Length: 70.4 km
--- 2021 ------- 2011 ------- 2001 ------- 1991 --------------- Growth --------------- Area --------- Density
1,715,560 --- 1,595,445 --- 1,608,734 --- 1,738,689 --- +7.5% --- -0.8% --- -7.5% --- 250.2 Km² --- 6,857 inh./Km²
5th densest area on the list so far, after Paris, Moscow, São Paulo and Minsk. As Milan sprawl avoids south and expand endless to west, north and east, we have vast rural areas in south inside the ring whereas most of population of the metro area live outside it. Milan has also two inner ring roads built above old city walls.
Rome is the most interesting ring road in Italy, very regular, 68.2 km-long, covering 344.2 Km², but it's impossible to find administrative divisions matching with it perfectly. Probably between 2.0-2.1 million live inside it.
