In CA, Hispanics and Latinos fall under the category of White or Caucasian.
(Hispanic references those of Spanish lineage, while Latino refers to those from the Latin Church) The black or “negras” in Central America and Mexico, tend to either be Latino, or from Carribean or African ancestry, many generations removed from the present.
Sort of like Kamala Harris whose lineage traces back to black Jamaican slave owners.
