Population
Population
density (in agriculture: standing stock and standing crop) is a measurement of population per unit area or unit volume; it is a quantity of type number density. It is frequently applied to living organisms, and most of the time to humans. It is a key geographical term.[1]

Biological population densities[edit] Population
Population
density is population divided by total land area or water volume, as appropriate.[1] Low densities may cause an extinction vortex and lead to further reduced fertility. This is called the Allee effect
Allee effect
after the scientist who identified it. Examples of the causes in low population densities include:[2]

Increased problems with locating sexual mates Increased inbreeding

Monaco
Monaco
in Southern Europe, currently holds the record for being the most densely populated nation in the world.

Mongolia

is the least densely populated country in the world.

This population cartogram of the European Union (2007–2012) uses areas and colors to represent population.

Main article: List of countries and territories by population density 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. The world's population is around 7,500,000,000[3] and Earth's total area (including land and water) is 510,000,000 square kilometers (197,000,000 sq. mi.).[4] Therefore, the worldwide human population density is around 7,500,000,000 ÷ 510,000,000 = 14.7 per km2 (38 per sq. mi). If only the Earth's land area of 150,000,000 km2 (58,000,000 sq. mi.) is taken into account, then human population density increases to 50 per km2 (129 per sq. mile). This includes all continental and island land area, including Antarctica. If Antarctica is also excluded, then population density rises to over 55 people per km2 (over 142 per sq. mile).[1] However, over half[citation needed] of the Earth's land mass consists of areas inhospitable to human habitation, such as deserts and high mountains, and population tends to cluster around seaports and fresh-water sources. Thus, this number by itself does not give any helpful measurement of human population density. Several of the most densely populated territories in the world are city-states, microstates and dependencies.[5][6] These territories have a relatively small area and a high urbanization level, with an economically specialized city population drawing also on rural resources outside the area, illustrating the difference between high population density and overpopulation. Cities with high population densities are, by some, considered to be overpopulated, though this will depend on factors like quality of housing and infrastructure and access to resources.[7] Most of the most densely populated cities are in Southeast Asia, though Cairo

also fall into this category.[8] City
City
population and especially area are, however, heavily dependent on the definition of "urban area" used: densities are almost invariably higher for the central city area than when suburban settlements and the intervening rural areas are included, as in the areas of agglomeration or metropolitan area, the latter sometimes including neighboring cities. For instance, Milwaukee
Milwaukee
has a greater population density when just the inner city is measured, and the surrounding suburbs excluded.[9] In comparison, based on a world population of seven billion, the world's inhabitants, as a loose crowd taking up ten square feet (one square metre) per person (Jacobs Method), would occupy a space a little larger than Delaware's land area.[citation needed] By political boundaries[edit]

Other methods of measurement[edit] Although arithmetic density is the most common way of measuring population density, several other methods have been developed to provide a more accurate measure of population density over a specific area.

Arithmetic density: The total number of people / area of land (measured in square miles or square kilometers) Physiological density: The total population / area of arable land Agricultural density: The total rural population / area of arable land Residential density: The number of people living in an urban area / area of residential land Urban density: The number of people inhabiting an urban area / total area of urban land Ecological optimum: The density of population that can be supported by the natural resources
