The only definitions of race that I have been able to locate are in the Equal Employment Opportunity Commission rules. I'm sorry that I don't have the legal cite - my HR dept. copied a page from their book for me over 6 yrs. ago and I've kept it in my HMDA training folder ever since.
WHITE (not of Hispanic origin) -- All persons having origins in any of the original peoples of Europe, North Africa, or the Middle East. (I give Egypt as an example of northern Africa and Iran & Iraq as examples of Middle East, when I do my HMDA training.)
BLACK (not of Hispanic origin) -- All persons having origins in any of the Black racial groups of Africa.
HISPANIC -- All persons of Mexican, Puerto Rican, Cuban, Central or South American, or other Spanish culture or origin, regardless of race.
ASIAN or PACIFIC ISLANDER -- All persons having origins in any of the original peoples of the Far East, Southeast Asia, the Indian subcontinent, or the Pacific Islands. This area includes, for example, China, India, Japan, Korea, the Philippine Islands, and Samoa.
AMERICAN INDIAN or ALASKIAN NATIVE -- All persons having origins in any of the original peoples of North America, AND who maintain cultural identification through tribal affiliation or community recognition.
Any opinion stated above is mine alone and not my employer's.
