There is no definitive answer to this question as it depends on how you measure â€œtallest buildings.â€ For example, if you consider only the tallest building in each country, then Saudi Arabia would have half of the tallest buildings. However, if you take into account all tall buildings in each country, then China would have half of the tallest buildings.
To further complicate matters, there is no agreed-upon definition for what constitutes a â€œtall building.â€ The Council on Tall Buildings and Urban Habitat (CTBUH), which maintains a database of tall structures around the world, defines a tall building as any structure that is â€œ taller than 150 meters (492 feet).â€ However, this definition excludes many structures that are commonly considered to be tall buildings, such as TV towers and bridges.
Given these various definitions and measurements, it is difficult to say definitively which country has half of the tallest buildings in the world. However, based on available data and different ways of measuring â€œtallest buildings,â€ it is possible to make some educated guesses about which countries come close to having half of the worldâ€™s tallest structures.
One way to look at this question is by considering the number of skyscrapers (buildings over 150 meters) in each country. According to data from Emporis ,a global database for building information ,as of 2019 China had 4862 skyscrapers ,while United States had 5333 . This means that between these two countries they account for over 50%of all skyscrapers globally . When including other typesof tall structures such as bridges and towers ,China again comes out ahead with 5868 while US has 6234 . So based on this measurement ,we can say that China probably has close to or slightly more than half of all tallest structures globally .
