Territorial Statistics

Italy and its regions

The Italian regions and autonomous provinces vary widely in terms of population and surface area.  Lombardia has the largest population, whereas Umbria, Basilicata, the two autonomous provinces of Trento and Bolzano, Molise and Valle d'Aosta, all located in the Alpine or Apennine mountain areas, have populations of less than 1 million.

With regard to population density, the sharpest differences in comparison to the national average of 201.0 inhabitants per km2 were seen in municipalities belonging to the two groups at the extreme ends of the spectrum in terms of territorial area (up to 1,000 hectares or over 25,000 hectares, respectively). Almost all the regions with a large population size (of more than 4 million inhabitants) had a density of over 200 inhabitants per km2.

In 2016, Sicilia and Sardegna showed the highest regional values of terrestrial areas in the Natura 2000 network (over 4,500 per km2 for each region). At the national level, the highest  incidence of protected areas was registered in Abruzzo, the lowest in Emilia-Romagna. 21.5 percent of the territory of the South and Islands was included in the Natura 2000 network, while the Centre presented the lowest incidence. Considering the partitioning of the areas, Lombardia had the largest number of protected areas (243), followed by Sicilia (238) and Lazio (200).

With regard to building permits, the indicators of the number of new dwellings and the useful floor area per 1,000 households continued the decline started in 2005. In the 2004-2014 period, the gap between the Centre and North and the South and Islands reduced to zero. At the regional level, however, the situation was still rather heterogeneous, the lowest values being found in Toscana and Liguria, the highest in the autonomous province of Bolzano.
