Liveability index
A number from 0 to 100 summing up what it is like to live in the area of a property. Here is what it is made of, how much each part weighs and what it does not measure.
The index is our own measure, not official data. We calculate it for every report from the data in the other topics, always with the same method, and put it at the top: at a glance it tells you whether the area is convenient, green and quiet, and where the weak points are.
What it is made of
Seven parts, each with its own score from 0 to 100. The index is the weighted average.
| Part | Weight | How it is measured |
|---|---|---|
| Services on foot | 25% | Schools, clinics, pharmacies and supermarkets: 100 points if there is one within 500 metres, 60 within a kilometre, 0 beyond. Then the average. |
| Transport | 20% | Stops within 500 metres from the transport operators' official timetables: 100 with metro, train or tram, 85 with at least 4 bus routes, 65 with fewer. Where there are no timetables, the distance from the railway station counts and the report marks it as an estimate. |
| Green space | 15% | Two measures combined. First: how much of the surrounding kilometre is woodland, countryside or a large park, from the European CORINE map, which only records areas of 25 hectares and over (40% already scores 100). Second: the best public park or garden within a kilometre, with its real size from OpenStreetMap: 25 points for a garden under a hectare, 50 for a park of 1 to 25 hectares, 75 for a large park over 25; the value is full up to 300 metres and falls to half at a kilometre. Every other park of a hectare or more within 600 metres adds 5 points, up to 10. The two measures add up without going over 100: a house in the woods reaches 100, a city flat next to a large park stays a little below. |
| Natural hazard safety | 15% | Landslides, floods and earthquakes, from the result of the same topics in the report: 100 if favourable, 55 if to consider, 15 if critical. |
| Distance from stations and airports | 10% | Within the statutory 100 or 250 metre bands of a station, or near an airport, the score goes down. |
| Local buildings | 10% | State of repair (60%) and share of buildings built after 1970 (40%), from the 2011 Istat census, the latest one that describes them. |
| Internet connection | 5% | Expected fixed network speed declared by operators to AGCOM: 100 with fibre to the home. |
If data is missing for a part, it is left out and its weight is shared among the others: the report says which are missing. With fewer than four parts out of seven the index is not calculated.
A serious risk cannot be offset
If landslides, floods or earthquakes have a critical result, the index cannot go above 60, even with excellent services and plenty of green space. A home in an area that floods often cannot come out as "excellent".
The bands
- 80-100: excellent liveability
- 65-79: good
- 50-64: fair
- 35-49: modest
- 0-34: poor
What it does not measure
- People. No income, age or origin of residents: the index describes the place, not the people who live there.
- Road traffic. Roads and motorways are not yet in the open data we use: the noise part only looks at trains and aircraft.
- Crime. There is no open data by neighbourhood.
- The flat itself. Floor, orientation and condition of the property are not in the index: they need a visit and a surveyor.
How to read it
Two areas with the same number can be very different: one has everything close by but little green space, the other the opposite. That is why the report always shows the seven parts, with the detail of each and the source of every figure.
Method version 2026-09. If we change weights or thresholds we will say so here, with the date.
