I got inspired by our debate and did a little research, doesn't talk about the US in particular, but these statistics are a real eye-opener:
_Only 4% of women around the world consider themselves beautiful (up from 2% in 2004)
•Only 11% of girls globally are comfortable using the word beautiful to describe themselves
• 72% of girls feel tremendous pressure to be beautiful
• 80% of women agree that every woman has something about her that is beautiful but do not see their own beauty
• More than half (54%) of women globally agree that when it comes to how they look, they are their own worst beauty critic
