 against 45.2 in the province, and 18.5% are over 65, against 22.5%. Households have 2.36 members on average, and foreign residents make up 7.9%. Average incomes are close to the provincial figure, just below it.
All 243 municipalities in the province of Bergamo are in seismic zone 3 on the Civil Protection scale, and in Osio Sopra the expected ground acceleration is about 0.102 g. For a house built before current seismic rules, ask to see the structural sign-off; in a block of flats, look at the facades and balconies too.
On the plain the report checks the flood maps for irrigation ditches and canals, which can change from one block to the next. The Revenue Agency (Agenzia delle Entrate) publishes the cadastral maps, so the report can trace the plot from the address.
