For the use of the word ''population'' in statistics, see statistical population.''In sociology, and biology, a population is the collection of human beingspeople—or organisms of a particular species—living in a given geographygeographic area.Population is studied in a wide variety of ways and disciplines. In population dynamics, size, age and sex structure, mortality, reproductive behaviour, and growth of a population are studied. Demography is the study of human population dynamics. Other aspects are studied in sociology, economics, and geography. Plant and animal populations are studied in biology, in particular in that branch of ecology known as population biology, and in population genetics. In biology, a ''population'' denotes a breeding group whose members breed mostly or solely among themselves, usually as a result of physical isolation, although biologically they could breed with any members of the species.Population density is a measure of the number of people or organisms per unit of area. Variants may express the population per unit of habitable, inhabited, productive (or potentially productive), or cultivated area. A particular area of land is said to have a carrying capacity, representing the maximum population which it can support. Some observers of societyhuman societies believe that the concept of carrying capacity also applies to the human population of the Earth, and that unchecked population growth can result in a "Malthusian catastrophe". Others dispute this view.Populate as a verb means the process of populating a geographygeographic area, as by reproductionprocreation or immigration.
