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 language
Many indigenous languages are disappearing as there are no longer any young people left to speak those languages, so their remaining speakers are dying out.
In North America, since 1600 at least 52 Native American languages have disappeared. Globally, there may be more than 7,000 languages that exist in the world today, though many of them have not been recorded because they belong to tribes in rural areas of the world or are not easily accessible. It is estimated that 6,809 "living" languages exist in the world today, with 90% having fewer than 100,000 speakers. This means that roughly 6,100 languages are facing a risk of eventual extinction. Some languages are very close to disappearing.
