Wow! Immigration patterns and empires explained.*
I notice the most spectacular leap was the Ottoman Empire, then London, then new York.

It also seems to mirror how culture and technology change at a faster and faster rate every year. I mean Istambul took several hundred years to reach its peak, but then London took just one century, and then NY did it in about 50 years.



*And where the fvck is Spain? We were humungous.
