This USA TODAY/MediaPlanet supplement takes a look at gender equality around the world, media stereotypes and examines why it is important to invest more in girls and women globally. "We judge our value in society by seeing ourselves reflected in the culture. I see myself, there I am, I must matter," writes Geena Davis in an editorial on page 18. "But what message are both little boys and girls getting about girls if female characters are one dimensional, sidelined or simply not there at all?" writes Davis in her essay. "The message is that women and girls' value in our society is less than that of men and boys' value."
