Strictly speaking, the Hispanic is not a race and should be an overlay of some of the others.
I believe that before 1965 or thereabouts Hispanics were included as white in demographic statistics and not a separate category. Anyone who can correct this if it’s wrong is welcome to do so. Also, almost by definition Hispanics are mixed race. There are some that have 100% Indian or Spanish blood but most have at least some from both groups.
