Population mountains

Visualising cities by population heightfields. Much better to see it than describe it.

What stands out is each city’s form, a unique mountain that might be like the steep peaks of lower Manhattan or the sprawling hills of suburban Atlanta. When I first saw a city in 3D, I had a feel for its population size that I had never experienced before.

That feeling goes a long way to improve my own geographic instincts. In 1993, there were 14 cities with over 10 million people. Today, 20 additional cities qualify (and another 11 will by 2030), with many sprouting from farmland in our lifetimes. Unless you’ve visited one of these new cities of 10 million people or tracked its growth closely, its scale can be hard to envision.
