How was that calculated; populations and areas of cities are often calculated in very different ways. You have to show these things on a map and describe why you choose what area and how the population number was calculated. Just "what is a park" differs between cities, even what is a parking space is different. E.g. cars needs a lot of room around them on motorways, that areas is not always counted as "motorway" but can be counted as "green space" in some papers. I have not seen ANY good examples of comparisions between cities, but I know these problems comes up alot when we discuss cities here on HN.

I know a lot of people are skeptic about this, but I was surprised as well when I discovered how green Rome is. As a Roman, I also thought that Paris or Berlin were greener or bigger, they are not. > You have to show these things on a map Here it is Berlin and Rome, same zoom level on Google maps https://imgur.com/WU3dWEJ https://imgur.com/WU3dWEJ I've highlighted on the left the area that is actually Rome's territory, Google maps only highlights the area inside the "Grande raccordo anulare" [1], but the city of Rome extends much farther than that, also the area on the beach (the one called Ostia) is actually part of the city even though it is disconnected from it. That's Rome, the city, then there's the Metropolitan City of Rome Capital [2], which is much larger and includes many smaller municipalities around it, which is in turn smaller than Rome metropolitan area [3] [1] https://en.wikipedia.org/wiki/Grande_Raccordo_Anulare https://en.wikipedia.org/wiki/Grande_Raccordo_Anulare [2] https://en.wikipedia.org/wiki/Metropolitan_City_of_Rome_Capital https://en.wikipedia.org/wiki/Metropolitan_City_of_Rome_Capi...
