A major study by the Medical Journal entitled "The Lancet" shows that indigenous communities in every world country have poor health in comparison with 'non-indigenous' populations. Evidence of this is found in disproportionately high infant mortality rates, loss of land and population, poverty, unemployment, drug and alcohal abuse, and homicide. The study underlines that the concept of indigenous communities can be complicated, in particular in Africa and India. As causes for the poor health of indigenous communities, the study points to caste distinctions, colonialism, and the administration of Aid funding from the UN. More information is available online through a BBC news story.
