Who’s Hispanic? - Pew Hispanic Center
Q. But the Census also asks people about their race and their ancestry. How do these responses come into play when determining if someone is Hispanic?
A. They don't. In the eyes of the Census Bureau, Hispanics can be of any race, any ancestry, any country of origin. The result is that there are varying patterns relating to where people come from and how they choose to identify themselves on the Census. For example, some 99% of all immigrants from Mexico call themselves Hispanic. But just 87% of immigrants from Venezuela adopt this label, as do 86% of immigrants from Argentina, 70% of immigrants from Spain, and only 67% from Panama. As for race, 54% of all Hispanics in the U.S. self-identify as white, 1.5% self-identify as black, 40% do not identify with any race and 3.8% identify as being two or more races.
