Answer 1

ANSWER

                                                       For humans, population density is the number of people per unit of area, usually quoted per square kilometer or square mile (which may include or exclude, for example, areas of water or glaciers).

                                  Commonly this may be calculated for a county, city, country, another territory, or the entire world.
