Population density (in agriculture: standing stock or plant density) is a measurement of population per unit land area. It is mostly applied to humans, but sometimes to other living organisms too. It is a key geographical term. [1]
Population density (in agriculture: standing stock or plant density) is a measurement of population per unit land area. It is mostly applied to humans, but sometimes to other living organisms too. It is a key geographical term. [1]
Population density is population divided by total land area, sometimes including seas and oceans, as appropriate. [1]
Low densities may cause an extinction vortex and further reduce fertility. This is called the Allee effect after the scientist who identified it. Examples of the causes of reduced fertility in low population densities are: [2]
Population density is the number of people per unit of area, usually transcribed as "per square kilometer" or square mile, and which may include or exclude, for example, areas of water or glaciers. Commonly this is calculated for a county, city, country, another territory or the entire world.
The world's population is around 8,000,000,000 [3] and the Earth's total area (including land and water) is 510,000,000 km2 (200,000,000 sq mi). [4] Therefore, the worldwide human population density is approximately 8,000,000,000 ÷ 510,000,000 = 16/km2 (41/sq mi). However, 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 is 53/km2 (140/sq mi). This includes all continental and island land area, including Antarctica. However, if Antarctica is excluded, then population density rises to over 58 per square kilometre (150/sq mi). [1]
The European Commission's Joint Research Centre (JRC) has developed a suite of (open and free) data and tools named the Global Human Settlement Layer (GHSL) to improve the science for policy support to the European Commission Directorate Generals and Services and as support to the United Nations system.

Several of the most densely populated territories in the world are city-states, microstates and urban dependencies. [6] [lower-alpha 1] In fact, 95% of the world's population is concentrated on just 10% of the world's land. [7] 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.
Deserts have very limited potential for growing crops as there is not enough rain to support them. Thus, their population density is generally low. However, some cities in the Middle East, such as Dubai, have been increasing in population and infrastructure growth at a fast pace. [8]
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. [10] Very densely populated cities are mostly in Asia (particularly Southeast Asia); Africa's Lagos, Kinshasa, and Cairo; South America's Bogotá, Lima, and São Paulo; and Mexico City and Saint Petersburg also fall into this category. [11]
City population and especially area are, however, heavily dependent on the definition of "urban area" used: densities are almost invariably higher for the center only than when suburban settlements and intervening rural areas are included, as in the agglomeration or metropolitan area (the latter sometimes including neighboring cities).
In comparison, based on a world population of 7.8 billion, the world's inhabitants, if conceptualized as a loose crowd occupying just under 1 m2 (10 sq ft) per person (cf. Jacobs Method), would occupy a space a little larger than Delaware's land area.[ citation needed ]

Although the arithmetic density is the most common way of measuring population density, several other methods have been developed to provide alternative measures of population density over a specific area.
Denmark is a Nordic country located in Northern Europe. It consists of the Jutland Peninsula and several islands in the Baltic Sea, referred to as the Danish Archipelago. Denmark is located southwest of Sweden and due south of Norway and is bordered by the German state Schleswig-Holstein to the south, on Denmark's only land border, 68 kilometres long.

In geography, statistics and archaeology, a settlement, locality or populated place is a community of people living in a particular place. The complexity of a settlement can range from a minuscule number of dwellings grouped together to the largest of cities with surrounding urbanized areas. Settlements may include hamlets, villages, towns and cities. A settlement may have known historical properties such as the date or era in which it was first settled, or first settled by particular people. The process of settlement involves human migration.

The Global Human Settlement Layer (GHSL) is a project from the European Commission that creates global geographical data about the evolution of human habitation on Earth. This in the form of population density maps, built-up maps, and settlement maps. This information is produced using new geographic data mining tools and knowledge and analytics based on empirical data.
