Hi Jill!
Thanks for your question.
I'll be writing about this topic very soon! In a nutshell, a Chicano or Chicana is a Mexican-American, usually born in the US.
Since we were raised in the US, we have different experiences than Mexican Nationals, particularly in terms of Spanish language aptitude, discrimination, and poverty.
We are Latinos and/or Hispanics -- depending on how each individual relates to the categories.
Saludos!
