Caboclo

A caboclo () is a person of mixed Indigenous Brazilian and European ancestry, or, less commonly, a culturally assimilated or detribalized person of full Amerindian descent. In Brazil, a "caboclo" generally refers to this specific type of "mestiço". 
The term, also pronounced "caboco", is from Brazilian Portuguese, and perhaps ultimately from the Tupi "kaa'boc". It means a "person having copper-coloured skin" A person of mixed Indigenous Brazilian and sub-Saharan black ancestry is known as a ""cafuzo"."
In the 1872 and 1890 censuses, 3.90% and 9.04% of the population self-identified as caboclos, respectively. Since then, caboclos are counted as pardos, along with mulattoes (mixed Black-White) and cafuzos (mixed Amerindian-Black).
A survey performed in Rio de Janeiro showed that 14% of Whites and 6% of Pardos reported a mixed Amerindian and White ancestry.
According to the Mexican researcher Lizcano, based on a non genetic based estimation, caboclos ("mestizos") would be 12% of Brazilian population.
Etymology.
The term "caboclo" (which in the Amazon Basin and in Candomblé is usually pronounced without the "l", as "caboco") is said to come from the Tupi word "kari'boka", meaning "deriving from the white". Its primary meaning is "mestizo", "a person of part Amerindian and part European descent." But it may also be used to refer to any Indigenous Brazilian who is assimilated. The term Indian should not be confused with people originating from India in South Asia.
The king of Portugal, D. Joseph I, encouraged marriages between European colonists and Indians in the 18th century; this enabled the European men to settle into families, and resulted in the birth of the first "caboclo" children. Similarly, in the 19th century during the time of rubber soldiers, the government recruited young, primarily white and "mestiço" Brazilian men from Northeastern Brazil and transported them into the Amazonian interior to harvest rubber. The men were never granted permission to leave, and married local native women, fathering more generations of mestiços.
The "caboclo" populations in the Amazon region of Brazil are noted as voracious eaters of the "açaí" palm fruit, which is basic to the traditional diet of the natives. In one study, "açaí" palm was described as the most important plant species because the fruit makes up such a major component of diet (up to 42% of the total food intake by weight) and is economically valuable in the region (Murrieta et al., 1999).
The term "caboco" is also used as an alternate term for the "Orishas" of the Candomblé religion. The caboclo is also an Orisha.
