In 1960, before contact, the population was 126 people, according to the genealogies which I have reconstructed. The flu epidemic resulting from contact killed 86 people. The census I undertook in 1961, showed a total of 40 people, 14 men, 7 women, and 21 children. In 1961, a smallpox epidemic affected the group, killing 6 more people. The medical assistance provided mainly by Dr. João Paulo Botelho Vieira Filho, of the Escola Paulista de Medicina [of São Paulo], who has visited the group since the beginning of the 60s, has made possible a broad demographic recovery. In 1985, Iara Ferraz recorded a total of 109 pessoas, 52 men and 57 women. In 1997, the population total was 185 people, according to the survey done by the medical doctor João Paulo Botelho Vieira Filho.
