The number of 'minorities' in the southis more to do with black people, as that is where they worked as slaves in the last century on the cotton plantations etc. they haven't totally dispersed throughout america yet. The Hispanics are generally a more recent phenomenon, and are more widespread, but principally in California, where demand for cheap labour is high, and Mexicans illegaly enter the country to work there.
