hmm you're right. I'll remove the first decile and add another one at the end. I'd say the closer you get to the average the more equally the distribution should be, because there's nothing to distribute anymore. But then again, what happens when all the dead ones get taken out? It could end up as extremely depressing^^

edit

ok, here is the one with the 11th decile instead of the 1st and it does look much more friendly (Gini coefficient is 45.1):

That's about the area of the United States, Russia, Nigeria and Argentina.
