Nominations for Supporting Actresses Likely To Be More Diverse Than Other Categories

From 2000 to 2022, nominees for Best Supporting Actress are more likely to have diverse backgrounds compared to actors nominated for Best Actress, Best Actor and Best Supporting Actor. 

Actors are classified by ethnicities they self-identified with or are largely classified with. Actors who claim a small percentage of Indigenous heritage with largely European backgrounds are classified as white.

Actors with mixed heritage from two or more non-European countries are classified as actors with "two or more" ethnicities.
