Explain how the world population is distributed
World population is not evenly distributed. Some areas are densely populated-lots of people in a given area e.g. Manila Philippines 43,000 people per square kilometre. Or others are sparsely populated-area is one with very few people living there such as rural or remote areas. Greenland has an average of less than one person per kilometre.
Densely populated
Lots of people in a given area
