Quadroon in the context of "Casta"

The term multiracial people refers to people who are mixed with two or more races and the term multi-ethnic people refers to people who are of more than one ethnicity. A variety of terms have been used both historically and presently for multiracial people in a variety of contexts, including multiethnic, polyethnic, occasionally bi-ethnic, biracial, mixed-race, Métis, Muwallad, Melezi, Coloured, Dougla, half-caste, ʻafakasi, mulatto, mestizo, mutt, Melungeon, quadroon, octoroon, griffe, sacatra, sambo/zambo, Eurasian, hapa, hāfu, Garifuna, pardo, and Gurans. A number of these once-acceptable terms are now considered offensive, in addition to those that were initially coined for pejorative use.

Individuals of multiracial backgrounds make up a significant portion of the population in many parts of the world. In North America, studies have found that the multiracial population is continuing to grow. In many countries of Central and South America, mestizos make up the majority of the population (Panama, Bolivia, Peru, Colombia...) and in some others also mulattoes. In the Caribbean, multiracial people officially make up the majority of the population in the Dominican Republic (73%) and Aruba (68%).

In the British colonies in North America and in the United States before the abolition of slavery in 1865, free Negro or free Black described the legal status of African Americans who were not enslaved. The term was applied both to formerly enslaved people (freedmen) and to those who had been born free (free people of color), whether of African or mixed descent.

Sacatra was a term used in the French Colony of Saint-Domingue to describe the descendant of one black and one griffe parent, a person whose ancestry is 7⁄8 black and 1⁄8 white. It was one of the many terms used in the colony's racial caste system to measure one's black blood.

The etymology of sacatra is uncertain; Félix Rodríguez González linked it to Spanish sacar 'take out' and atrás 'behind'; thus, a sacatra is a slave who is not kept in the house or at the front as a lighter-skinned servant might be.
