What we know, and what we don't
The figures above are official ISTAT data. The Need Index here uses decline and median age only.
We have not profiled Castellanza yet. That means no Liveability score and no trades register — we don't know whether it has a school, a doctor or usable broadband, and we would rather say so than guess. It is a gap in our research, not a verdict on the town.
