For example: Via Giacomo Bove 1, Maranzana.

Maranzana, birthplace of Giacomo Bove in southern Asti province

Giacomo Bove, the nineteenth-century Piedmontese explorer, was born in Maranzana. The village lies in the south of the province of Asti, close to the border with the province of Alessandria, on hills at around two hundred and seventy metres. Acqui Terme and Nizza Monferrato are the towns people rely on for services, secondary schools and work.

It is a hill village with houses grouped in the centre and farmhouses scattered around. For a buyer, the questions are practical: what the access road is like, how far the pharmacy, schools and supermarket are (the report measures this from the address), and the state of the roof, walls and systems. On sloping plots, have any cracks and retaining walls checked, and read the official landslide hazard maps.

The population has fallen hard: 219 residents in 2023 according to Istat, Italy's national statistics office, against 307 in 2011, a drop of 28.7%. The estimated average age is 54.0, against 47.9 in the province of Asti, and over-65s make up 36.5%. Foreign residents account for 7.8%. Declared incomes are slightly below the provincial average.

On the Civil Protection Department's earthquake scale, the province of Asti is almost entirely in zone 4: only 4 municipalities are in zone 3, and Maranzana is one of them. The figure that matters more, though, is the expected ground acceleration in the built-up area, about 0.056 g, which remains low. The Revenue Agency (Agenzia delle Entrate) publishes the cadastral maps, and the report traces the land parcel from the address.

Even in zone 3, seismic standards apply to new buildings: for an older building, ask about the design year and any structural work.

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 6 inhabited census areas in Maranzana. Half of the residents live in areas scoring 60 or more.
