American Indian Wars
The 2010 United States Census found 2,932,248 Americans who identified themselves as being American Indian or Alaskan Native, about 0.9% of the US population. The Canada 2011 Census found 1,836,035 Canadians who identified themselves as being First Nations (or Inuit or Métis), about 4.3% of the Canadian population. No consensus exists on how many people lived in the Americas before the arrival of Europeans, but extensive research continues to be conducted. Contemporary estimates range from 2.1 million to 18 million people living on the North American continent prior to European colonization, but the US Census Bureau stated in 1894 that North America was an almost empty continent in 1492 and that Indian populations "could not have exceeded much over 500,000."
Indigenous peoples of the Americas
Indigenous peoples of Brazil make up 0.4% of Brazil's population, or about 817,000 people, but millions of Brazilians are mestizo or have some indigenous ancestry. Indigenous peoples are found in the entire territory of Brazil, although in the 21st century, the majority of them live in indigenous territories in the North and Center-Western part of the country. On January 18, 2007, Fundação Nacional do Índio (FUNAI) reported that it had confirmed the presence of 67 different uncontacted tribes in Brazil, up from 40 in 2005. Brazil is now the nation that has the largest number of uncontacted tribes, and the island of New Guinea is second.
