A recent study by the Center for the Study of Women in Television and Film into the on-screen representation of women in the top 100 films of 2011 found that females characters only make up 33% of all characters. Of that 33%, 27% of female characters are in their 20s, 28% in their 30s, 25% are 40 or over, and 4% are 60 or over (presumably leaving 16% under 20). However, male characters 40 or over make up 50%, 8% are 60 or over.
“Female characters remain younger than their male counterparts and are more likely than males to have an identifiable marital status. Further, female characters are much less likely than males to be portrayed as leaders of any kind. This can be partially explained by the tendency to feature female characters under the age of 40.”
