That's an interesting idea ivysaur. Looking at your boobs vs butts map, the few US states with the breast preference (I think a sign of K selection preference) seem to be low density states at higher latitudes. I expect they have a higher percentage of white people than the nation as a whole, they look like mostly republican states, with a few left leaning ones like Maine. So I imagine the government welfare isn't much there, although perhaps there is a greater community bond through families and churches. Europe otoh has a strong breast preference over quite a range of cultures and geographic regions, though government provided welfare is probably much higher there than the US.
I wonder how representative of the region as a whole stats from porn sites can be, although considering the widespread use, it's probably more accurate than most social science polls.
