The See Jane project "seeks to engage professionals and parents in a call to dramatically increase the percentages of female characters -- and to reduce gender stereotyping -- in media made for children 11 and under."
In February, it released a study from the Annenberg School of Communication documenting the overrepresentation of male characters in G-rated films: "Where the Girls Aren't: Gender Disparity Saturates G-Rated Films." This month, it added a second Research Brief: "G Movies Give Boys a D: Portraying Males as Dominant, Disconnected and Dangerous." Both reports are available here.
See Jane is a project of Dads & Daughters (DAD), which "provides men with tools to be better fathers and advocates for our daughters."
