It's best to use more specific terms based on the context:
* Nationality: You can refer to someone by their nationality, such as "American," "Canadian," "French," etc.
* Origin: You can mention their country of origin, like "He's from Brazil" or "She's from India."
* Ethnicity: If relevant, you can mention their ethnicity, such as "She is Hispanic" or "He is African American."
It's always best to be mindful and respectful of people's identities and avoid using terms that might be considered dehumanizing or insensitive.
