Diversity also covers disability, age, gender and people from lower socioeconomic
groups as far as I can see from the BFI leaflet:

Oh, and also an option for 'substantial local employment' for the crew thing if you're outside of greater London.
Sounds good to me.
Though I wonder what they'll do with movies like "All is Lost" which has literally 1 dude (Robert Redford) in it. Whether it would be straight up disqualified or if they'll look at some movies on a case-by-case basis.
