Thus, most Argentines are descendants of these 19th and 20th century immigrants, with about 97% of the population being of European or partial European descent and mestizo. Arab descent is also significant (mostly of Syrian and Lebanese origin) and the Jewish population is the biggest in all Latin America (6th in the world). Mestizo population in Argentina, unlike in other Latin American countries, is very low, as is the Black population after being decimated by diseases and wars in the 19th century, though since the 1990s a new wave of Black immigration has been arriving. Native Argentines on the other hand have significant populations in the country's North-West (Quechua, Diaguita, Kolla, Aymara); in the North-East (Guaraní, Mocoví, Toba, Wichí); and in the Patagonia or South (Mapuche, Tehuelche). Asian peoples have increasing minorities in some Buenos Aires neighborhoods and are expanding to other large Argentine cities. Through the centuries people from neighboring countries like Bolivia, Paraguay and Peru have also immigrated to Argentina and established important communities.
