This chart showing the height of the tallest skyscrapers built over time, made by The Economist, can get a little hectic with what seems like axises and data points that go beyond x, y and z and on to some unknown letter but it is deeply interesting. It shows what the tallest building built in which year was, how tall it was, which continent it was built on, highlights iconic buildings and lists what world event was going on during specific years.
I told you there was a lot going on.
It's interesting that for over a century (1885-1990), the tallest building built in any given year was almost always built in North America. But ever since then, China, the Middle East and the rest of Asia have been getting in on the skyscraper race and have been reaching unfathomable heights.
