Jewish? Jewish men have big hips. Sadly I suffer a similar hip to shoulder width ratio. 
Thats not 12% btw. 
I had a jewish friend with the same build. .. like a reverse male build, narrow shoulders/shallow ribcage/wide waist/female bf distribution around the stomach. 
Evidently his wife married him because he was rich and had a huge cock. Go figure.
actually the dude was a good dude, it was just funny to me that he was such a walking stereotype
