People - photo wallpapers; Galawallpapers.com : A people is a group of individuals who belong to and function within a particular society. In common usage, the term people may be synonymous with human, or otherwise may carry an exclusive meaning. In general, the word people is a collective noun used to define a specific group of humans. However, when used to refer to a group of humans possessing a common ethnic, cultural or national unitary characteristic or identity, people is a singular noun, and as such takes an s in the plural; (examples: the English-speaking peoples of the world, indigenous peoples). The concept of personhood (who is a person within a society) is the fundamental component of any selective concept of people. A distinction is maintained in philosophy and law between the notions human being, or man, and person. The former refers to the species, while the latter refers to a rational agent (see, for example, John Lockes Essay concerning Human Understanding II 27 and Immanuel Kants Introduction to the Metaphysic of Morals). Central issues of interest to people are the understanding of the human condition and the meaning of life, and survival. Religion, philosophy, and science represent modes and aspects of inquiry which attempt to investigate and understand the nature, behaviour, and purpose of people. Sociology, economics, and politics represent modes by which people investigate how to maximize a collective survival strategy. Population : In sociology and biology, a population is the collection of people, or organisms of a particular species, living in a given geographic area, or space, usually measured by a census. In biology, plant and animal populations are studied, in particular, in a branch of ecology known as population biology, and in population genetics. In population dynamics, size, age and sex structure, mortality, reproductive behaviour, and growth of a population are studied. In biology, an isolated 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. Metapopulation is a group of sub-populations in a given area, where the individuals of the various sub-populations are able to cross uninhabitable areas of the region. Biological dispersal is one of the key elements affecting in such populations. Demography is the study of human populations. Various aspects of human behavior in populations are studied in sociology, economics, and geography. Study of populations is almost always governed by the laws of probability, and the conclusions of the studies may thus not always be applicable to some individuals. This odd factor may be reduced by statistical means, but such a generalization may be too vague to imply anything. Demography is used extensively in marketing, which relates to economic units, such as retailers, to potential customers. For example, a coffee shop that wants to sell to a younger audience, looks at the demographics of an area to be able to appeal to this younger audience. galawallpapers.com - wallpapers 640 x 480 - wallpapers 800 x 600 - wallpapers 1024 x 768 - wallpapers 1280 x 960 - wallpapers 1600 x 1200 - wallpapers 1920 x 1440
