14-472: The municipality has a population of 19,669 (31 October 2024) and covers an area of 524.48 square kilometres (202.50 sq mi) of which 138.45 km (53.46 sq mi) is water. The population density is 51.01 inhabitants per square kilometre (132.1/sq mi). The municipality is unilingually Finnish . In old Finnish 'Varkaus' meant strait, and this city is located in the lake district on straits between two parts of Lake Saimaa . An extension of

28-416: A little less than the land area of Puerto Rico , 8,868 square kilometres (3,424 sq mi). 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. Global Human Settlement Layer The Global Human Settlement Layer ( GHSL ) is a project from

42-511: Is 53/km (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). 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

56-454: 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. Population density is population divided by total land area , sometimes including seas and oceans, as appropriate. Low densities may cause an extinction vortex and further reduce fertility. This is called the Allee effect after

70-507: Is around 8,000,000,000 and the Earth 's total area (including land and water) is 510,000,000 km (200,000,000 sq mi). Therefore, the worldwide human population density is approximately 8,000,000,000 ÷ 510,000,000 = 16/km (41/sq mi). However, if only the Earth's land area of 150,000,000 km (58,000,000 sq mi) is taken into account, then human population density

84-581: Is processed automatically to produce analytics and knowledge that methodically and objectively describe the existence of people and developed infrastructure. The GHSL maps human presence on Earth, sourcing information from 1975 and up to 2030. In 2010–2011, the JRC Directorate E "Space, Security & Migration" developed the initial version of the GHSL concept, which was used to create the Atlases of

98-654: 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 . In fact, 95% of the world's population is concentrated on just 10% of the world's land. These territories have a relatively small area and a high urbanization level, with an economically specialized city population drawing also on rural resources outside

112-585: 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. The GHSL processing framework uses a range of data, including census data , archives of fine-scale global satellite imagery , and voluntarily provided geographic information . Data

126-576: The Saimaa Canal passes through the town. Varkaus was born in the late 19th century as an industrial community of the A. Ahlström paper mills. It was a part of the municipalities of Leppävirta and Joroinen until 1929 when Varkaus became a market town . During the Finnish Civil War in 1918 the town was taken over by the Reds , but because of its isolated location in rural Finland, it

140-998: 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. 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. 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. City population and especially area are, however, heavily dependent on

154-547: 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 8 billion, the world's inhabitants, if conceptualized as a loose crowd occupying just under 1 m (10 sq ft) per person (cf. Jacobs Method ), would occupy an area of 8,000 square kilometres (3,100 sq mi)

168-702: The northern outskirts of the town off the Tykkitie road, adjacent to the motorcycle racing and karting facilities. The Speedway circuit is one of the oldest in Finland and held the final of the Finnish Individual Speedway Championship three times. Varkaus is twinned with: This Eastern Finland location article is a stub . You can help Misplaced Pages by expanding it . Population density Population density (in agriculture : standing stock or plant density )

182-443: The scientist who identified it. Examples of the causes of reduced fertility in low population densities are: 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

196-518: Was soon taken by the Whites on the Battle of Varkaus 19–21 February. The whites proceeded to execute every tenth Red soldier. The municipality of Kangaslampi was consolidated to Varkaus on 1 January 2005. The bandy team Warkauden Pallo-35 , or just WP-35, plays in the highest division, Bandyliiga , and has become Finnish champions 16 times. Varkaus Speedway Stadion is a motorcycle speedway on
