I love the work that LSE Cities (London School of Economics) is doing with Urban Age. If you haven’t yet checked out their site, you should do that now. If you’re a city geek, it’s the kind of site you can get lost in for hours. Especially if you’re a sucker for great diagrams like I am.
Here’s one I found today that shows where cities are growing in the world:
Each circle represents a city (well, metropolitan area). The dark green dot is the city’s population in 1950. The lighter green dot is the city’s population in 1990. And the yellow dot is the city’s projected population by 2025. Click here for a larger version of the map.
What’s fascinating about this diagram is that you can so clearly see how the most significant population growth has shifted away from the West to the rest of the world and in particular Asia. That is, those dots have more yellow than green.
We, of course, already knew this was happening. And population is just one dimension. But it’s still interesting to see this in diagram form. We are living through the rise of the East. And this diagram is a reminder of that.
