I'm worried about posts like this making it on the front page: so much information spread so thinly. There isn't any analysis that could explain why or how implicit trends are important or even real.
I sort of think you miss the point. This gives a sense of place and location, which is why I posted it. Some of the data, unfortunately, looks a bit wrong.
What I did find interesting is that it awakened in me a little more curiosity about the lands and countries around me, and the people who inhabit them. That's really not a bad thing!
