All of the top 15 cities with buildings over 150 meters (492 feet) are located in Asia except for New York and Chicago. Cities in Asia account for 1,078 buildings of the total 1,611 located in the top 25 cities, which is 67%.
Of all the buildings over 500 meters being proposed or under construction right now, only One World Trade Center in New York City will not be located in Asia. If in 1960, 90% of the tallest buildings in the world were located in North America, in 2010 the percentage has dropped to 30%, with Asia and the Middle East having over 60%.
