Scientists have even studied how happiness correlates with population density. This list is not inclusive-the way society structures its living spaces affects many other fields of study as well. Infrastructure: how population density drives specific requirements for energy use and the transport of goods.Epidemiology: how densely populated areas differ with respect to incidence, prevalence, and transmission of infectious disease.Ecology: how increasing population density in certain areas impacts biodiversity and use of natural resources.Key areas of study include the following: Census or UN statistics to understand and better predict resource use and health trends. Departments of Energy and Agriculture all use population data from the U.S. Global Change Research Program, and the U.S. Energy Information Administration, the U.S. For example, the World Health Organization, the U.S. Population density data can be important for many related studies, including studies of ecosystems and improvements to human health and infrastructure. These terms do not have globally agreed upon definitions, but they are useful in general discussions about population density and geographic location. Dense population clusters generally coincide with geographical locations often referred to as city, or as an urban or metropolitan area sparsely populated areas are often referred to as rural. Therefore, the most useful data describes smaller, more discrete population centers. However, data on human population density at the country level, and even at regional levels, may not be very informative society tends to form clusters that can be surrounded by sparsely inhabited areas. Globally, statistics related to population density are tracked by the United Nations Statistics Division, and the United States Constitution requires population data to be collected every 10 years, an operation carried out by the U.S. In the case of humans, population density is often discussed in relation to urbanization, immigration, and population demographics. Population density can be used to describe the location, growth, and migration of many organisms. The number of individuals living within that specific location determines the population density, or the number of individuals divided by the size of the area. Minneapolis-St.A population is a subgroup of individuals within the same species that are living and breeding within a geographic area. Miami-Fort Lauderdale-West Palm Beach, FL MSA Philadelphia-Camden-Wilmington, PA-NJ-DE-MD MSA Washington-Arlington-Alexandria, DC-VA-MD-WV MSA New York-Newark-Jersey City, NY-NJ-PA MSA metropolitan statistical areas ranged by population. These areas, placed further away from large centers, have at least one urban core of 10 thousand but less than 50 thousand citizens. Micropolitan Areas are the minor areas marked a lighter shade of green on this map. The largest population areas are sometimes incorporating many U.S. Metropolitan Areas have at least one urban core of at least 50 thousand population. Census Bureau’s gigantic latest map shows 392 metropolitan and 547 micropolitan statistical areas. Census Bureau divides these settlements into metropolitan and micropolitan statistical areas.īelow, the U.S. The United States is the third most populated nation globally, with 331 million people who live in 19,502 incorporated cities and towns of these, 16,410 had a population under 10 thousand while, and only ten cities had one million or more.
