The list includes the tallest 300 (completed and topped out) buildings in the world. As of 2014, eight of the last ten buildings to have held the record as 'tallest building in the world' are still found in the tallest 300, with the twin towers of the World Trade Center (tallest in 1972 and 1973) no longer standing, and the Woolworth Building not being high enough to make the list.
The term "country" as used in this list encompasses the broader definition of the word, and is inclusive of states and special territories (e.g. Hong Kong).
