Are all Latinos and Latinas Hispanic?

I am writing a research paper about the depictions of Latinas in the media and have sources where the terms are used interchangeably and others where they are not. What do you think? And what about Chicanas and Chicanos?

As a side note, I don’t like to label people; I just like to think we are all humans, but it I need to do this for my paper. :/
