The report looks at the exact point: landslide and flood risk, seismic zone, price per square metre for the area, services and nearby stops.

For example: Via Subiaco 1, Gerano.

Gerano, a hilltop village between Tivoli and Subiaco

Gerano stands on a hill south of the Aniene valley, at around 500 metres, roughly halfway between Tivoli and Subiaco. The old village takes up the top of the hill, with olive groves and fields spread out below.

People here mostly work elsewhere. Tivoli and the eastern side of Rome can be reached by car, and a few kilometres away, down in the Aniene valley, run the motorway to L'Aquila and Pescara and the Rome to Avezzano railway. Buyers will mainly find stone houses in the centre, sometimes split into small flats, and a few newer houses on the edges.

Istat, the national statistics office, recorded 1,143 residents in 2023, 105 fewer than in 2011, or 8.4%. The average age is 48.9, compared with 46.0 in the province, and 28.0% of residents are over 65. Foreign residents make up 5.4%. Declared incomes are below the average for the province of Rome.

For earthquakes, the municipality is in zone 2 on the Civil Protection Department scale, shared with 96 other municipalities in the province, and expected ground acceleration in the village is 0.155 g. For a flat carved out of an old building, ask about work on the shared structure: roof, load-bearing walls and floors.

The Revenue Agency (Agenzia delle Entrate) publishes cadastral maps, so the report traces the plot from the address. Gradient and landslide hazard on the hill are checked on the official maps for the exact spot.

For anyone buying in Gerano, the building matters a great deal: ask for the design year, whether it met the 2008 seismic standards, and whether any seismic retrofit has been carried out.

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 11 inhabited census areas in Gerano. Half of the residents live in areas scoring 62 or more.
