In 1850 how many Indians were left in USA ?

1850 or 1864?

Records of the Bureau of Indian Affairs

Can’t answer your question exactly.
“It is a reasonable guess that in 1840 some 300,000 Indians dwelt in what is now the Western United States, about the same as the number of people who then lived on Manhattan Island.”
-from “The Indians” Time-Life books (The Old West) p. 23

Here is an interesting article, no numbers given but, interesting.

@fredTOG – You bring up an excellent point. We can’t really solve the problem of hard solipsism.

Also, while learning how to play guitar, it may help to use light guage strings. It’s easier on the strings. Are you learning on an electric or acoustic.

Finally, I am thinking that a bagel may in fact have more carbs than the average donut, although it might depend on the type.

From the little bit of research I just did, the yearly census figures are on microfilm, and even then I couldn’t find any references for the overall Native American population.

I am not understanding why two dates are offered in the OP. 1850 and 1864. I am sure there’s a vast difference in the American Indian population between the dates 1850 and 1864, since that period was when Americans were spreading Westward and Indians. Also, Americans were mating with Indians. If someone was part Indian, are they counted as Indian for this question?
