This is an interesting response that points out ambiguity in it all. Depending on what you're reading / what statistic is being derived, often times you see Hispanic / Latino included as white and not brown.
"A 2014 Pew Research Center survey found that one-third of US Latinos identify as "mestizo", "mulatto", or another multiracial identity.[21] Such identities often conflict with standard racial classifications in the United States: among Latino American adults surveyed by Pew Research who identified as multiracial, about 40% reported their race as "white" on standard race question as used on the US Census; 13% reported belonging to more than one race or "mixed race"; while about 20% chose "Latino" as their race." - Wikipedia
