The number of tall buildings constructed is increasing ever more
rapidly. Tall buildings have become more common in cities. For
example, statistics compiled by the CTBUH show that the number
of buildings of 200 meters’ height or greater increased by 441%
from 2000 until the end of 2016. That number grew another 26.5%
between 2016 and 2018 (CTBUH 2018).
