The ones they did collect data from had some confirming examples. South America also had a huge slave trade, so I think the larger number of blacks has brought up the average size in those countries, vs here in the US where blacks only make up about 11% of the population. Keep in mind, these are averages, so while you will have an occasional large white, or large Asian dick, you will not have them as often as a large black dick. "Average" in the white man's world is small in the black man's world.
