The analysis
Statistical rankings on key metrics
Fractality against betweenness for every census tract in Catalunya, the pair behind Urban Design. A municipal figure is an average of this spread, and the spread is where the decision lives.
Housing & Standard of Living
Key statistics, per parcel.
Area and land qualification come per parcel. Rent, price and score come from the section around it, and only the other 5,141 sections say whether those numbers are any good.
