![]() However, some cities in the Middle East, such as Dubai, have been increasing in population and infrastructure growth at a fast pace. Thus, their population density is generally low. 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.ĭeserts have very limited potential for growing crops as there is not enough rain to support them. In fact, 95% of the world's population is concentrated on just 10% of the world's land. Several of the most densely populated territories in the world are city-states, microstates and urban dependencies. 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. ![]() World environments map provided for comparison with maps above However, if Antarctica is excluded, then population density rises to over 55 persons/km 2 (over 142 per sq. This includes all continental and island land area, including Antarctica. mi.) is taken into account, then human population density is 50/km 2 (129 per sq. Therefore, from this very crude type of calculation, the worldwide human population density is approximately 7,800,000,000 ÷ 510,000,000 = 15.3/km 2 (40 per sq. Commonly this is calculated for a county, city, country, another territory or the entire world. 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. Main article: List of countries and dependencies by population density Increased problems with locating sexual mates.Examples of the causes of reduced fertility in low population densities are: This is called the Allee effect after the scientist who identified it. Low densities may cause an extinction vortex and further reduce fertility. Population density is population divided by total land area, sometimes including seas and oceans, as appropriate. In simple terms, population density refers to the number of people living in an area per square kilometre, or other unit of land area. It is mostly applied to humans, but sometimes to other living organisms too. Population density (in agriculture: standing stock or plant density) is a measurement of population per unit land area. In relation to the equator it is seen that the vast majority of human population lives in the Northern Hemisphere, as 67% of Earth's land area is there. ![]() Population density (people per km 2) map of the world in 1994.
