Final answer:
Canada and Brazil have similar population distributions with concentrated populations near their respective borders.
Step-by-step explanation:
Canada and Brazil have similar population distributions in that a significant portion of their populations are clustered near their respective borders. In Canada, more than 90 percent of Canadians live within 150 miles of the US border. Similarly, Brazil's most populous cities, such as São Paulo, Rio de Janeiro, and Brasilia, are located in the southern region of the country. These urban areas experience high rates of internal migration and are growing rapidly, resulting in the expansion of self-help housing and the development of slums.
