Multiracials constitute the second largest group of Brazil, with around 84,7 million people. The term "Pardo" or mixed race Brazilian is a rather complex one. Multiracial Brazilians appear in hundreds of shades, colours and backgrounds. They are typically a mixture of colonial and post-colonial Europeans with descendants of African slaves and the Indigenous peoples of the Americas. Some individuals may also descend from Maghreb people, Jews, Middle Eastern and Egyptian people, or a more recent ancestry from East or South Asia. Skin colours can vary from light to dark. The "caboclo" or "mestiço" population, those who are a miscegenation of Native and European, revolves around 43 million people. Genetic studies conducted by the geneticist Sergio D.J. Pena of the Federal University of Minas Gerais have shown that the Caboclo population is made of individuals whose DNA ranges from 70% to 90% European (mostly Portuguese, Spanish, Dutch, French or Italian 1500s to 1700s male settlers) with the remaining percentage spanning different Indigenous markers. Similar DNA tests showed that people self-classified as "Mulatto" or White and Black mix, span from 62% to 85% European (mostly descendants of Portuguese, Dutch and French settlers during the colonial period in the Northeast). The "Pardo category" in Brazil also includes 800 thousand Gypsies or Roma people, most of them coming from Portugal but also countries in Eastern Europe and the Baltics. Eurasians can also be classified as Pardo. The majority of them consisting of Ainoko or Hafu, individuals who are a miscegenation between Japanese and European.
