Most of Northeastern Brazil is of a genetically balanced mixed race; Portuguese, various displaced African groups, and native blood have created a new stabilized "ethnicity". Fortunately, these people live agrarian lifestyles or are packed into impoverished urban areas, incapable of living the consumer life. The government uses the epithet brown, or Pardo, to denote the racial identity of these newly formed groups. Curiously, they have a cultural identity of a greater degree than most single raced American's, but it's a good model for how abjection and poverty are a catalyst for interbreeding.
