Territorial Statistics

An overview


The average size of Italian Nuts2 units, in terms of surface area, is of just over 14,000 km2; in 2017, each unit had an average population of nearly 2.9 million.

In 2017, population density, which is a useful indicator of the impact of human activity on the environment, confirmed at just over 200 inhabitants per km2, with an increase of nearly 7 inhabitants  per km2 over the last 10 years.

In 2017, terrestrial protected areas included in the "Natura 2000" network covered 19.3% of the national territory (a considerable share of protected natural areas) corresponding to an area of over  58,000 km2; protected sea areas included nearly 6,000 km2 of waters area. While the total number of Spa was almost unchanged over 2016, Sci and Sca showed a slight increase to a total of 2,335 sites; almost 74% of them have completed the procedure provided for by the Eu to be designated as Spa (from the previous designation of Sci).


Data on the number of building permits, new dwellings and useful floor area are useful leading indicators of construction activities. After the significant decline between 2006 and 2015, there was a slight recovery in 2017, with a growth in both indicators, new housings and usable floor space.
