Sorry, I think your examples of Skinny are indeed anorexic.  I was a skinny skinny girl, 6',  115 lbs with doctors always giving me shakes and such to put on weight.  I had a healty appetite and ate "vigorously" yet even with their concern and the protein shakes I was never that "skinny".  I was more your "thin" example and if I'd been "skinny" back then I wouldn't have had any modelling contracts - angular bones were not cionsidered attractive back then and they are not a sign of healthy now.

My nieces both suffered eating disorders, Twins - one was bulimic the other anorexic they never got to the point of the bottom images but they certainly got to the "skinny" section and they were  thin to start with. 

Your examples of "skinny" have heads bigger than their bodies - that's anorexic it just hasn't gotten as extreme as it can.  Just because one still has "meat on their bones" doesn't mean they aren't anorexic, it takes a while for the body to eat itself like the bottom pictures.

Yes a woman can be a small  size - Ashley Judd is what a size 6? and looks healthy.  It's all about the angles and the bone protusion.

As for normal - what is that? Your Voluptous examples - and I'm currently built like the brunette -( all those protein shakes LOL) was the ideal 50- 60 years ago and I think it's pretty norm now. 

As for Anna Nicole she goes back and forth between voluptous and full figured. 

Musclebound is freaky - you lose all your breast tissue when you get that big, I'd personally rather keep my curves than have fake ones added in. heh
