Sorry, this was an useless post so now it's gone
I don't think this can be answered for the general case, because those peoples are/were very different from one another. The Pacific Northwest Coast tribes were relatively prosperous and well-fed due to their fishing and whaling. Further up north in Canada, tribes in much less desirable hunting grounds had so little that even in the 1940s their kids were considered seriously malnourished.
This thread is for asking any questions that might seem obvious, tangential, silly or what-have-you. Don't be shy, everyone has holes in their knowledge, though the fewer and the smaller we can make them, the better.
Please be respectful of other people's admitting ignorance and don't mock them for it, as they're doing a noble thing.
To any future monthly posters of SQ threads, please remember to add the "stupid_questions" tag.
