Indigenous peoples of Brazil make up 0.4% of Brazil's population, or about 700,000 people, even though millions of Brazilians have some indigenous ancestry. Indigenous peoples are found in the entire territory of Brazil, although the majority of them live in Indian reservations in the North and Center-Western part of the country. On January 18, 2007, FUNAI reported that it had confirmed the presence of 67 different uncontacted tribes in Brazil, up from 40 in 2005. With this addition Brazil has now overtaken the island of New Guinea as the country having the largest number of uncontacted tribes.
