Mongrando vs Valdilana
Two municipalities in Biella, Italy, side by side on the five things this site grades — climate & hazards, local vitality, services, affordability and property market. Every figure comes from official open data, and the ones that cannot honestly be compared are marked rather than quietly averaged.
Valdilana
A provisional grade had at least one pillar filled with a neutral 50 rather than measured. Where one side is provisional and the other is not, the gap between the two grades may be partly made of that fill — treat the pillar rows below as the evidence, not the letters.
Pillar by pillar
| Pillar | Mongrando | Valdilana |
|---|---|---|
| Climate & hazards | 42/100 | 46/100 ▲ |
| Local vitality | 43/100 | 71/100 ▲ |
| Services & access | 51/100 | 84/100 ▲ |
| Affordability | 92/100 | not measured |
| Property market | 55/100 ▲ | 49/100 |
Pillar scores are percentile ranks within each municipality's own country, so a 70 in Spain and a 70 in Italy each mean "ahead of 70% of this country's towns" — not that the two places are alike.

How to read this
Grades are computed from official open data — statistics offices, hazard catalogues, land registries and OpenStreetMap — never from reviews, listings or opinion. Each indicator is ranked against the other municipalities of the same country, except the natural hazards, which are absolute 30-year probabilities and therefore mean the same thing everywhere.
That is why some rows above carry no comparison. Spain counts registered tourist dwellings where Italy counts every tourist bed place; each statistics office defines a foreign resident differently; the property-price vintages run from 2018 in Italy to 2025 in Portugal. Putting two such numbers side by side and calling the difference a finding would be inventing one, so the row states the reason instead.
