It is difficult to figure out exactly how many Iroquois there are today. About 45,000 Iroquois lived in Canada in 1995. In the 2000 census, 80,822 people in the United States said they were Iroquois, with 45,217 of them claiming only an Iroquois background. There were about 30,000 tribal registrations among the Six Nations in the United States in 1995.
