    Population density is a measurement of population per unit area or unit volume. It is frequently applied to living organisms, and particularly to humans. It is a key geographic term.Population density is population divided by total land area.For humans, population density is the number of people per unit of area usually per square kilometer or mile (which may include or exclude cultivated or potentially productive area). Commonly this may be calculated for a county, city, country, another territory, or the entire world.

    The world's population is 6.8 billion and Earth's total area (including land and water) is 510 million square kilometers (197 million square miles).Therefore the worldwide human population density is 6.8 billion ÷ 510 million = 13.3 per km² (34.5 per sq. mile).

    To work it out you divide the amount of people living there by the area of the place.
