Each year, the Council on Tall Buildings and Urban Habitat (CTBUH) publishes a study that examines all 200-meter-plus tall buildings that were completed during the preceding year. The 144 buildings completed in 2017 beat every previous year on record, including the previous record high of 127 completions in 2016. This brings the total number of 200-meter-plus buildings in the world to 1,319, increasing 12.3% from 2016, marking a 402% increase from the year 2000, when only 263 existed. A total of 15 supertalls (buildings of 300 meters or higher) were completed in 2017, tying with 2015, the first year to break this record. The total number of supertall buildings worldwide is now 126, up from 111 in 2016. This fact is even more extraordinary considering that much of the activity has been in the past few years. The 2017 figure represents a 66% increase in just four years. In 2013, there were 76 buildings 300 meters or higher.
