Boring question #53: Are there more nationalities represented in anime or not?

If one takes a look at anime or manga one might notice straight off is half the males look Asian and the other half Western or Caucasian. The gals on the other end mostly look Western or Caucasian, and a few look Asian. The ones that look Asian to me do not look like the Asians you would see in the Philippines, Laos, or Vietnam, with darker skin. Most noticeable is you do not see any Hispanic or African looking males nowhere in sight. Why do you suppose that? I have my theories but no one cares to hear them so why waste the time, you might be more familiar with the art form and have a factual reason as to why this is. Maybe you know some non-traditional anime out there you know about that is more nationality represented? If you have seen such, do you have a link?
