I was wondering what the world looked like back in the 1400s. Were there major migrations going on? That was on the eve of the migration of Europeans all over the world, and their forcible displacement of Africans via slavery to the Americas. Was there migration as big as the Turks to Anatolia in the 6th through 11th century?
It's incredible to think of Europeans swamping North America and Australia and New Zealand, and making a pretty big dent in South America too. Sad to think about the loss of native American cultures.
So what is the balance in the world now? It was somewhat hard to find. For one thing, racial classification is very much out of favor. However, I did find this:
I liked that the world wasn't divided into white, black, American Indian, and Asian. It makes sense to have more divisions in Asia. Does the entry for South/Central American make sense? Maybe it does. Perhaps there are has been more mixing there of European, American, and African stocks.
I then thought of a Cambodian babysitter my kids had 20 years ago. She had lighter skin and finer features than the Cambodians at the bus stop near me. She explained that she was half Chinese, which was one reason her family fled Cambodia. The Chinese diaspora has been extensive, like the European diaspora. Then I found this graph of the Indian diaspora, which is also fascinating.
Then there was this list of ethnic groups. My group is there, and so is my spouse's. But no Vikings? That's sad.
As a thought experiment, what groups will be on a pie chart in 200 years or 500 years? It almost makes me hope that I'll have an afterlife and can peek in on Earth to watch.
Ssdly, I didn't save a link to a genetic study showing that if there were racial categories, there should be only three of them: pygmies, Bushmen, and everyone else. I have no trouble believing that.
Update 4/5/18. Japanese population has already peaked (in 2008) and is declining. China, even with their one-child policy, still hasn't peaked (source). By the way, I'm in favor of a stabilization and decline in world population.
