> Because of social stigmas attached, many people denied having African ancestry, and after African descended Caribbean workers arrived in Honduras, an active campaign to denigrate all people of African descent, made persons of mixed race anxious to deny any African ancestry. Hence official statistics quite uniformly under-represent those people who have ancestry in favor of a "two race" solution.
Contrasting your example, Japan and Iceland are near 100% homogeneous.
In diversity? Or crime rate?
