Final answer:
The total number of Indigenous people cannot be accurately determined globally, but there are approximately 5 million in the U.S. and 1.5 million in Canada, including First Nations, Inuit, and Métis peoples.
Step-by-step explanation:
It is challenging to determine the exact total number of Indigenous people globally, as the population numbers vary by region and the availability of census data.
However, in the context of the information provided, in the United States, there are around 5 million people who identify as Native Americans. In Canada, the population of individuals identifying as Aboriginal is about 1.5 million, which includes the First Nations, Inuit, and Métis peoples, with the Inuit having a population of around 65,000, and over 587,000 people identifying as Métis.
It's essential to recognize that these numbers reflect specific regions and may not represent the total global Indigenous population.
