These statistics still need to be updated, but at the time of the 2001 Statistics Canada census, Canada's aboriginal population was about 1,066,500, representing 3.4% of Canada's population; however, the population is growing faster than the total population. The highest concentrations will continue to grow, particularly in the prairies and the north. In 2001, Alberta's aboriginal population was approximately 200,000, representing about 5% of Alberta's population. The median age of aboriginal people in Canada and in Alberta was about 12 years younger than the median age of Canadians overall.
I hope that gives some context.
