Title: Demographics of the world
Content:   The world's population is 7 billion and Earth's total surface area (including land and water) is 510 e6km2. Therefore, the worldwide human population density is 7 billion ÷ 510 e6km2 = 13.7 /km2. If only the Earth's land area of 150 e6km2 is taken into account, then human population density increases to 46.7 /km2. This calculation includes all continental and island land area, including Antarctica. If Antarctica is also excluded, then population density rises to 50 /km2. Considering that over half of the Earth's land mass consists of areas inhospitable to human inhabitation, such as deserts and high mountains, and that population tends to cluster around seaports and fresh water sources, this number by itself does not give any meaningful measurement of human population density. Several of the most densely populated territories in the world are city-states, microstates or dependencies. These territories share 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.
Title: Population density
Content:  Population density is the number of people per unit of area, usually quoted per square kilometre or square mile, and 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 7,800,000,000 and Earth's total area (including land and water) is 510,000,000 km2 (197,000,000 sq. mi.). Therefore, from this very crude type of calculation, the worldwide human population density is approximately 7,800,000,000 ÷ 510,000,000 = 15.3 per km2 (40 per 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 
Title: Metro (city)
Content:  Metro is spread over an area of 68.74 km2, with the built up area consisting of 24.57% of the city, or 16.88 km2. As of 2010, it had a population of 145,346, with a density of 2,116.2 people per km2 (5,480.9/sq mi); the 2020 Census resulted in a population of 168,676, giving a density of 2,453.8 people per km2 (6,355.5/sq mi). The city is built around the Dutch land use planning system. Its economic and political hub is in the center, in the area around the city park. All five provincial and national roads that transect Metro meet in this area. Northern Metro is a 
Title: List of cities proper by population density
Content:  This is a list of cities worldwide by population density. The population, population density and land area for the cities listed are based on the entire city proper, the defined boundary or border of a city or the city limits of the city. The population density of the cities listed is based on the average number of people living per square kilometer or per square mile. This list does not refer to the population, population density or land area of the greater metropolitan area or urban area, nor particular districts in any of the cities listed.
Title: City proper
Content:   In some countries, city limits that act as the demarcation for the city proper are drawn very wide, or very narrow. This can be a recurring cause for controversy. "List of cities by surface area" lists little known cities that are larger than many countries. By area, the city of Altamira, Brazil (population 84,000) is bigger than Greece. The City of Kalgoorlie-Boulder (population 32,000) covers more area than Hungary, Portugal, Austria, or Ireland. While these examples cause limited debate, cities in China are a source of continuing contention. The Chinese city of Hulunbuir in Inner Mongolia was recognized as the largest city in the world by area until 2018 (see image caption above). 
Title: Kitakyushu
Content:  , the city had an estimated population of 945,595 and a total area of 491.95 km2. The average population density is 1922 /km2. It is now the country's 15th most populated city. It has a much larger total area than that of Fukuoka which is only 343.39 km2.
Title: List of city districts by population density
Content:  This is a list of the most densely populated city subdivisions (30,000+ inhabitants/km2) in the world with an area of at least 1 km2. Most are districts of large cities and may vary significantly in regional importance. Note this list is not exhaustive as data is hard to come by for many places on earth.
Title: Greater London
Content:  With increasing industrialisation, London's population grew rapidly throughout the 19th and early 20th centuries, and it was the most populated city in the world until overtaken by New York in 1925. Its population peaked at 8,615,245 in 1939. There were an estimated 7,753,600 official residents in mid-2009. London's wider metropolitan area has a population of between 12 and 13 million depending on the definition of that area. According to Eurostat, London has been the most populous city and metropolitan area of the European Union. The region covers an area of 1,579 square kilometres. The population density is 4,761 people per square kilometre, more than ten times that of any other British region. In terms of population, London is the 25th largest city and the 17th largest metropolitan region in the world. It is ranked 4th in the world in the number of US dollar billionaires residing in the city. It ranks as one of the most expensive cities in the world, alongside Tokyo and Moscow.
Title: Brno
Content:  This tool shows only cities with population over 300,000 in radius of 300 km.
Title: Metropolitan City of Cagliari
Content:   As 470 km2 are covered by forests, lagoons, ponds and salt marshes, the really populated area is 777.8 km2. So the real population density rises to 553 inhabitants/km2. In 1861, the municipalities of the current metropolitan city had 67,063 inhabitants, while the city proper had 33,491. Since then the city had a population growth of 461%, while the metropolitan municipalities as an all had an increase of 644%. In that year Cagliari had a population that was the 50% of the metropolitan area, while now it is only the 36%.
