17. China is the country with the most skyscrapers taller than 400 m worldwide (8, which represents 32% of all of them). There is a very strong correlation between the number of skyscrapers in the cities with at least 200 skyscrapers higher than 100 m and the combined heights of the buildings in each of these cities (0.9983). There is presently no skyscraper between 509 m and 828 m tall.
