The average population density of the
world is 47 persons per square mile. Continental densities range from no
permanent inhabitants in Antarctica to 211 per square mile in Europe. In the
western hemisphere, population densities range from about 4 per square mile in
Canada to 675 per square mile in Puerto Rico. In Europe the range is from 4 per
square mile in Iceland to 831 per square mile in the Netherlands. Within
countries there are wide variations of population densities. For example, in
Egypt, the average is 55 persons per square mile, but 1,300 persons inhabit each
square mile in settled portions where the land is arable. High
population densities generally occur in regions of developed industrialization,
such as the Netherlands, Belgium, and Great Britain, or where lands are
intensively used for agriculture, as in Puerto Rico and Java.
Low a A. 1,300 persons B. few inhabitants C. pyramids D. many settlements
