In the mid 1700's when Europeans and Spanish arrived there were about 18,000 Haida.
Thank you for showing us your mistake. In case you didn't notice, your 1rst post said :
The Haida have 18,000 years of unbroken history
Having a pop of 18.000 & having 18.000 years of unbroken history is not exactly the same thing.
So, this leads me to conclude that you do not know the difference between history & population, which leads me to this valid question :
"Do the ward nurses know you're out of your locked room?"
