The brown population (officially called ''pardo'' in Portuguese, also colloquially ''moreno'') is a broad category that includes ''caboclos'' (assimilated Amerindians in general, and descendants of Whites and Natives), ''mulatos'' (descendants of primarily Whites and Afro-Brazilians) and ''cafuzos'' (descendants of Afro-Brazilians and Natives). People of considerable Amerindian ancestry form the majority of the population in the Northern, Northeastern and Center-Western regions.
