When I took a cultural anthropology class many, many years ago I believe "race" was divided into three categories: Caucasoid, Mongoloid and Negroid. As for what to call yourself ethnically, it really just depends on how far back you want to start counting. I'm American and so are my parents and their parents. Our ancestry covers Scottish, Irish, English, French, German and Swedish. If I went farther back in time I'm sure I could find other ethnic groups to include in my list. As for what to call yourself culturally, it depends on which group you feel you best associate with and who you pay your taxes to. ;-)
