Following the completion of 432 Park Avenue last December 23, there are now officially 100 supertall skyscrapers in the world.

The Council on Tall Buildings and Urban Habitat officially confirmed 432 Park Avenue as the 100th supertall building in the world when the 1,396-foot tall condo tower sold its first unit meeting the council's "partially occupiable" criteria.

432 Park Avenue is considered as the world's tallest all-residential building and is also the 14th tallest building in the world, according to data published by CTBUH. They cited that "advances in lateral resistance technology" prevents the skyscraper from swaying too much as 432 Park Avenue has a slender structure.

CTBUH categorizes buildings as "supertall" when they exceed 300 meters or 984 feet in height. The council noted that the construction of such towers has increased at a rapid rate in recent years. They said that the first 50 supertall skyscrapers in the world took more than 50 years to complete but that number has doubled in a matter of only five years.

While most of the new supertall buildings in the world are located in Asia and the Middle East, CTBUH added that New York "has remained an active center for supertall construction in the Americas."

With seven supertall skyscrapers, New York City has now the second highest number of supertall skyscrapers in the world, next to Dubai which has 18.

Currently, the tallest supertall infrastructure in the world is the Burj Khalifa which is located in downtown Dubai. It was completed in 2010 and stands 2,717 feet with a whopping 163 floors. The building is a joint venture of international companies Skidmore, Owings & Merrill of Chicago and Samsung C&T of South Korea.

The Burj Khalifa is part of the United Arab Emirates' initiative to shift the economy from being oil-based to tourism-based. The large-scale building is a mixed use development that houses 30,000 residences, 9 hotels, 7 acres of parkland, 19 residential towers, a shopping mall and a 30-acre manmade lake.
