Final answer:
More than 90 percent of the Canadian population lives within 150 miles of the US border due to various factors including climate, economy, and history.
Step-by-step explanation:
The percentage of the Canadian population that lives within 100 miles of the US border is quite high. Based on information regarding the distribution of population in Canada, despite it being the second largest country in the world in terms of area, the majority of its population is concentrated near the US border. Specifically, more than 90 percent of Canadians live within 150 miles of the border, indicating a preference for proximity to the United States.
This pattern of settlement has historical, economic, and climatic reasons. The southern regions of Canada, being closer to the border, generally have more temperate climates, better access to trade with the United States, and more developed infrastructure, which have all contributed to this demographic phenomenon in Canada.
