This chart, showing population growth in almost 600 cities worldwide, is basically too complicated to understand with the naked eye. You’ll want to click through to the original, which allows you to highlight cities from Tokyo at the top to Ta’izz (Yemen) at the bottom, and see their population trajectory from 1950 to a projected 2025.
What’s really striking, once you’ve clicked around a bit, is how fast cities in the developing world are gaining, while cities in industrialized nations hold steady or shrink. Once you’re looking at the original chart, go all the way to the right-hand side and click on the fourth line down (it’s a blue one). That’s Dhaka, the capital of Bangladesh, and that line says it all.
