A couple of ideas for you, but it might make the project too complicated for your purposes.
1) Pipeline of films even being considered for those awards - it's hard for either gender (any gender?) without a track record to make a film, really, but especially hard for those with less access to diverse forms of capital.
2) Look at the process of film development and production - so, not just best actors & best actresses, but directors, producers, musicians/film scores, special effects, costume. Nominees and winners.
3) Need to break nominated films down by genre.
4) As a comparison, study what is happening with indie films/film festivals at one end of the scale and international films/festivals at the other end.
Here is a list with links to help that along.

I pitched a series of films to Hollywood execs in the late 1990s and crossed paths with Harvey at a few film festivals. Very bad vibes, so I stayed away.
Decided not to become a director or producer and moved on to other things. : )
