Strong non-white character

Sulu and Uhura are both strong non-white characters in Star Trek.

A strong non-white character is simply a character in fiction or a person in non-fiction who is not ethnically white and is presented as an individual character with their own goals making them important to the work in a beneficial way. Despite the fact that white people only make up around 58% of the population of the USA, they account for the vast majority of characters or people in published media, and, when people of color do show up, they're usually an ancillary character or villain, not a protagonist, and they're often depicted in a stereotypical manner (or played by a white actor). A similar exclusion of non-white characters exists in most other Western cultures as well. This lack of representation shows an underlying problem with all Western media industries. Because of this, the very fact that a work of media even has a non-white character is worth noting, but having a strong non-white character is rare enough to be striking. In recent years, there has been an increase of strong non-white characters, but they're still represented far less frequently than their population percentage would suggest.

Personal

The bulk of the media I experienced as a child was almost exclusively white. I think the only show I watched in childhood which had a diverse cast was Sesame Street. Looking back at my lists of favorite movies, TV shows, books, video games, etc., the vast majority of them feature only white main characters with the occasional token non-white person. Later in life, when I began learning about the importance of representation in the media, it became more important for me to purposely expose myself to media with strong non-white characters and keep track of which media has them.
